Marker members of radiopaque material in the form of bands each of a different geometric configuration are sutured to the point at which a surgical graft to a blood vessel is made as in a coronary bypass operation. These ring or other shaped radiopaque members provide markers identifying the exact coronary blood vessel that the graft will lead to, each geometrical shape identifying a different coronary vessel bypassed, thus facilitating bypass graft catherization by identifying the entry point of any specific bypass graft.

A surgical procedure for radiographically identifying each site and destination of a surgical bypass graft comprising the steps of: providing a plurality of marker members in the form of bands of a radiopaque material, each of said marker members having a different geometrical configuration, each of such configurations adapted to identify a different preselected graft destination, placing each of said differently geometrically configured marker members around a different graft section at the site of the origin of the graft which its configuration is adapted to identify, and suturing said markers in place at said graft sites to identify each such destination by virtue of the different geometrical configuration of each of said marker members.
