Abstract
A system for expanding a device in a conduit or orifice of a human body includes a balloon member that is movable from a first configuration to a second configuration. External surfaces of the balloon member can collectively have a non-cylindrical cross-section relative to a main axis of the balloon member, such that the external surfaces of the balloon member generally conform to the anatomical shape of the conduit or orifice when the balloon member is in the second configuration.
