Abstract
A prosthetic implant delivery assembly includes a prosthetic implant including an expandable stent and a catheter for delivering the prosthetic implant. The expandable stent includes apices circumferentially-spaced apart relative to each other. At least some of the apices include an aperture disposed therein. The catheter includes arms disposed at an end of a shaft, and the arms are moveable between a radially compressed state and a radially expanded state via a sheath. The arms each include a hook portion for releasably engaging the apertures of the apices. The arms are configured to move from the radially compressed state to the radially expanded state when the plurality arms is exposed from within the sheath such that the hook portion disengages from the apices of the prosthetic implant and releases the expandable stent from the catheter.
