Expandable member for deploying a prosthetic device

摘要

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.

主权项

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.
