Abstract:
A transmyocardial implant for establishing a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vessel residing on an exterior of said wall, said implant comprising:a hollow rigid conduit having a rigid and non-expansible first portion and a rigid and non-expansible second portion coupled to one another;said first portion sized to be received within said lumen, said first portion having an axial dimension adapted to be aligned with an axis of said vessel;said second portion sized to extend from said vessel through said myocardium into said chamber;said conduit having open first and second ends on axial ends of respective ones of said first and second portions to define a blood flow pathway within an interior of said conduit between said first and second ends; andsaid first portion and second portion are disposed at an angle relative to one another and with said first portion having a base opposing said second portion, said base having an axially extending hole extending substantially through an axial length of said base for blood to flow radially through said axially extending hole in addition to flowing axially out of said first open end,a cylindrical wall of said first portion other than said base being substantially solid;said second portion having a solid wall blocking fluid flow through said second portion between said blood flow pathway and said myocardium throughout an entire thickness of said myocardium.
