  • Patent number: 11246594
    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.

  • Publication number: 20220031363
    Abstract: A surgical fastener and a related deployment device as well as their methods of use are disclosed. In one embodiment, the deployment device includes one or more surgical fasteners including a head and a distally extending coil body attached to the head. The head includes a through hole with an internal thread. The deployment device also includes a mandrel including a threaded portion located at a distal end of the mandrel. The threaded portion is engaged with the internal thread of the one or more surgical fasteners. A rotator is associated with the one or more surgical fasteners such that the rotator can selectively rotate the one or more surgical fasteners relative to the mandrel to displace the one or more surgical fasteners in a distal direction.

  • Publication number: 20220031308
    Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.

  • Publication number: 20210369265
    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.

  • Patent number: 11103238
    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: 20210161528
    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: 11007044
    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: 20210085324
    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.
