Abstract
A device including a self-locking suture including both a braided section and a monofilament section is provided. The monofilament includes a single strand. The braided section includes three or more strands that are intertwined or woven together. The terminal end of the braid is compressible to take on a radially expanded configuration. The braided structure is temporarily fixable in the open configuration providing a wide berth opening. A needle at the terminal end of the monofilament is insertable through the wide berth opening and pushed out through the back wall of the expanded braid, after which the braid can be pulled on to collapse it down onto the barbed monofilament. The construct may then be tightened onto the tissues to be joined, and the one-way locking mechanism between the braided trap and the directionally biased suture automatically engages. Another aspect includes a method of fastening tissue using the device.
