Patent ID: 8512281

Claim:
An angioplasty balloon comprising a polymer mixture comprising a polyamide and from 10 to 90% by weight of an elastomeric material, characterized in that said elastomeric material comprises a polyamide-based polymer obtained from the polymerization of a compound forming polyamide blocks that is selected from the group consisting of an aminocarboxylic acid of Formula (1) and a lactam of Formula (2): with a polyether diamine triblock compound of Formula (3): and a dicarboxylic acid of Formula (4): HOOC—(R3) m -COOH (4) wherein the groups R1, R2 and R3 are each binding groups comprising a hydrocarbon chain therein that may be interrupted by one or more amide groups; x is an integer from 1 to 20; y is an integer from 4 to 50, z is an integer from 1 to 20; m is 0 or 1; wherein the angioplasty balloon is provided on a catheter, and wherein the angioplasty balloon is configured for inflation and deflation during an angioplasty operation.
