Devices and methods for loading a prosthesis onto a delivery system

摘要

A method for loading a prosthesis onto a delivery system includes passing a distal end of a delivery system through a first open end and a second open end of a reducing member. The method includes 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. Additionally, the method includes inserting the distal end of the delivery system into a center of the prosthesis and an opening defined by the piston member. And the method includes 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.

主权项

1. 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, the reducing member comprising a conical wall, the first open end being configured to receive a piston member of a cap; seating the prosthesis in a recess defined by a first surface and at least one side wall extending from a periphery of the first surface of the piston member of the cap such that a first end of the prosthesis contacts the first surface of the piston member and such that an inner surface of the at least one side wall contacts an outer surface of a portion of a side of the prosthesis; 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 the 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.
