Abstract
An balloon catheter is provided with an improved neck portion. The neck portion of the balloon is used to attach the end of the balloon to a catheter. Before attaching the balloon to the catheter, the neck portion is lengthened and thinned out to make the neck portion more flexible. Heat shrink tubing may be used to apply pressure to the neck portion to force the material of the neck portion to flow along a mandrel inserted into the neck portion.
