ABSTRACT:
A bypass conduit having a desired hollow internal geometry for defining a bounded blood flow path from an open first end positioned in a heart chamber and an open second end connected to a lumen of a coronary vessel is made by forming a master having an external surface with an external geometry complementary to the desired internal geometry of the conduit. The external surface of the master is coated with pyrolytic carbon to define a pyrolytic carbon conduit of pyrolytic carbon bonded to the external surface of the master and with the pyrolytic carbon having an internal surface with a conduit geometry complementary to the external geometry of the master. The master is removed from the pyrolytic carbon conduit.
