摘要:
Catheters, balloons, and methods of manufacturing balloons for balloon catheters using lasers are disclosed. A catheter with a shaft sized for use with a 0.014 inch guide wire includes a polymeric balloon having a body portion with an inflated outer diameter of more than 6 millimeters. An inflatable balloon includes an inflated outer diameter to inner waist diameter ratio of 12.5 to 1. An inflatable polymeric balloon that has a body portion with two regions that have different molecular orientations is also provided. A method of processing an elongate polymeric material includes heating a portion of the polymeric material with a laser while longitudinally stretching the portion of the polymeric material. A method of manufacturing a balloon includes heating and longitudinally stretching a first and second portion of an elongate polymeric tube to form first and second end portion. The remaining body portion is radially expanded to form the balloon.
