Abstract
A loading tool for withdrawing, crimping, and loading a stent-mounted valve into a delivery catheter, and for pushing the stent-mounted valve from the delivery catheter into a native heart valve orifice. The loading tool comprises at least one connector adapted for being removably connected to the stent of the stent-mounted valve. A crimping tool having a generally converging shape is adapted for use with the loading tool. Following connection of the loading tool to the stent-mounted valve, the loading tool operates to allow the stent-mounted valve to be drawn through the crimping tool, and loaded, in a crimped state, into a delivery catheter. Also disclosed is a kit of the of the various components for effecting the delivery of the stent-mounted valve and a method for withdrawing, crimping, and loading a stent-mounted valve from a storage container into a delivery catheter for the performance of a transcatheter valve implantation procedure.

31. A method for withdrawing, crimping, and loading a stent-mounted valve from a storage container into a delivery catheter for the performance of a transcatheter valve implantation procedure, the method comprising:
-
attaching a loading tool to a substantially open state stent-mounted valve inside a storage container using a connector of the loading tool, wherein the connector is configured to be removably connected to the stent-mounted valve, and wherein the loading tool is configured to be coupled to an inner shaft of a delivery catheter; withdrawing the stent-mounted valve from the storage container using the loading tool; advancing the stent-mounted valve through a generally converging-shape crimping tool using the loading tool such that the stent-mounted valve becomes crimped; coupling the loading tool to the inner shaft of the delivery catheter; and retracting the stent-mounted valve and the loading tool into the delivery catheter. - View Dependent Claims (32, 33, 34, 35, 36, 37)
