ABSTRACT:
A balloon for a blood vessel-dilating catheter is fabricated from a biaxially oriented film of an aromatic polyamide or an alloy thereof. The balloon has a calculated modulus of elasticity of from 70 to 190 kg/mm.sup.2. When the balloon is fabricated from an alloy of an aromatic polyamide, the alloy may contain up to 50% by weight of an aliphatic polyamide. The balloon of the invention is soft and flexible as well as dimensionally stable. Therefore, the balloon catheter has a high trackability, and may be inserted into the blood vessel without inducing any injury in the inner surface of the blood vessel. The balloon of the invention also has a good blood compatibility.
