System for loading a collapsible heart valve
First Claim
1. An assembly for loading a self-expanding prosthetic device into a delivery device, comprising:
- a compression member having a longitudinal axis, a first open end with a first diameter, a second open end with a second diameter less than the first diameter, and a wall decreasing in diameter in a distal direction from the first open end towards the second open end, the wall defining an open space adapted to receive the prosthetic device; and
a support member coupleable to the compression member, the support member and the compression member being movable relative to one another between an initial position in which the support member is relatively far from the first open end of the compression member and an operative position in which a base of the support member is relatively close to the first open end of the compression member, wherein movement of the support member and the compression member from the initial position to the operative position pushes the prosthetic device at least partially through the open space.

Abstract
An assembly for collapsing a self-expanding prosthetic heart valve includes a compression member, a support member and a constricting member. The compression member has a tapered wall between its first open end and its second open end, the tapered wall defining an open space adapted to receive the valve. The support member has a base and a recess adapted to receive an end of the valve. The support member and the compression member are movable toward one another to compress the valve and push it through a relatively small aperture in the second open end of the compression member. The second end of the constricting member is sized to receive the compressed valve from the second open end of the compression member for loading into a delivery device.
