Abstract:
A transmyocardial implant for defining a blood flow pathway directly from a left ventricle through a heart wall to a coronary vessel, the implant comprising:a coronary portion sized to be received within the vessel; a myocardial portion sized to pass through the myocardium into the left ventricle; a transition portion connecting the coronary and myocardial portion for directing blood flow from the myocardial portion and into the coronary portion; at least the coronary portion and the myocardial portion having an open construction for permitting tissue growth across a wall thickness of the coronary portion and the myocardial portion; the myocardial portion including an agent for controlling a coagulation cascade and platelet activation; a porous lining covering the myocardial portion with the porous lining having pores smaller than openings of the open construction of the myocardial portion, the porous lining having a length substantially equal to a width of the heart wall; and the porous lining covering at least the open construction of the myocardial portion but not the open construction of the coronary portion.
