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.

1-13. (canceled)
A tissue implant device for implantation into ischemic tissue comprising:
- an implant having a first configuration with a first profile and a second configuration having a second profile that is greater than the first profile whereby surrounding tissue into which the implant is placed in stress and is irritated sufficiently to cause an injury response including thrombosis formation that initiates angiogenesis;
- the implant comprising a plurality of expandable members each having a free end and an end joined to the implant, each member configured to diverge away from a substantially common central longitudinal axis of the implant during self-expansion from the first configuration to the second configuration.

A method for placing a conduit in the wall of a patient's heart to establish a blood flow path between a coronary vessel and a heart chamber, the method comprising steps of:
- (a) positioning a guide member that extends through the coronary vessel and the heart wall into a heart chamber;
- (b) using the guide member to deliver a conduit into the heart chamber;
- and
- (c) positioning the conduit in the heart wall to establish a blood flow path between the heart chamber and the interior of the vessel;
- wherein the conduit is covered by a sheath, and further comprising covering at least a portion of the conduit while placing the conduit in the heart wall and then removing the sheath.
