System and method for crimping a prosthetic valve
First Claim
1. A system comprising:
- a radially expandable and compressible prosthetic valve;
a crimping device positioned around the valve, the crimping device being configured to reduce the diameter of the valve to a delivery configuration; and
a sterile package enclosing the valve and the crimping device.

Abstract
An exemplary system for crimping a prosthetic valve comprises a radially expandable and compressible prosthetic valve, a crimping device positioned around the valve and configured to reduce the diameter of the valve to a delivery configuration, and a sterile package enclosing the valve and the crimping device. The valve can be pre-assembled in a partially crimped configuration within the crimping device. After removing the sterile packaging, the crimping device can be used to crimp the valve from the partially crimped configuration to the delivery configuration, such as by twisting a knob on the crimping device. The system can further comprise at least a portion of a delivery catheter within the sterile package, wherein the valve is pre-mounted on or adjacent to an inflatable balloon of the delivery catheter, such that the valve can be crimped onto the delivery catheter using the crimping device.

21. A valve crimping device, comprising:
-
a radially compressible collet configured to receive a prosthetic valve, the collet comprising a first axial end portion, an opposing second axial end portion, and an intermediate portion between the first and second axial end portions, the first and second axial end portions each being tapered from a greater outer diameter adjacent to the intermediate portion to a lesser outer diameter proximate the respective axial ends of the collet; and a mechanism for radially compressing the collet in order to crimp the valve onto a delivery catheter. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
