ABSTRACT:
Disclosed is an elongate suture having a longitudinal axis, a needle end, a latch collar end, and a node for interacting with the latch collar end. The node lays laterally on the elongate suture transverse to the longitudinal axis and has a proximal and a distal edge with respect to the needle end. In the invention, a portion of the node's proximal edge is perpendicular to the elongate suture's longitudinal axis thus acting to prevent forward movement after the suture has been placed. Between the proximal and distal edges of a single notch is a top surface. This top surface will usually be planar or convex. In one embodiment of the device, the elongate suture has multiple nodes. The nodes are then spacedly positioned along the longitudinal axis of the suture cord, thus forming notches between the nodes. These notches are sized in relation to the collar to allow it to move along the longitudinal surface when the stitched tissue moves.
