<p>A marking device (1) intended primarily for marking an anastomosis site of a coronary artery graft. The marking device comprises a generally annular body (12) having a circumferential opening (15) between two spaced apart ends (13, 14) of the body. The body is resiliently flexible in construction so that the opening (15) can be expanded to facilitate placement of the body on the grafted artery at or near the anastomosis site. The body is radiopaque so that it can be located using radiographic procedures.</p> |
