What is Pretreatment? Pretreatment for PTFE coating is the preparation of metal surfaces for application of PFOA-free PTFE coatings. This is an essential step in the production process, as it allows the coating to properly adhere to the metal surface. This helps prevent against the flaking of coatings, which can lead to serious problems, such…

Micron-accurate Coating Equal to Medical Device Tolerances With most biomedical procedures, success is measured in fractions of an inch–more commonly, microns. Exact friction-free insertion of guidewires, hypotubes, catheters, cannulas, stents, balloons, drug-delivery catheters, cameras, and tissue samplers is critical to the success and safety of every procedure. PTFE-coated guidewires are often used in the first…

Recall is the last word a biomedical business wants to hear. But that is what struck the guidewire industry last year after a voluntary recall – that the FDA classified as Class 1– for stainless steel guidewires going back to April 2013. The problem was poor adhesion of an aqueous PFOA-free PTFE coating that resulted in flakes…

Why the Solution to PTFE Adhesion to Guidewires is Not a Material Swap As seen in Q-Med The demand by the EPA that manufacturers eliminate PFOA from their PTFE formulations by 2015 appears related to a series of crises for some medical manufacturers due to loss of coating adhesion on guidewires. A recent FDA Class I recall notice states: “There…

Initiation into the medical device industry for Orion Industries (Chicago) came in the form of a VHS tape. In the late 1970s, the company was contracted by medical manufacturer Baxter to develop a coating for early endoscopic instruments that provided permanent electrical insulation. New to the medical device industry, Orion required a better understanding of the finished…
