Abstract
Abstract A balloon catheter having an inflatable balloon in which the outer surface of the inflatable balloon is surrounded by an elastomeric sleeve. The sleeve is attached throughout at least a majority of its area to the balloon outer surface to provide pin hole and abrasion resistance. Preferably, the inflatable balloon is made of a flexible material of less elasticity than the material of the elastomeric sleeve. Thus the balloon expands to a generally limited maximum transverse dimension, while the collapse of the balloon is facilitated by the elastomeric sleeve.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A balloon catheter, which comprises a flexible, elongated member, an inflatable balloon carried on the elongated member to define an inflation chamber within said balloon, and an inflation conduit extending along said member and communicating with the inflation chamber, said inflatable balloon being surrounded by an elastomeric sleeve to provide pinhole and abrasion resistance to said balloon, said balloon and sleeve being together defined by a coextruded tube, said balloon being made of a flexible, relatively inelastic, biaxially oriented material selected from the group consisting of PET and nylon.
Claim 2
Dependent Claim
