Vascular conduit device and system for implanting

摘要

The present invention provides a vascular conduit device including a deformable flange and complementary securing ring in cooperation for securing the device within an aperture defined in a tissue wall. The present invention further provides a system for implanting such a vascular conduit device in a tissue wall. More specifically, the present invention provides a system including a coring device for defining an aperture in a tissue wall (such as a ventricle and/or a blood vessel) and securely implanting a vascular conduit device therein so as to provide fluid communication between a first and second surface of the tissue wall via the vascular conduit device.

主权项

1. A system for implanting a vascular conduit device, the system comprising:
a coring device for defining an aperture in a tissue wall having a first tissue surface and a second tissue surface, the coring device defining a lumen adapted to receive a guide for directing the coring device to the second tissue surface; an articulating device for selectively deploying through the tissue wall and proximate the first tissue surface, the articulating device adapted to provide counter-traction for advancing the coring device into the tissue wall and to selectively occlude the aperture; a sutureless conduit device for lining the aperture and maintaining fluid communication between the first and second tissue surfaces of the tissue wall, the sutureless conduit device adapted to be separably positioned over and coaxial with the coring device and to be advanced over the coring device and into the aperture, the sutureless conduit device comprising a tube having proximal and distal ends, and inside and outside surfaces, the inside surface of the tube adapted to slidably contact an outer surface of the coring device when the sutureless conduit device is positioned over the coring device; and a delivery device for selectively deploying the sutureless conduit device into the aperture, the delivery device comprising a plurality of retractor arms adapted to engage the tissue wall and to provide counter-traction for advancing the sutureless conduit device into the aperture.
