PTFE and ePTFE offer medical device manufacturers a range of
benefits for their finished products. Using the material as a
filtration media, it is ideally suited to several application
areas, such as in drug delivery, urine collection, and
laparoscopic surgery. This article reviews the properties of the
material and the specific advantages of using it in filter
applications. Eric C. Wigner was formerly a market specialist

identify safe and effective filtration solutions for critical
healthcare applications. The use of expanded
polytetrafluoroethylene (ePTFE) membranes is a desirable option
for designers and engineers looking to optimize flow and
retention characteristics. PTFE and ePTFE—A Quick Primer
Polytetrafluoroethylene (PTFE) is a polymer consisting of a
carbon backbone covalently bonded to a uniform sheath of
fluorine atom
