Balloon catheter comprises a shaft having a proximal end, a distal end, and an inflation lumen extending therein, and a balloon on the shaft which has an interior in fluid communication with the inflation lumen. The balloon is formed of a blend of polymeric materials comprising a transparent amorphous nylon having a Shore D duromcter hardness of not less than 77D and being not more than about 40% by weight of the blend, and a polyamide or a polyether block amide having a Shore D duromcter hardness of no more than 73D. An increase in radial diameter of the balloon above nominal pressure for one atmosphere of pressure is no greater than 0.025 mm/atm. A guidewire catheter is also provided. |
