  • Publication number: 20140213966
    Abstract: A medical device includes an elongated body including an outer surface having a plurality of barbs extending therefrom and an inner surface defining a lumen therethrough. The elongated body includes at least one channel extending through the inner surface and the outer surface, the channel defined between an inner surface of one of the plurality of barbs and a cut outer surface of the elongated body. A wound treatment material is disposed within the lumen of the elongated body. The barb is configured to move between a first position to close the channel and retain the wound treatment material within the lumen and a second position to open the channel and permit the release of the wound treatment material therethrough.

  • Patent number: 8617206
    Abstract: Biocompatible wound closure devices including an elongate body and a plug member are useful for wound repair. A wound closure device includes an elongate body defining a longitudinal axis and having a proximal end and a distal end, and a plug member having a tissue facing surface and including a first shaped section and a second shaped section, each of the first and second shaped sections having an abutment surface. The first and second shaped sections are movable about a hinge between a collapsed position in which the abutment surfaces extend away from the longitudinal axis of the elongate body and a deployed position in which the abutment surfaces abut and are substantially aligned with the longitudinal axis of the elongate body, the abutment surfaces controlling a deployed angle of the tissue facing surface of the plug member with respect to the elongate body.
