Abstract:
An apparatus for controlling a direction of formation of a hole through a myocardium for subsequent placement into said hole of a myocardial portion of a transmyocardial implant where 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 comprising:A. a narrow, elongated base member havinga. a base surface for placement against an epicardial surface of a heart adjacent a coronary vessel having a vessel axis;b. a determinable base axis extending parallel to a longitudinal axis of said base member for placement of the base surface on the epicardial surface with the base axis parallel with the vessel axis by placement of said base member on said epicardial surface adjacent to said vessel;B. a straight and rigid myocardial penetrator;C. a support member for supporting the straight and rigid myocardial penetrator for movement along a straight 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;D. the support member secured to the base member with the support axis and base axis defining a support angle and with said base member extending from a side of said support member for said support member and base member to define a substantially L-shaped configuration; andE. the support angle and the implant angle being supplementary angles.
