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