Microplastics in Infusion Bags
Microplastics have become a pressing topic in environmental and health discussions, with increasing attention from the media and scientific community. These tiny plastic particles, typically defined as ranging in size from 1 micrometer to 5 millimeters, can be composed of various types of polymers and are now being detected in an array of consumer products. A recent […]
Ensuring Trustworthy Third-Party Lab Data for Regulatory Success
Companies regularly rely on third-party laboratory testing data to support regulatory medical device and pharmaceutical submissions, particularly when lacking in-house expertise or facilities. The credibility of these third party laboratories is crucial to regulatory success, but recent actions by the FDA highlight the risks associated with unvetted or noncompliant third party data. Escalating FDA Scrutiny […]
Thoughtful Design in Surgical Lighting: Balancing Usability, Durability, and Sustainability
Traditional headlamps (worn above) are cumbersome and don’t accommodate face shields. A groundbreaking surgical task light has been introduced by MezLight in collaboration with Syensqo[1], demonstrating a thoughtful approach to product design by considering key factors such as: Customer needs Sustainability concerns Environmental durability Material suitability Addressing Customer Needs: Enhanced Usability and Safety Traditional surgical […]
Celebrating Rubber Band Day
Every year on March 17th, we commemorate the invention of the rubber band, patented by Stephen Perry in 1845. This innovation followed Charles Goodyear’s groundbreaking discovery in 1838 that adding sulfur to polyisoprene creates crosslinks, significantly enhancing its elastic properties. This breakthrough led to the development of rubber tires. Composition of Rubber Bands Rubber bands […]
FDA Layoffs: Impact on Medical Device Review and Patient Safety
Over the February 15-16, 2025 weekend, the new U.S. administration laid off a substantial number of FDA reviewers from the Center for Device and Radiological Health (CDRH), the branch that reviews the safety and efficacy of new medical devices, including hip and knee implants, cardiovascular and respiratory devices, ophthalmological treatments, wound care, and thousands of […]
Quantifying Rapid Rheological Changes
Blood vessel with hemostatic agent In the world of material science and product design, understanding and measuring rheological transitions is crucial across many industries. These changes in the rheological properties, which can be triggered by stimuli such as motion, light, heat, electrical and magnetic fields, or chemical interactions, play a significant role in the successful […]
FDA’s Regulatory Freeze: Implications for Medical Device Standards and Patient Safety
Medical device development relies heavily on standards to ensure patient safety, efficacy, and regulatory compliance. Organizations such as ASTM, AAMI/ISO, and USP establish critical test methods to ensure adequate cleaning and sterility, mechanical performance, biocompatibility, and material integrity. These standards streamline innovation while safeguarding patients, reducing redundant testing, and maintaining U.S. competitiveness in global markets. […]
