Abstract
A transmyocardial implant delivery system is disclosed 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 the heart. The transmyocardial implant delivery assembly includes as conduit for defining a blood flow path, a temporary sheath, and a tool holding a second end of the conduit. The conduit includes a rigid portion adapted to be inserted into and retained within the heart wall of a heart chamber. The rigid conduit is sufficiently rigid to withstand collapsing in response to contraction forces of the heart wall. The conduit also includes a synthetic flexible portion that is in fluid communication with the rigid portion. An end of the flexible portion corresponding to the second end of the conduit is sized to be received in a lumen of a coronary vessel. The transmyocardial implant delivery system is inserted through the heart wall. After insertion the second end of the conduit is communicated with a lumen of a coronary vessel. The sheath can then be removed leaving the conduit in place within the heart wall.
