ABSTRACT:
An apparatus controls a direction of formation of a hole through a myocardium for subsequent placement into the hole of a myocardial portion of a transmyocardial implant. The implant also includes a coronary portion having a coronary axis set at an implant angle to a myocardial axis of the myocardial portion. The apparatus includes a base member having base surface for placement against an epicardial surface of a heart adjacent a coronary vessel having a vessel axis. The base member has a determinable base axis for placement of the base surface on the epicardial surface with the base axis parallel with the vessel axis. A support member supports a myocardial penetrator for movement along a support axis in a line of travel parallel to the support axis and substantially restricting the myocardial penetrator from movement transverse to the support axis. The support member is secure to the base member with the support axis and base axis defining a support angle. The support angle and the implant angle are supplementary angles.
