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: The present invention is directed to apparatus and method for forming balloons with improved dimensional stability and balloons formed by the same. The method of the present invention provides for a very accurate control of the temperature profile of the balloon material during its making. The attributes of the balloon can be affected by how the balloon is treated during the blowing stage and after the initial blowing, i.e., heat-setting. Using the present method, the balloon will form more uniformly and evenly (e.g., wall thickness and outer diameter of the balloon). The present method significantly increases the dimensional stability of the balloon which provides a balloon that is more predictable in use. The present heat-set process also provides the means for the working length to be located more accurately on dilation catheters and stent delivery systems.
