Abstract

A device for closure of a living tissue wound without requiring knots. The device is a resiliently flexible and fusible collar having a C-shaped side profile disposed about a central region extending along a central axis. The collar extends circumferentially between two end portions for containing at least a portion of two tissue edges forming a tissue wound. The collar is biasable into a nominally closed O-shape so that the end portions overlap and tissue edges therein are joined together to close the tissue wound. The overlapping end portions are adapted to be fused together upon application of sufficient energy to the overlapping end portions to maintain the tissue edges in a joined position. The collar has a width greater than a thickness of the collar to increase the area of fusion between the overlapping end portions. In addition, at least one of the end portions of the collar has a sharp edge for tissue penetration so that the collar can be used to close open tissue wounds.
