A surgical fastening apparatus including at least one self-closing clip and a deployment device. The self-closing clip comprises a wire defining an intermediate portion interconnecting opposing, first and second side portions having a memory set loop shape. The deployment device includes a clip hold
A surgical fastening apparatus including at least one self-closing clip and a deployment device. The self-closing clip comprises a wire defining an intermediate portion interconnecting opposing, first and second side portions having a memory set loop shape. The deployment device includes a clip holding assembly and an actuator. The clip holding assembly includes first and second containment arms and a transfer rod. The containment arms have a distal segment defining a lumen extending from an open, distal end. The transfer rod is associated with at least one of the containment arms in an axially movable fashion and forms an engagement feature. The actuator is connected to the transfer rod for controlling movement of the rod. Upon final assembly in a pre-deployment state, the engagement feature of the transfer rod engages the intermediate portion of the clip, and the side portions are captured by the containment arms.
1. A surgical fastening apparatus comprising: at least one self-closing clip comprising a wire defining an intermediate portion interconnecting opposing, first and second side portions, the side portions each having a memory set loop shape; anda deployment device comprising: at least one clip holdin
1. A surgical fastening apparatus comprising: at least one self-closing clip comprising a wire defining an intermediate portion interconnecting opposing, first and second side portions, the side portions each having a memory set loop shape; anda deployment device comprising: at least one clip holding assembly for selectively retaining and deploying the clip, the clip holding assembly including: first and second hollow containment arms each forming a distal segment defining a lumen extending from an open, distal end, wherein the containment arms are arranged in a side-by-side fashion,a first transfer rod associated with at least one of the containment arms in an axially movable fashion relative to a longitudinal axis of the at least one containment arm, wherein a distal region of the transfer rod forms an engagement feature,an actuator connected to the transfer rod for controlling movement of the transfer rod relative to the containment arms;wherein upon final assembly in a pre-deployment state, the engagement feature of the transfer rod engages the intermediate portion of the clip, and the first and second side portions of the clip are captured by the distal segments of the first and second containment arms;and further wherein the deployment device is configured such that upon actuation of the actuator, the transfer rod extends distally relative to the containment arms in transitioning to a deployment state in which the first and second side portions of the clip extend distally beyond the distal end of the first and second containment arms, respectively. 2. The fastening apparatus of claim 1, wherein the containment arms each form a side aperture extending from the distal end and open to the corresponding lumen, the aperture sized to slidably receive the intermediate portion of the clip. 3. The fastening apparatus of claim 2, wherein upon final assembly, the aperture of the first containment arm faces the second containment arm, and the aperture of the second containment arm faces the first containment arm. 4. The fastening apparatus of claim 1, wherein the first transfer rod is slidably disposed within the first containment arm, the clip holding assembly further comprising: a second transfer rod slidably disposed within the second containment arm. 5. The fastening apparatus of claim 4, wherein the engagement feature of each of the transfer rods includes a tubular body forming a passage sized to receive a respective one of the side portions of the clip, and an axial slot formed in the tubular body and providing exterior access to the passage. 6. The fastening apparatus of claim 5, wherein the engagement feature further includes a notch formed contiguous with the slot and sized to receive the intermediate portion of the clip. 7. The fastening apparatus of claim 6, wherein upon final assembly, the notch of the first transfer rod is circumferentially aligned with the aperture of the first containment arm such that upon final assembly in the pre-deployment state, the first side portion of the clip is disposed within the passage of the first transfer rod and the lumen of the first containment arm, and the intermediate portion of the clip extends from the first containment arm via the notch of the first transfer rod and the aperture of the first containment arm. 8. The fastening apparatus of claim 4, wherein the clip holding assembly further comprises: a shaft interconnecting the first and second transfer rods; anda conduit from which the containment arms distally extend;wherein the shaft is slidably disposed within the conduit. 9. The fastening apparatus of claim 1, wherein the transfer rod is disposed between the first and second containment arms. 10. The fastening apparatus of claim 1, wherein the fastening apparatus includes a plurality of the clips and the deployment device includes a plurality of the clip holding assemblies selectively retaining respective ones of the clips. 11. The fastening apparatus of claim 10, wherein the clip holding assemblies are arranged in a circumferential manner relative to one another. 12. The fastening apparatus of claim 11, wherein the deployment device further comprises: a valve sizing rod disposed within the circumferentially arranged clip holding assemblies, the valve sizing rod configured to selectively alter a diameter collectively defined by the clip holding assemblies. 13. The fastening apparatus of claim 11, wherein the deployment device further comprises: a plurality of valve holding mechanisms associated with the plurality of clip holding assemblies. 14. The fastening apparatus of claim 13, wherein the valve holding mechanisms each include a holding member slidably disposed within a hollow cylinder. 15. The fastening apparatus of claim 14, wherein a distal region of each of the holding members has a memory set curve shape and terminates at sharpened, distal end. 16. The fastening apparatus of claim 14, wherein respective ones of the valve holding mechanisms are circumferentially interposed between the clip holding assemblies. 17. The fastening apparatus of claim 10, wherein the actuator includes a first control device connected to the transfer rods and a second control device connected to the containment arms of each of the plurality of clip holding assemblies, and further wherein the deployment device is constructed such that the first control member is slidable relative to the second control member in effectuating substantially simultaneous deployment of the clips. 18. The fastening apparatus of claim 10, wherein the actuator includes a source of hydraulic fluid remotely connected to the clip holding assemblies via tubing. 19. The fastening apparatus of claim 1, wherein the actuator includes opposing handle bodies each connected to a corresponding lever, and further wherein the levers are connected to the transfer rod.
