ABSTRACT:
Methods are provided for fully encasing radio-opaque markers in pyrocarbon prosthetic members. Inserts having a pyrolytic carbon portion joined to a radio-opaque marker are affixed to a mandrel surface so that the marker extends thereabove. Pyrocarbon sufficient to encase the marker is deposited on the mandrel, the mandrel is removed, and the deposited layer of pyrocarbon is finished to form the prosthetic member.
