Devices and Methods for Loading a Prosthesis onto a Delivery System
First Claim
1. A device for loading a prosthesis onto a delivery system, the apparatus comprising:
- a cap having a proximal end, a distal end, and a piston member, the piston member includes a first surface configured to contact a first end of the prosthesis seated therein, the piston member includes at least one side wall extending from a periphery of the first surface, the at least one side wall is configured to contact a portion of the side of the prosthesis seated therein; and
a reducing member having 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.

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.

8. A method for loading a prosthesis onto a delivery system, the method comprising:
-
passing a distal end of a delivery system through a first open end and a second open end of a reducing member, seating the prosthesis in a piston member of a cap by contacting a first end of the prosthesis with a first surface of the piston member and by contacting a portion of a side of the prosthesis with at least one side wall extending from the periphery of the first surface; inserting the distal end of the delivery system into a center of the prosthesis and an opening defined by the piston member; and advancing the cap towards a reducing member such that a portion of the prosthesis seated in the piston member advances along an inner surface of the conical wall of the reducing member. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
