Sharp edged device for closing wounds without knots
First Claim
1. A device for closure of a living tissue wound, comprising:
- a resiliently flexible and fusible collar having a C-shaped side profile disposed about a central region extending along a central axis, the C-shaped collar extending circumferentially between two end portions, the collar biasable into a nominally closed O-shape so that the end portions overlap, the overlapping end portions adapted to be fused together upon application of sufficient energy to at least one of the overlapping end portions, wherein at least one of the end portions of the collar has a sharp edge, wherein the sharp edge of the end portion is more rigid than the remaining portions of the collar prior to the end portions being fused.

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.

16. A method for closing a living tissue wound comprising
providing a resiliently flexible and fusible collar having a C-shaped side profile disposed about a central region extending along a central axis, the C-shaped collar extending circumferentially between two end portions, wherein at least one of the end portions of the collar has a hardened sharp edge for tissue penetration; -
forcing the sharp edge of the collar through the living tissue in a first direction adjacent one of edge of the wound;
forcing the sharp edge of the collar through the living tissue in a second direction, generally opposite the first direction, adjacent another edge of the wound, such that at least a portion of the two edges forming the tissue wound are positioned within the central region of the C-shaped collar;
biasing the collar into a nominally closed O-shape so that the end portions of the collar overlap and the tissue edges within the central region of the collar are substantially joined to close the tissue wound; and
applying sufficient energy to the overlapped end portions of the collar so as to fuse the overlapped portions of the collar and maintain the closed wound. - View Dependent Claims (17, 18, 19)
