1. A device for loading a prosthesis onto a delivery system, the apparatus comprising:
- a cap comprising a proximal end, a distal end, and a piston member, the piston member comprising a first surface configured to contact a first end of the prosthesis seated therein and at least one side wall extending from a periphery of the first surface, the first surface and the at least one side wall defining a recess for seating the prosthesis therein, the at least one side wall being configured to contact a portion of the side of the prosthesis seated within the recess; and
a reducing member comprising a conical wall, a first open end, and a second open end, the first open end is configured to receive the piston member,wherein the reducing member reduces an external dimension of at least a portion of the prosthesis seated in the piston member as the prosthesis is moved along an inner surface of the conical wall.
