Abstract

A dry valve crimping and loading system includes packaging, a crimper disposed in the packaging, and a dry valve prosthesis disposed within a crimper chamber of the crimper. The crimper chamber has a first volume in an expanded state a second volume in a collapsed state, wherein the first volume is greater than the second volume. The crimper is configured to transition the dry valve prosthesis from an uncompressed state to a compressed state when the crimper chamber transitions from the expanded state to the collapsed state to expel the glycerol from the dry valve prosthesis as the crimper transitions the dry valve prosthesis from the uncompressed state to the compressed state.

Claims (11)

1 . A method for crimping and loading a dry valve prosthesis onto a delivery system with a dry valve crimping and loading system, wherein the dry valve crimping and loading system includes a rinse tray, a crimper disposed within the rinse tray, and the dry valve prosthesis pre-loaded within a crimper chamber of the crimper, the method comprising:

at least partially filling the rinse tray with a rinse solution;

actuating the crimper to transition the crimper chamber from an expanded state to a collapsed state and to compress the dry valve prosthesis to expel glycerol from the dry valve prosthesis;

releasing or disengaging the crimper to transition the crimper chamber from the collapsed state to the expanded state;

removing the crimper and the dry valve prosthesis from the rinse tray;

disposing a distal end of a delivery system within the dry valve prosthesis;

actuating the crimper to transition the crimper chamber from the expanded state to the collapsed state and to transition the dry valve prosthesis from an uncompressed state to a compressed state onto the distal end of the delivery system;

coupling the dry valve prosthesis to the delivery system;

removing the crimper from the dry valve prosthesis and the delivery system; and

sterilizing the delivery system and the dry valve prosthesis.

2 . The method of claim 1 , wherein the crimper of the dry valve crimping and loading system includes a handle, wherein actuation of the handle transitions the crimper chamber from the expanded state to the collapsed state and the dry valve prosthesis from the uncompressed state to the compressed state.
