Expandable member for deploying a prosthetic device
First Claim
Patent Images
1. A method for deploying an expandable heart valve in a patient, the method comprising:
- introducing a guide wire into a patient and advancing the guidewire through a vasculature of a patient to a deployment site;
advancing over the guidewire an elongate shaft having a guidewire lumen therethrough and having an expandable heart valve coupled to a plurality of struts disposed on a distal end thereof, the plurality of struts, when in a collapsed position, are disposed substantially axially to the elongate shaft;
positioning the heart valve at the deployment site; and
rotating a screw mechanism, causing the plurality of struts to expand radially into an expanded configuration, thereby deploying the heart valve 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.

4. A method for delivering a prosthetic heart valve device through the vasculature of a patient comprising:
-
providing an expandable member at a distal end of an elongate shaft, the expandable member having a plurality of struts that form an open frame configuration; coupling the prosthetic heart valve to the plurality of struts; and expanding the expansion device from a first configuration to a second configuration to expand the prosthetic heart valve by rotating a screw mechanism, causing the plurality of struts to expand radially into the second configuration. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
