Abstract: The invention is directed to adjustable length mold assemblies for forming inflatable members and methods for using adjustable length mold assemblies for forming inflatable members, such as, for example, balloons for use with balloon catheters and stent delivery systems. The adjustable length mold assemblies comprise at least two mold pieces adapted to fit together, one mold piece having a surface configured to be slidably received by a bore of the other mold piece, the placement of one piece within the other defining a chamber of variable length which forms the mold. Each adjustable length mold assembly of the present invention is effective to form balloons, where if desired different balloons formed by a single mold may have different lengths. The adjustable length mold assemblies may also comprise a positioner to put a mold piece in a desired position relative to the other, and a locking mechanism to secure a mold piece in a desired position.

Abstract: A balloon catheter with a balloon having first and second tapered sections adjacent the distal and proximal ends of the working length of the balloon, respectively, and third and fourth tapered sections adjacent the first and second tapered section, respectively. The first and second tapered sections taper at a first angle to a smaller outer diameter than the inflated outer diameter of the working length inflated within a deployment range of the balloon, and the third and fourth tapered sections taper at a second angle larger than the first angle. The balloon has expandable retention sections proximal and the distal to the working length of the balloon for inhibiting migration of a stent mounted on the balloon.
