EXPANDABLE MEMBER FOR DEPLOYING A PROSTHETIC DEVICE
First Claim
Patent Images
1. A method for deploying an expandable prosthetic device in a patient, the method comprising:
- positioning an expandable prosthetic device in a crimped state over a plurality of struts of an expandable member in a collapsed configuration, the plurality of struts extending longitudinally in an open-frame configuration, the expandable member disposed on a distal end of an elongate shaft;
advancing the shaft through a vasculature of a patient to position the prosthetic device at a deployment site; and
rotating a screw mechanism to shorten the expandable member longitudinally, causing the plurality of struts to expand radially into an expanded configuration, and urging the prosthetic device into an expanded state and deploying the prosthetic device.

Abstract
An apparatus and method for delivering a prosthetic device through the vasculature of a patient includes a radially expandable member coupled to the distal end of an elongate shaft. The expandable member has an open frame configuration and an outer mounting surface for mounting the prosthetic device in a collapsed state thereon. The expandable member expands radially outwards from a first configuration to a second configuration to expand a prosthetic device mounted thereon.
