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.
