Angioplasty and related medical dilatation balloons are molded from a polyurethane in which the "soft" segment is a minor segment by weight and the "hard" segment is the major segment by weight and which polyurethane has a hardness of at least 75D and a glass transition temperature of more than about 38.degree. C. The balloons can be integrally molded on one end of a catheter fabricated from the above type of polyurethane. Alternatively, the balloon is formed from polyurethane of the above type and the catheter is formed from elastomeric polyurethane and like polymers commonly employed in preparation of catheters. The balloon is then bonded to the catheter by conventional procedures.
