Surface modification of expanded ultra high molecular weight polyethylene(eUHMWPE) for improved bondability

摘要

A balloon catheter and a method of making the balloon catheter, having a balloon which is bonded to an elongated shaft, and which has a first layer and a second layer and an improved bond between the balloon and the shaft. One aspect of the invention is directed to a balloon in which the balloon first layer includes eUHMWPE and has at least a section that has been oxidized with a chromic acid solution to provide improved bondability.
