  • Patent number: 10687804
    Abstract: An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft, and an elongated conduit extending through the elongated shaft. A firing system is disposed within the housing. The firing system has an insertion tool having a top surface that extends proximal and distal ends thereof and a stripper ramp that projects above the top surface. An actuator activates the firing system to commence a firing cycle. During the firing cycle, the firing system drives the insertion tool toward the distal end of the elongated shaft. The elongated conduit has a top wall with a top notch formed therein. The stripper ramp slides through the top notch for guiding movement of the insertion tool as the firing system drives the insertion tool toward the distal end of the elongated shaft.

  • Patent number: 10675015
    Abstract: A system for deploying a suture implant includes a delivery device and a suture implant coupled with the distal end of the delivery device. The suture implant includes a suture and a slip knot that defines a suture loop, the slip knot defining a dynamic end of the suture loop that is located opposite a closed end of the suture loop. The suture implant includes a tissue anchor having first and second openings, whereby the closed end of the suture loop passes through the first and second openings for securing the tissue anchor to the suture loop. A tensioner is secured to the first end of the suture, and a pledget, located between the tensioner and the tissue anchor, is secured to the second end of the suture. Pulling the tensioner away from the tissue anchor slides the pledget and the slip knot toward the tissue anchor for shortening the length of the suture loop and reducing the distance between the pledget and the tissue anchor.

  • Patent number: 10675020
    Abstract: An applicator instrument for dispensing surgical fasteners includes a handle and an articulating shaft extending from the handle including proximal and distal shaft sections and an articulating joint interconnecting the proximal and distal shaft sections. The proximal shaft section has a proximal outer tube and a proximal inner member, and the distal shaft section includes a distal outer tube and a distal inner member. An incompressible member interconnects the proximal and distal inner members to form an inner shaft member having a fixed length. Distal movement of the proximal outer tube relative to the proximal inner member articulates the distal shaft section relative to the proximal shaft section via the articulating joint. As the articulating shaft moves between a straight configuration and an articulated configuration the distance between a distal-most end of the distal outer tube and the handle changes while the length of the inner shaft member remains fixed.

  • Patent number: 10568627
    Abstract: A surgical fastener includes a first leg having a first distal barb and a first proximal barb that extend inwardly, and a second leg having a second distal barb and a second proximal barb that extend inwardly. A bridge interconnects proximal ends of the first and second legs. A first distance between opposing inner tips of the first and second distal barbs is greater than a second distance between opposing inner tips of the first and second proximal barbs. The first leg tapers inwardly between the proximal and distal ends thereof and has a cross-sectional area that is greater at the proximal end than at the distal end. The second leg tapers inwardly between the proximal and distal ends thereof and has a cross-sectional area that is greater at the proximal end than at the distal end. An insertion tool engages a crown on the proximal side of the bridge.
