SYSTEM AND METHOD FOR CRIMPING A PROSTHETIC VALVE
First Claim
1. A crimping device for crimping a radially expandable and compressible prosthetic valve, the crimping device comprising:
- a housing configured to receive a prosthetic valve in a radially expanded state, the housing member including a funnel segment and an outlet in communication with the funnel segment; and
an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.

Abstract
Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.

10. A crimping device for crimping a radially expandable and compressible prosthetic valve, the crimping device comprising:
-
a housing having an outlet, the housing member configured to receive a prosthetic valve in a radially expanded state; a pusher member that is axially movable relative to the housing, wherein the pusher member is configured to abut an end of the prosthetic valve and axial movement of the pusher member relative to the housing causes radial compression of the prosthetic valve and axial movement of the prosthetic valve through the outlet in a radially compressed, delivery configuration; and an actuator that is rotatable relative to the housing and the pusher member to cause axial movement of the pusher member relative to the housing. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for crimping a prosthetic valve, the method comprising:
-
rotating an actuator of a crimping device relative to a housing of the crimping device, wherein the housing includes a funnel in communication with an outlet of the crimping device; and slidingly engaging the prosthetic valve with the funnel such that at least a portion of the prosthetic valve compresses radially and exits the crimping device via the outlet. - View Dependent Claims (17, 18, 19, 20)
