Abstract:
1. A transmyocardial implant for establishing a blood flow path through a heart wall between a heart chamber and a lumen of a coronary vessel comprising: a hollow conduit having an open first end and an open second end, said conduit sized to extend at least from said vessel through said heart wall and into said chamber, said conduit having a conduit wall defining a blood flow pathway within an interior of said conduit between said first and second ends; said first and second ends mutually positioned for said first end to reside within said vessel and opposing a wall of said vessel when said conduit is placed within said heart wall with said second end protruding into said chamber; said conduit wall formed of a material sufficiently rigid to resist deformation and closure of said pathway in response to contraction of said heart wall; a flow restriction formed in said pathway configured to reduce a discharge velocity of blood flow discharged from said first end, the flow restriction defined by a variation in a cross-sectional area of the blood flow defined by the conduit wall.
