Medical device balloons containing thermoplastic elastomers
First Claim
1. A dilatation balloon for use in a medical catheter device, said dilatation balloon comprising a thermoplastic elastomer in a blend with a non-compliant structural polymeric material wherein said blend is a homogeneous blend and comprises a ratio of about 30:
- 70 to about 60;
40, thermoplastic elastomer to non-compliant structural polymer.

Abstract
A dilatation balloon and catheter for insertion into a bodily conduit. The catheter (10) includes shaft (12) and a dilatation balloon (24) at the distal end of the shaft. The balloon is inflated via a central lumen (14) in the shaft for delivery of a fluid inflation media. The balloon is fabricated from a combination of a thermoplastic elastomer (TPE), preferably an engineering thermoplastic elastomer (ETE), with a non-compliant structural polymeric material. The combination may be a blend of the non-compliant structural polymer and the TPE. Alternatively, the combination may be a layered balloon having, for example, a non-compliant structural polymer inner layer and a soft, abrasion resistant, elastomeric outer layer. Methods for fabricating the balloon from the combination of a TPE and a non-compliant structural polymer are also disclosed.
