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.

Abstract: A surgical instrument including a power assist device, and its method of use for deploying surgical fasteners, is disclosed. The surgical instrument may include a handle, an elongated shaft extending from the handle, and a surgical fastener deployment system including a driveshaft. The driveshaft is actuatable between at least a first proximal position and a second distal position. A striker is movable relative to the driveshaft and an impact surface is associated with the driveshaft. The impact surface is constructed and arranged to be struck by the striker member to displace the driveshaft to the second distal position and deploy the surgical fastener.

Abstract: Embodiments of a surgical instrument and its methods of use are disclosed. The disclosed embodiments of a surgical instrument may include a handle and an elongated shaft assembly distally extending from the handle. The elongated shaft assembly may include an articulable portion. An articulation control may be associated with the elongated shaft assembly. The articulation control may be movable between a first position in which the elongated shaft assembly is arranged in a first articulation position and a second position in which the elongated shaft assembly is arranged in a second articulation position. The surgical instrument may include a fastener deployment system with a locking member. The articulation control may block movement of the locking member when the articulation control is located in the first position. The articulation control may also permit movement of the locking member when the articulation control is located in the second position.

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.

Abstract: Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft assembly extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft assembly including a reciprocating driveshaft disposed within the elongated shaft assembly. The driveshaft may include an internal channel and at least one guide surface shaped and arranged to maintain an orientation of at least one fastener in the channel of the driveshaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft assembly for displacing one or more fasteners within the elongated shaft assembly towards a distal fastener deployment position.

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.

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.

Abstract: A surgical instrument and its method of use are disclosed. In one embodiment, the surgical instrument may include a handle and an elongated shaft assembly extending distally from the handle. The elongated shaft assembly may include an articulable portion with an articulation direction. The elongated shaft assembly may also include a tubular member with a flexible portion with a preferential bending direction and a direction of bending resistance. The tubular member may permit articulation of the elongated shaft assembly when the preferential bending direction is aligned with the articulation direction.
