Abstract

The present disclosure provides a deployment system that includes (a) an elongate shaft having a first end and a second end, (b) a grasping assembly coupled to the first end of the elongate shaft including a first jaw and a second jaw rotatable with respect to the elongate shaft, (c) an actuator coupled to the second end of the elongate shaft and configured to move the grasping assembly between an open position and a closed position, and (d) a wound closure device configured to be positioned between the first jaw and the second jaw, wherein the wound closure device comprises at least two tacks connected to and extending therethrough, wherein each of the first jaw and the second jaw include at least one pin configured to be removably positioned in an axial hole extending through a respective tack when the wound closure device is coupled to the grasping assembly.

1 . A deployment system, comprising:
 an elongate shaft having a first end and a second end;   a grasping assembly coupled to the first end of the elongate shaft, wherein the grasping assembly includes a first jaw and a second jaw rotatable with respect to the elongate shaft;   an actuator coupled to the second end of the elongate shaft, wherein the actuator is configured to move the grasping assembly between an open position and a closed position; and   a wound closure device configured to be positioned between the first jaw and the second jaw, wherein the wound closure device comprises at least two tacks connected to and extending therethrough, wherein each of the first jaw and the second jaw include at least one pin configured to be removably positioned in an axial hole extending through a respective tack of the at least two tacks when the wound closure device is coupled to the grasping assembly, and wherein the at least one pin extending from the first jaw and the at one pin extending from the second jaw do not overlap when the grasping assembly is in the closed position.   
     
     
         2 . The deployment system of  claim 1 , wherein the wound closure device includes a biocompatible mesh. 
     
     
         3 . The deployment system of  claim 2 , wherein the biocompatible mesh comprises a microreplicated mesh. 
     
     
         4 . The deployment system of  claim 2 , wherein the mesh comprises a multilayer mesh, wherein at least one layer of the multilayer mesh comprises a microreplicated material. 
     
     
         5 . The deployment system of  claim 1 , wherein each of the at least two tacks comprises at least one protrusion configured to penetrate a tissue surface. 
     
     
         6 . The deployment system of  claim 5 , wherein the at least one protrusion comprises at least one barb extending away from a body of the tack. 
     
     
         7 . The deployment system of  claim 1 , wherein each pin has a greater length than each of the at least two tacks, such that an end of the pin extends beyond an end of the tack when coupled thereto. 
     
     
         8 . The deployment system of  claim 7 , wherein the end of the pin that extends beyond the end of the tack includes a tapered end configured to penetrate a tissue surface. 
     
     
         9 . The deployment system of  claim 8 , wherein the tapered end includes three cutting edges. 
     
     
         10 . The deployment system of  claim 1 , wherein the first jaw and the second jaw comprises a hole configured to receive a pin of a respective tack connected to the wound closure device. 
     
     
         11 . The deployment system of  claim 1 , wherein the first jaw and the second jaw comprises a first magnet configured to attract a second magnet of a respective tack connected to the wound closure device. 
     
     
         12 . The deployment system of  claim 1 , further comprising a release mechanism configured to release the at least two tacks coupled to the respective at least one pin on each of the first jaw and the second jaw when the wound closure device is coupled to the grasping assembly. 
     
     
         13 . The deployment system of  claim 1 , wherein each of the first jaw and the second jaw rotate with respect to the other. 
     
     
         14 . The deployment system of  claim 1 , wherein each of the first jaw and the second jaw comprises a proximal jaw segment and a distal jaw segment, wherein the distal jaw segment is rotatable with respect to the proximal jaw segment. 
     
     
         15 . A method of closing a wound in a tissue surface, the method comprising:
 bringing the deployment system of  claim 1  adjacent to the tissue surface;   with the grasping assembly in the open position, bringing the wound closure device into abutment with the tissue surface; and   bringing the grasping assembly into the closed position around a portion of the tissue surface such that the at least two tacks pierce the tissue surface, thereby affixing the wound closure device to the tissue surface.   
     
     
         16 . The method of claim  21 , wherein bringing the grasping assembly into the closed position around the portion of the tissue surface causes the at least one pin of each of the first jaw and the second jaw to pierce the surface tissue. 
     
     
         17 . The method of  claim 1 , wherein each of the at least two tacks comprises at least one protrusion configured to penetrate a tissue surface. 
     
     
         18 . The method of  claim 17 , wherein the at least one protrusion comprises at least one barb extending away from a body of the tack. 
     
     
         19 . The method of  claim 15 , wherein each pin has a greater length than each of the at least two tacks, such that an end of the pin extends beyond an end of the tack when coupled thereto. 
     
     
         20 . The method of  claims 19 , wherein the end of the pin that extends beyond the end of the tack includes a tapered end configured to penetrate a tissue surface.
