Abstract
An inflatable member suitable for angioplasty or other medical procedures comprising asymmetric conic shoulder portions that optimize the wrapped profile. The asymmetry distributes the inflatable member material of the shoulder portions over a larger area to reduce the inflatable member profile and improve flexibility. Optionally, the asymmetrical shoulder portions preformed creases to facilitate folding. In an alternate embodiment, each shoulder portion has at least three radially spaced preformed creases to optimize folding in the shoulder portion. The invention also comprises methods of forming such inflatable members, the methods generally comprising using molds having the requisite characteristics. Specifically, the mold may have ridges within the areas corresponding the shoulder portions to form the preformed creases when the inflatable member is blow molded.
