Abstract: The present invention is an anchor for a thermally responsive ligature that deforms when heated. The ligature has an engaging segment for engaging the anchor with two clamping portions and a curved portion. The anchor is made from a thermally and/or electrically conductive material and has an engaging surface for engaging a curved portion of the ligature. The clamping portions of the engaging segment of the ligature pass between the body and the clamping component when the curved portion of the engaging segment is engaging the engaging surface of the anchor body. Then, portions of the clamping component can be moved towards the anchor body to reconfigure the clamping component so that the portions of the clamping component press the clamping portions of the engaging segment of the ligature against the anchor body and maintain the engaging segment of the ligature in thermal or electrical communication with the anchor body.

Abstract: An apparatus and method for connecting two tubular vessels together in a side-by-side or tangential manner is disclosed. The apparatus has an annulus and at least one series of fingers connected to and extending away from the annulus. Each finger is preferably heat-formed into an arcuate shape. In use, a deployment apparatus is used to constrain the fingers of the apparatus to be in a relatively planar configuration. The deployment apparatus containing the apparatus is placed between and in contact with the two tubular vessels so that one tubular vessel is above the device and one tubular vessel is below the device and so that the fingers of the device come into contact with the tissue of the vessels. As the fingers penetrate the vessels the constraint on the fingers is removed so that the fingers can assume their unbiased, heat-formed arcuate shape. In this way, the fingers penetrate and grasp the tissue of the vessels so that the apparatus grasps the vessels and pulls the vessels toward each other.
