1. An apparatus for radially expanding a prosthetic device in a conduit or orifice of a human body, the apparatus comprising:
- an expansion device having a main axis and an outer mounting surface for mounting the prosthetic device in a crimped state thereon,wherein the expansion device is configured to expand radially outwards from a first configuration to a second configuration to expand the prosthetic device to an expanded shape having a non-circular cross-sectional profile perpendicular to the main axis of the expansion device.

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.
