ABSTRACT:
The invention relates to a method of increasing flexibility of joints between areas of plastic materials, and in particular the joint between a catheter shaft and a balloon neck involving welding the overlapping portions to create a joint region and applying a tensile force to the joint region, the force being of sufficient strength to elongate the joint region, thus thinning the joint region.
