摘要：
An assembly (200) for collapsing a self-expanding prosthetic heart valve (100) includes a compression member (202), a support member (204), a constricting member (300), and a spacer (270) which may be used for smaller sized heart valves. The compression member has a tapered wall (206) between its first open end and its second open end, the tapered wall defining an open space adapted to receive the heart valve. The support member has a base (220) and a recess (226) adapted to receive an end of the heart valve. The support member and the compression member are movable toward one another to compress the heart valve and push it through a relatively small aperture (218) in the second open end of the compression member. The second end (306) of the constricting member is sized to receive the compressed heart valve from the second open end of the compression member for loading into a delivery device (10).
