  • Patent number: 10368870
    Abstract: A surgical fastener is provided for various surgical fastening applications, including attaching an implantable prosthesis, such as a soft tissue repair fabric, to tissue and/or muscle. The surgical fastener may include a coil body and a head attached to the coil body. The head may include at least one external thread adapted to engage with a corresponding internal thread of a delivery device. The head may include a through hole adapted to receive a rod therethrough for guiding and/or driving the surgical fastener from the delivery device. The through hole may have a non-circular configuration that complements at least a portion of the shape of a non-circular rod. The coil body may also define a channel with a non-circular configuration. The non-circular through hole and/or channel may be engaged and rotated by the non-circular rod to rotate the surgical fastener for delivery and insertion of the fastener into the prosthesis and/or tissue.

  • Patent number: 10363030
    Abstract: A surgical fastener is provided for various surgical fastening applications, including attaching an implantable prosthesis, such as a soft tissue repair fabric, to tissue and/or muscle. The surgical fastener may include a coil body and a separate head that is attached to the coil body. The head may include two or more radial wings extending in an outward radial direction from the head body. Each wing may include an external thread to engage with a corresponding internal thread of a delivery device. Each wing may be spaced from an adjacent wing by an opening therebetween to receive a drive member for driving the surgical fastener. The coil body may be attached to the center of the head. A proximal-most coil of the coil body may be spaced from a distal face of the head to form a gap therebetween.

  • Publication number: 20190223870
    Abstract: A surgical fastener deployment system may include a plurality of coil fasteners having a head and coil body. In one embodiment, the head may be larger in diameter than the coil body. The fasteners may also be mounted on a guide rod or mandrel that passes through a through-hole of the head and the coil body. The shaft may also include a guiding element that contacts and stabilizes the coil body as the fastener is deployed from a distal end of the shaft. When the head approaches and contacts the guiding element, the guiding element may deflect to permit the head to pass.

  • Publication number: 20190209147
    Abstract: Articulating surgical instruments are disclosed. In one embodiment, a surgical instrument may include an elongated shaft assembly including an articulable portion moveable between a non-articulated configuration and an articulated configuration. First and second articulating shafts of the elongated shaft assembly may be coaxially arranged and axially fixed at an attachment point located distally from the articulable portion. Proximal portions of the first and second articulating shafts may be displaceable in opposing directions to articulate the articulable portion from the non-articulated configuration to the articulated configuration. In another embodiment, an articulation control may be movable from a first position to a second position to move an articulation lock from a locked configuration to an unlocked configuration to selectively permit articulation of a surgical instrument. The articulation lock also may be movable from the second position to a third position to articulate the surgical instrument.

  • Publication number: 20190209170
    Abstract: Surgical fasteners for use with articulating surgical instruments are disclosed. In one embodiment, a surgical fastener may include a head, a shaft extending distally from the head, and a through bore extending through the shaft from a proximal surface of the head to a distal end of the shaft. A fastener carrier of a surgical instrument may be slidably received in the through bore, and the through bore may be sized and shaped to have two or fewer contact points with the fastener carrier when the fastener carrier is in a fully articulated configuration. In another embodiment, a fastener may include a head, a shaft extending distally from the head and including a distal tip, a sloped surface sloping toward the distal tip, and a through bore passing through the head, shaft, and sloped surface. The sloped surface may terminate at two shoulders located on opposing sides of the through bore.

  • Patent number: 10335139
    Abstract: An instrument for delivering a suture transfascially may include a handle, a shaft extending from the handle, and a pair of needles that are moveable to an extended position beyond the end of the shaft. One or more sutures are carried by the instrument and may be delivered transfascially. A transfascial suture assembly includes a suture having a first segment, a second segment, and an intermediate segment therebetween. A force distributing member is locatable at the intermediate segment. Suture retainers may be provided at the end of each suture segment, and may have a connection that is moveable relative to the portion of the suture segment connected therewith. A method of delivering transfascial sutures includes inserting a twin-needle instrument loaded with one or more sutures into an abdominal cavity and deploying, from within the abdominal cavity, the suture carrying needles through a soft tissue repair patch and then through at least part of the abdominal wall.

  • Publication number: 20190076229
    Abstract: The present invention is an implantable adhesive mesh prosthesis for reinforcing and/or repairing a defect in tissue that is easy to roll into a small diameter cylinder or other low-profile shape for passing through a trocar, incision, or other surgical instrument. More specifically, the adhesive may be applied to the mesh material in a pattern that leaves a significant portion of the surface area of the mesh material free of adhesive. In one embodiment, the adhesive is applied only near the outer perimeter of the mesh product. In another embodiment, the adhesive is applied in spots over all or a portion the surface of the mesh product. In yet another embodiment, the adhesive is applied in parallel lines on the surface of the mesh product and the mesh may be rolled up around an axis parallel to the lines of adhesive.

  • Publication number: 20190069888
    Abstract: Embodiments of a surgical instrument including an actuation lockout system as well as its method of use are disclosed. In one embodiment, a surgical instrument includes a trigger and a driveshaft coupled to the trigger such that actuation of the trigger causes the driveshaft to move from a first position to a second position, thereby resulting in deployment of a surgical fastener. An actuation lockout system restrains distal movement of the driveshaft until a force greater than or equal to a threshold force is applied to the trigger.
