Abstract

Disclosed herein are embodiments of a balloon shaped to have one or more enlarged recons to selectively increase expansion forces on an implant. For example, the balloon may have a central portion that is enlarged to exert more force on the center of a stent-mounted prosthetic heart valve. This overcomes the stent-mounted prosthetic heart valve's tendency to expand with flared ends. This forms a more cylindrical or barrel shaped stent frame during expansion of the balloon—reducing or eliminating the instance wherein the cylindrical stent frame has flared ends. Alternatively, the balloon may have conical flares placed to cause or enhance flared ends of the cylindrical implant to enhance its anchoring capabilities.
