摘要：
A loading assembly for crimping and loading a prosthetic heart valve into a delivery device includes a loading base, a base funnel, and a compression member. The loading base has a support and a body extending from the support with a recess defined within the body. The recess is configured to receive a substantial portion of the annulus section of the heart valve in an at least partially collapsed condition. The base funnel is configured to be coupled to the loading base and to at least partially collapse the annulus section of the heart valve as it is inserted into the recess in the loading base. The compression member is configured to be coupled to the loading base with the heart valve inserted in the recess for further collapsing the heart valve and loading it into the delivery device.
