Abstract
Abstract The present invention relates to a balloon catheter having a balloon which is produced by molding polyarylenesulfide or an alloy thereof wherein polyarylenesulfide is a main constituent. Said balloon is provided with excellent dimensional stability as well as sufficient softness and flexibility, leading to an improved trackability of the catheter to reach the target lesion.
