Abstract: A surgical marker/connector can be provided in the form of a ring made of a fluoroscopic material, including a shape memory alloy such as NITINOL. The ring preferably includes a plurality of small suture attachments in the form of loops that are disposed on the periphery of the ring and which lie in a plane that includes the ring itself. The loops are large enough to receive sutures which, in turn, can be used to connect the ring to a portion of a patient's body, or to connect separate portions of a patient's body to each other using the marker/connector as an intermediate connector. If the ring is made of a shape memory alloy, the ring can be wrapped tightly about an elongate member such as a mandrel, which than can be inserted into the patient's body through a trochar or cannula. After insertion, the ring will change temperature and resume its original configuration where it can be sutured in place as desired.
