Building a Defensible Antimicrobial Claims Strategy for 510(k) Clearance

Medical device manufacturers developing antimicrobial technologies often prioritize early efficacy data as a primary development milestone. While antimicrobial performance is essential for 510(k) clearance, strong results alone do not automatically translate into a claim that will withstand regulatory scrutiny. As Aaron Strickland, Vice President of Research and Development at iFyber, emphasizes,…

Advancing Dental Material Biofilm Testing with High-Throughput In Vitro Assays

For teams developing dental and implant materials, biofilm performance is a defining factor in clinical success, regulatory acceptance, and product differentiation. The challenge is not in understanding biofilms, but generating reliable, clinically relevant data that reflects how microbial communities interact with material surfaces under real-world conditions. Traditional antimicrobial testing approaches often fall…

Managing Antimicrobial Resistance in Chronic Wound Care

Slow-healing wounds, like diabetic foot ulcers, venous leg wounds, and pressure ulcers, frequently turn into long-term battles. When dealing with chronic wounds, treatment can be difficult to target due to a multitude of complicating factors. Diabetes, vascular disease, and immune suppression all reduce the body’s ability to fight infection and…

Biofilm Disruptors in Wound Care Products: Moving Beyond Antimicrobials

Since the 1940s, antimicrobials have been our first line of defense in wound care. However, the very thing that has helped us fight infections is now starting to help the infections fight back. Structured communities of microorganisms, like bacteria, fungi, or yeast—called biofilms— are significantly more tolerant to antimicrobial treatments…

Biofilm Testing: The Critical Step in Advancing Infection-Resistant Medical Devices

Infections related to medical devices remain a persistent and costly challenge in modern healthcare. Despite the advancement of antimicrobial materials and design innovations, biofilm formation continues to undermine the efficacy of many devices – contributing to patient complications, prolonged hospital stays, and increased clinician workload. Biofilm formation on medical devices remains a…
