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 steal-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 steel-mounted valve from a storage container into a delivery catheter for the performance of a transcatheter valve implantation procedure.

47. A loading system for loading a valve prosthesis into a delivery catheter, the loading system comprising:
-
a loading tool comprising a loading tool connection member, wherein the loading tool connection member comprises a first plurality of prongs, wherein the loading tool connection member includes an open state with the first plurality of prongs flared outwardly and a closed state with the first plurality of prongs radially contracted; a valve prosthesis including a radially compressed configuration and a radially expanded configuration, the valve prosthesis comprising valve prosthesis connection members configured to removably engage with a respective one of the first plurality of prongs, wherein the loading tool is configured to engage valve prosthesis with the valve prosthesis in the radially expanded configuration and the loading tool in the open state; and a crimping tool comprising a proximal end and a distal end, wherein the diameter of the distal end is greater than the diameter of the proximal end, wherein the loading tool connection member in the open state engaged with the valve prosthesis in the radially expanding configuration is configured to pass through the crimping tool such that the valve prosthesis crimps from the radially expanded configuration to the radially compressed configuration and the loading tool connection member radially contracts from the open state to the closed state. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
