Abstract
A balloon catheter comprises a flexible, elongated member, an inflatable balloon carried on the elongated member to define an inflated chamber within the balloon, and an inflation conduit extending along the member and communicating with the inflation chamber. The inflatable balloon, in turn, defines a wall which comprises at least three bonded layers. A first pair of the layers comprises a flexible plastic material which is typically a condensation polymer. A second of the layers comprises a flexible polymer which is typically a vinylic polymer which is covalently bonded to the first layers and positioned between them.
