Abstract

In various embodiments, a surgical catheter is provided. The catheter may comprise one or more hydrophobic barrier layers made from an ethylene-pertfluoroethylenepropylene (“EFEP”) copolymer. Additionally, the catheter may comprise another polymer layer made from a reactive polar polymer. In at least one embodiment, the reactive polar polymer may be a modified-poly(ether block amide) (“PEBA”) copolymer, such as an amine-terminated PEBA. Moreover, in various embodiments, a composition is provided that may comprise a reactive polar polymer bonded to an EFEP copolymer.
