Expandable member for deploying a prosthetic device
First Claim
Patent Images
1. An apparatus for delivering a prosthetic device through the vasculature of a patient comprising:
- an elongate shaft having a distal end;
a radially expandable member coupled to the distal end of the elongate shaft, the expandable member comprising a distal end portion and a proximal end portion that are movable relative to one another between a first orientation and a second orientation; and
a plurality of struts coupled to at least one of the distal end and proximal end portions and having a prosthetic device receiving area,wherein in the first orientation the distal end and proximal end portions are a first distance apart, and in the second configuration the distal end and proximal end portions are a second distance apart, the second distance being less than the first distance, andwherein movement of the distal end and proximal end portions from the first orientation to the second orientation causes connecting members to expand radially outwards from a first configuration to a second configuration to expand the prosthetic device,wherein one or more of the plurality of struts extend from the distal end portion to the proximal end portion,wherein the expandable member comprises a cover that at least partially surrounds the plurality of struts, andwherein the cover is configured to open to permit fluid to flow through the expandable member from the distal end portion to the proximal end portion and to close to substantially prevent fluid from flowing through the expandable member from the proximal end portion to the distal end portion.

Abstract
An apparatus 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.
