Abstract

This is a balloon catheter having braided layer which extends generally from the proximal end of the catheter to a location distal of the balloon. In particular, it is desirable that the shaft of the catheter proximal of the balloon be stiffest at the proximal section and least stiff just proximal of the balloon. Although the catheter may be a single lumen catheter using some type of a core wire to act as a valve for inflation and deflation of the balloon, it is within the scope of the invention to include either a separate inflation/deflation lumen or one incorporated into the various concentric polymeric layers used to make up the proximal shaft. Particularly preferred is the use of an elastic, compliant balloon.
