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.

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.

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: 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: Various embodiments of a non-deforming surgical fastener are discussed. In one embodiment, the fastener includes two legs and a backspan extending between the two legs. The fastener also includes a backspan thickness that is adapted to reduce the pressure and/or increase the holding strength applied to underlying materials. The non-deforming fastener is constructed and arranged to retain substantially the same shape before, during and after deployment into the target implantation site.
