         6 . The wound closure device of  claim 1 , wherein the at least one protrusion comprises at least one barb extending away from a body of the plurality of fixation components. 
     
     
         7 . The wound closure device of  claim 1 , further comprising:
 an adhesive positioned on the biocompatible material between the rigid deployment plate and the biocompatible material to thereby removably couple the rigid deployment plate to the biocompatible material.   
     
     
         8 . The wound closure device of  claim 1 , wherein each of the plurality of fixation components are configured to allow a suture to be connected to and extend from the second end of each of the plurality of fixation components in a direction away from each of the plurality of fixation components. 
     
     
         9 . The wound closure device of  claim 1 , wherein the plurality of fixation components each include an axial hole extending from the first end to the second end for accepting a suture. 
     
     
         10 . The wound closure device of  claim 1 , further comprising a suture embedded in the second end of each of the plurality of fixation components. 
     
     
         11 . The wound closure device of  claim 1 , wherein each of the plurality of fixation components is connected to the biocompatible material at a periphery of the biocompatible material. 
     
     
         12 . The wound closure device of  claim 1 , wherein the biocompatible material comprises an inner portion surrounded by an outer portion, wherein the plurality of fixation components extend through the outer portion. 
     
     
         13 . The wound closure device of  claim 12 , wherein the inner portion comprises a first material, and wherein the outer portion comprises a second material that is different than the first material. 
     
     
         14 . The wound closure device of  claim 12 , wherein the rigid deployment plate is removably disposed over the inner portion of the biocompatible material such that the rigid deployment plate does not extend into the outer portion, wherein the rigid deployment plate is configured to shield the portion of biocompatible material covered by the rigid deployment plate from contacting the tissue surface before the wound closure device is properly positioned with the tissue surface, and wherein the rigid deployment plate is configured to be removed from the biocompatible material when the wound closure device is properly positioned with respect to the tissue surface such that the biocompatible material can be brought into abutment with the tissue surface to affix the wound closure device to the tissue surface. 
     
     
         15 . The wound closure device of  claim 1 , further comprising a suture connected to the second end of the each of the plurality of fixation components such that the suture is fixedly attached to each of the plurality of fixation components. 
     
     
         16 . The wound closure device of  claim 1 , further comprising one or more vertically extending components extending away from the rigid deployment plate, wherein the one or more vertically extending components are used to pull the rigid deployment plate off of the biocompatible material when the wound closure device is properly positioned. 
     
     
         17 . A method of closing a wound in a tissue, the method comprising:
 positioning the wound closure device of  claim 1  into abutment with an interior surface of the tissue at a location of the wound.   
     
     
         18 . The method of  claim 17 , further comprising:
 removing the rigid deployment plate from the biocompatible material; and   applying a force to the wound closure device such each of the plurality of fixation components pierce the interior surface of the tissue, thereby affixing the wound closure device to the interior surface of the tissue.   
     
     
         19 . The method of  claim 18 , wherein at least a portion of the biocompatible material comprises an adhesive material, the method further comprising:
 bringing the adhesive material into abutment with the interior surface of the tissue.   
     
     
         20 . The method of  claim 18 , further comprising:
 threading a suture through the tissue from the interior surface of the tissue to an exterior surface of the tissue at the location of the wound prior to applying the force to the wound closure device; and   tightening the suture of each of the plurality of fixation components to thereby close the wound.   
     
     
         21 . The method of  claim 20 , wherein the step of applying a force to the wound closure device such that each of the plurality of fixation components pierce the interior surface of the tissue comprises applying tension to the suture connected to and extending through each of the plurality of fixation components.
