Abstract
A conduit is provided to provide a bypass around a blockage in the coronary artery. The conduit is adapted to be positioned in the myocardium or heart wall to provide a passage for blood to flow between a chamber of the heart such as the left ventricle and the coronary artery, distal to the blockage. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. Various attachment means are provided to anchor the stent and prevent its migration. In one embodiment, a conduit is provided having a distal top which is more preferably a ball top, wire top, flare top or flip-down top. These top configurations anchor the shunt at one end in the coronary artery.
Claims17
A conduit for providing a passageway of blood between a chamber of the heart and an adjacent blood vessel, comprising:
- an elongate body having a first end and a second end and a lumen extending therethrough;
- and
- a top that is collapsible into a first configuration and expandable into a second configuration, the top when expanded being sized and configured to hold the top within the blood vessel,
- wherein the top comprises a flip-down top, and
- wherein the body and the top form a substantially T-shaped configuration when the top is in the second configuration.
A conduit for providing a passageway of blood between a chamber of the heart and an adjacent blood vessel, comprising:
- an elongate body having a first end and a second end and a lumen extending therethrough;
- and
- a top that is collapsible into a first configuration and expandable into a second configuration, the top when expanded being sized and configured to hold the top within the blood vessel,
- wherein the top further comprises a plurality of tab-like sections configured to fold down relative to the elongate body so as to form a substantially T-shaped configuration.
