Abstract
In an embodiment, a device for loading a prosthesis onto a delivery system comprises a cap and a reducing member. The cap has a piston member that seats a prosthesis. The piston member has at least one side wall configured to contact a portion of the side of the prosthesis seated therein. The reducing member has a conical wall, a first open end, and a second open end. The first open end is configured to receive the piston member. 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.
Claims12
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.
