Abstract: An applicator instrument for dispensing surgical fasteners includes a housing having an actuator and an elongated shaft extending from the housing. The applicator instrument includes a top stamping disposed within the elongated shaft, and a bottom stamping disposed within the elongated shaft that opposes the top stamping. The applicator instrument has a firing system for dispensing at least one surgical fastener from the distal end of the elongated shaft. An end cap is assembled with the distal ends of the top stamping, the bottom stamping, and the elongated shaft for stabilizing the distal end of the applicator instrument. The end cap has a distal end face with castling for engaging an opposing surface such as surgical mesh overlying tissue. The castling prevents the distal end of the applicator instrument from sliding or moving relative to the opposing surface.

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.

Abstract: A dispensing device configured to operate with an adhesive backed mesh and backing film for tissue bonding is disclosed. The dispensing device provides for low-friction, low force pay-out of a desired length of an adhesive backed mesh to a wound site. The device prevents or eliminates distortion of the mesh prior to application to the wound site, and includes means for reducing or eliminating binding during use. The dispensing device is configured to operate in a “forward” mode (substrate to which mesh is applied passes beneath applicator after mesh is applied) to provide essentially an unobstructed view of the wound site during use.

The wound closure device comprises a wound closure strip, the wound closure strip comprising a wound-facing side and a top side, the wound-facing side comprises an adhesive applied over at least a portion of the wound facing side of the wound closure strip and a non-symmetric, two-part release liner assembly detachably adhered to the adhesive, the release liner assembly comprising a first section and a second section with the second section comprising a wound closure strip-free portion forming a tab. In an alternate embodiment, the device is multi-segmented and the wound closure strip may be coextensive with the release liner assembly.

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.

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.
