Block copolymer elastomer catheter balloons
 Balloons for medical devices, particularly balloon angioplasty catheters, which have hybrid compliance curves are made from particular block copolymer thermoplastic elastomers. Melt blends of an engineering resin having by a flexural modulus of about 240,000 psi or greater and a block copolymer elastomer having a flexural modulus of about 150,000 psi or less, the block copolymer including at least one block which is structurally similar to the engineering resin are also used to produce medical device balloons.
