Postoperative infection

Arjun Luthra, commercial director of BioInteractions, shares how Surface Active Therapeutics represent a leap in safeguarding medical devices. In the ever-evolving landscape of healthcare, the need for advanced protective measures for medical devices has never been more critical. Surface Active Therapeutics represent a groundbreaking leap in safeguarding these devices, ensuring they remain free from infections and complications throughout their lifespan. As healthcare-associated infections (HCAIs) continue to pose significant challenges, innovative solutions like those developed by BioInteractions are pivotal. By integrating cutting-edge antimicrobial and antithrombogenic coatings, BioInteractions is leading the charge in enhancing patient safety, improving implant efficacy, and delivering superior therapeutic outcomes. Surface Active Therapeutics are advanced active treatments which do not need to release their ingredients that are applied directly to the surface of a medical device to help reduce the impact of clinical issues such as thrombosis, Fibrin Sheath Formation or infection. They provide highly effective and sustained protection therapeutic benefits to the patient. They use enhanced materials that form a continuous protective shield over the surface. This shield is made of a polymer matrix, which combines active and passive components to improve the biocompatibility of the implant, enhance the efficacy of the device and elevates the therapeutic benefits to the patient. Recent advancements in Surface Active Therapeutics involve applying effective localised therapeutics to various substrates and geometries, including catheters, drainage systems, ventricular devices, heart valves, and neurological stents. Advanced antimicrobial coatings like BioInteractions’ TridAnt create a continuous protective shield that combines active and passive components to protect against pathogens comprehensively. This matrix ensures a rapid contact-kill mechanism, broad-spectrum efficacy, continuous residual protection, and the ability to disrupt and prevent biofilm growth, effectively combating a wide range of infections for the patient's entire lifetime. These coatings offer the best protection, killing a broad spectrum of pathogens, including bacteria, viruses, fungi, and spores. These include E. coli, MRSA, Influenza, Adenovirus, Norovirus, Clostridium difficile, and SARS-CoV-2. The technology is effective on various geometries and substrates, from soft materials like silicone and fabrics to hard materials like metals (stainless steel and nitinol) and polymers (polyamides, polycarbonates, and polyurethanes). TridAnt is a unique Surface Active Therapeutic that provides a localised effect, making it safe for use throughout the body. It is designed for lifetime efficacy on class 3 implants in chronic areas of the human body. Its polymeric matrix is biocompatible, targeting only microbes (prokaryotic cells) and remaining effective at the local surface to provide sustained efficacy for the patient. This targeted approach enhances safety by avoiding the systemic effects seen with other eluting coatings, which also reduce in efficacy over time. Consequently, TridAnt-coated medical devices maintain a highly effective, fast, durable, and localised protective shield against a broad spectrum of pathogens which disrupts and prevents biofilm throughout the device's lifetime. BioInteractions: Pioneering innovation BioInteractions is at the forefront of innovation in the development of biocompatible coatings for medical devices. Recent surgically implanted devices often require removal, re-insertion, or extensive drug regimens for the patient's lifetime. This has driven the need for coatings that meet both clinical and engineering requirements. Devices like total artificial hearts (TAHs), ventricular assist devices (VADs), vascular stents, and prosthetic mechanical heart valves assist vital organs but face the common challenge of lifetime hemocompatibility, specifically thrombosis. Surface Active Therapeutic technologies offer superior biocompatibility, lifetime antithrombogenicity, and significantly reduce the risk of fibrin sheath formation. BioInteractions developed Astute, an advanced antithrombogenic coating used on chronic, blood-contacting medical implants for over 25 years. Astute combines active and passive components to provide the highest performance and most durable antithrombogenic coating on the market. The active component prevents platelet activation and halts the blood cascade mechanism to inhibit thrombus formation, while the passive components prevent blood components from depositing on the device surface. This multi-faceted approach ensures superior hemocompatibility without compromising performance of the device whilst reducing the risk of clotting over the patient's lifetime. Additionally, the development of miniaturised and minimally invasive procedures presents challenges such as reducing tissue trauma through decreased friction during device insertion and removal. BioInteractions has addressed this challenge by developing Assist, a hydrophilic coating that reduces friction. It is uniquely flexible and durable which enables it to be applied to a wide range of medical devices. Assist fills in surface microstructures, improving the flow of liquids and reducing bodily component deposition and adhesion. This ensures devices remain functional and safe while implanted. Assist is instantly activated through wetting, eliminating the need for pre-soaking and saving preparation time, allowing for straightforward device deployment. Through these innovations, BioInteractions continues to lead the way in enhancing the safety and efficacy of medical devices, improving surgical outcomes, and providing better therapeutic results for patients. Current issues faced by medical product developers Medical product developers and manufacturers navigate a highly regulated environment. Under current European Union (EU) regulations, medical devices are tested by the European Medicines Agency (EMA) following a similar approval processes as pharmaceuticals. BioInteractions' Product Pathway Partnership team works closely with customers to navigate all aspects, including optimising the application process, fixture design, tooling, coating performance testing, regulatory compliance, and providing coating services. This partnership aims to help customers get to market efficiently and effectively with the highest quality coated device.

The future of Surface Active Therapeutics Surface Active Therapeutics promises to revolutionise medical device technology, making implants safer, improving medical implant performance, and enhancing patient safety. Advanced antimicrobial and antithrombogenic coatings, such as TridAnt and Astute, will play a pivotal role. The TridAnt coating provides quick and sustained, broad-spectrum protection against pathogens, ensuring enhanced cleanliness and reducing post-surgical infections, leading to quicker recoveries and fewer complications. Astute combines active and passive antithrombogenic protection which prevents platelet activation and fibrin sheath formation, addressing significant risks associated with blood-contacting implants. This innovation will ensure lifetime antithrombogenicity, enhancing the safety and functionality of devices like heart valves and stents, minimising the need for additional surgeries and long-term medication. Personalised, biocompatible coatings tailored to individual patient needs will further improve outcomes by ensuring optimal performance and minimal adverse reactions. Patients will benefit from improved implant longevity, better therapeutic results, and enhanced quality of life.

It has been a blockbuster year for women’s health as the federal government and medtech place particular focus on the wellbeing of women. At the start of the year, President Joe Biden announced the federal government would focus its health initiatives on improving women’s health outcomes. Since then, his administration has announced two other federal initiatives to improve the care continuum for women. The medical device industry has also had many wins this year for women’s health. Several studies focused on women’s heart health and how TAVI affects them. Some companies launched improved breast cancer locator and imaging systems, and surgical robotics companies started using robots in gynecological procedures. At DeviceTalks West in Santa Clara, California, Oct. 16–17, a wide range of women’s health technologies will be featured. (Learn more about the event and register at West.DeviceTalks.com.) As we enter the last quarter of the year, here are ten women’s health stories that caught the attention of our MassDevice readers: Jill Biden launches $100M initiative to transform women’s health research First Lady Jill Biden and the White House in February announced that $100 million in federal funding will go toward research and development into women’s health. The First Lady said the funding is part of a White House Initiative on Women’s Health Research that the White House announced in November 2023. The Federal Department of Health and Human Services set aside money from the Advanced Research Projects Agency for Health (ARPA-H) for this initiative. ARPA-H’s $100 million funding will go toward early investment in “life-changing” work by women’s health researchers and startup companies. The “Sprint for Women’s Health” initiative will invest in discoveries early when private companies are less likely to take the investment risk. Read the full story here >> Biden signs executive order for women’s health research and innovation President Joe Biden signed an executive order in March that will direct funds and actions toward expanding and improving research on women’s health. Biden’s executive order will create directives that will ensure women’s health is integrated and prioritized across the federal research portfolio and budget, according to the White House. It will also motivate new research on a wide range of topics in women’s health. It also intends to integrate women’s health across the federal research portfolio, prioritize investments in women’s health research, galvanize new research on women’s midlife health and assess unmet needs to support women’s health research. about the administration’s initiatives >> Edwards reports ‘excellent’ outcomes for TAVI in women Edwards Lifesciences announced positive results in August from its RHEIA trial, showing superior outcomes for women who received transcatheter aortic valve implantation (TAVI) over surgical aortic valve replacement (SAVR). The findings involved female patients treated with Edwards’ Sapien 3 and Sapien 3 Ultra valves. The independently-run RHEIA trial included 443 women, aged 73 on average, with severe symptomatic aortic stenosis. One year after treatment, 8.9% of TAVI patients experienced death, stroke, or rehospitalization, compared to 15.6% in the SAVR group, highlighting TAVI’s advantages for this demographic. Edwards continues to focus on improving heart valve replacement outcomes for women. Dr. Hélène Eltchaninoff, a cardiology expert, noted that women are often underrepresented in severe aortic stenosis treatment, emphasizing the significance of this trial’s findings.

The Minneapolis-based company began its ARIA FDA investigational device exemption (IDE) trial to improve outcomes for women undergoing breast reconstruction after mastectomy, enrolling the first patient at University of Utah Health. Melodi has raised $15 million, with Series A funding led by HM Venture Partners, Engage Venture Partners, Southeast Minnesota Capital Fund, and Three Bridges Private Capital. The funds will support clinical activities and further product development for its innovative implantable medical device. The Matrix mesh is an absorbable device that supports soft tissue while releasing antibiotics to reduce post-surgical infections. Co-founder and CEO Sarah Worrell said the device addresses a significant unmet need, as no FDA-approved soft tissue support products with antibiotic properties currently exist for breast surgery. about the fundraising >> Cairn Surgical raises $4.5M for breast cancer locator system Cairn Surgical announced it closed a $4.5 million Series A2 financing round to advance its Breast Cancer Locator (BCL) System. The funds will support completing a U.S. pivotal trial and initiate a limited commercial launch in Europe. The BCL system aims to improve the accuracy of breast-conserving surgeries by providing surgeons with detailed information about the tumor’s size, shape, and precise location. Current tumor localization methods often fail to remove the entire tumor in 20% of cases, leading to additional surgeries. Mick Sawka, investment advisor at Morningside Ventures, which led the funding round, highlighted the system’s promising results in European trials, noting its potential to improve patient care and reduce healthcare costs. Cairn Surgical’s approach is expected to transform the surgical experience for both patients and healthcare providers, he said.

GOTHENBURG, Sweden, Sept. 23, 2024 /PRNewswire/ -- Mölnlycke Health Care partners with Ondine for Steriwave distribution collaboration in the key markets of the UK, Europe and the Middle East. Gothenburg, Sweden 23 September 2024. Mölnlycke® Health Care, a world-leading MedTech company that specialises in innovative solutions for wound care and surgical procedures and Ondine Biomedical Inc. (LON: OBI), a Canadian life sciences company pioneering light-activated antimicrobial treatments, are pleased to announce a strategic partnership to bring Ondine's Steriwave® nasal decolonisation technology to the United Kingdom, EU and Middle East markets. This collaboration marks a significant milestone in the fight against healthcare-associated infections (HAIs) and the growing threat of antimicrobial resistance (AMR), as Steriwave safely reduces hospital infections without generating AMR. Steriwave, a non-antibiotic, light-activated nasal decolonisation therapy, has been clinically proven1-5 to reduce harmful pathogens in the nasal passages, a common source of HAIs and cause of higher rates of mortality, length of stay and readmissions. Mölnlycke's established distribution networks, strong brand and market presence in over 100 countries make it an ideal partner to accelerate the adoption of Steriwave. The first market focus, starting later this year, is the pivotal UK market where Steriwave is already deployed in a number of National Health Service (NHS) Trusts, including, Mid Yorkshire Teaching NHS Trust and Leeds Teaching Hospital NHS Trust. Steriwave is also listed with NHS Supply Chain, a national body that manages the sourcing, delivery and supply of healthcare products to the NHS and healthcare organisations in England and Wales. The UK, with a total addressable market of over 3 million major surgeries annually6 and over 200,000 annual intensive care unit (ICU) admissions,7 has significant global influence in setting best practice for patient care. Mölnlycke will incorporate Steriwave as a key product in its infection control portfolio, enhancing its product offerings with a focus on preventing HAIs and reducing AMR. Distribution will commence in the UK in Q4 2024, followed by expansion into the EU and Middle East regions in 2025, leveraging Mölnlycke's extensive market presence to ultimately broaden the impact of this innovative technology on a global scale. Mölnlycke will spearhead sales and marketing efforts across the UK, EU, and Middle East. Lina Karlsson, Executive Vice President Antiseptics, Mölnlycke, stated: "Mölnlycke's purpose is to revolutionise care for people and planet. In the Antiseptics business area, we do this by making patient skin decolonisation manageable and motivational. We believe that Steriwave can improve the lives of millions of people, fitting perfectly with our purpose and mission. The ability to rapidly eliminate multiple drug-resistant pathogens without generating antimicrobial resistance is key to our sustainability initiative, and complements our Hibiwash® brand skin prep line, enabling us to provide comprehensive 'nose-to-toes' decolonisation prior to surgery. Universal decolonisation is now a well-accepted practice to improve surgical outcomes and produce significant cost savings to healthcare systems." Carolyn Cross, CEO of Ondine Biomedical, commented: "We are excited to be partnering with Mölnlycke Health Care, whose global reach, corporate vision and commitment to sustainable healthcare aligns perfectly with our own core values, purpose and mission. The Mölnlycke collaboration represents a transformative step towards our ambitious plans to combat HAIs and antimicrobial resistance globally. We look forward to working with Mölnlycke in these initial key markets and beyond." HAIs remain a critical challenge across the world, consuming approximately 6% of European public sector budgets8 and resulting in significant costs, avoidable deaths, and human suffering. Post-surgical infections, in particular, extend recovery times and often require prolonged antibiotic treatment, something the UK government is actively seeking to reduce as part of its 5-year action plan for antimicrobial resistance, published in May 2024 9. Nasal decolonisation is recommended in the 2016 WHO Global guidelines for the prevention of surgical site infections10, and the Society for Healthcare Epidemiology of America (SHEA) guidelines, published in May 2023, recommend nasal decolonisation for major surgical procedures11. Steriwave uses a patented light-activated agent to rapidly eliminate infection-causing pathogens in a single, 5-minute treatment. The process works so rapidly that pathogens do not have the opportunity to develop resistance,12 making it an effective alternative to antibiotics. Hospitals using Steriwave have reported high levels of staff and patient compliance. Steriwave has also been proven to be highly effective against drug-resistant pathogens. A 2023 study showed that Steriwave is highly effective (>99.99% kills in 20 seconds) against both moderately drug-resistant (MDR) and extensively drug-resistant (XDR) pathogens.13 For more information, contact: Mathilda Blomsterberg Global Communications Manager Antiseptics, Mölnlycke Tel: +46 737 73 38 14 Email: [email protected] This information was brought to you by Cision The following files are available for download: WANT YOUR COMPANY'S NEWS FEATURED ON PRNEWSWIRE.COM? 440k+ Newsrooms & Influencers 9k+ Digital Media Outlets 270k+ Journalists Opted In GET STARTED
