A surgical system comprising: an anchor; and an introducer provided to deliver the anchor into tissue; wherein the anchor includes a body having a pointed leading end that is configured to pierce the tissue, a plurality of spines projecting radially away from the body having a width and a height configured to allow the spines to engage with the tissue, an eyelet attached to a trailing end of the body, and a length of suture attached to the eyelet; wherein the introducer includes a cannula, the cannula having a pointed distal end, an opening formed in the cannula that is sized to receive the body of the anchor, and a slot formed through a wall of the cannula at a distal end portion of the cannula and sized to receive the width of the spines; wherein when readied for use, the anchor is secured in the introducer with the body of the anchor inserted into the opening of the cannula with the pointed leading end of the body located proximal of the pointed distal end of the cannula, and with the spines of the anchor inserted into the slot of the cannula such that the anchor does not rotate relative to the cannula, wherein each of the plurality of spines is shaped as a shark fin with a curved leading edge meeting with a curved trailing edge at a point, with the curved leading edge diverging away from the pointed leading end of the body, and wherein the eyelet projects radially away from a center longitudinal axis of the body to extend outside of the cannula through the slot and as such is also configured to engage with the tissue during implantation of the anchor and has a width substantially equal to the width of the spines. an anchor; and an introducer provided to deliver the anchor into tissue; wherein the anchor includes a body having a pointed leading end that is configured to pierce the tissue, a plurality of spines projecting radially away from the body having a width and a height configured to allow the spines to engage with the tissue, an eyelet attached to a trailing end of the body, and a length of suture attached to the eyelet; wherein the introducer includes a cannula, the cannula having a pointed distal end, an opening formed in the cannula that is sized to receive the body of the anchor, and a slot formed through a wall of the cannula at a distal end portion of the cannula and sized to receive the width of the spines; wherein when readied for use, the anchor is secured in the introducer with the body of the anchor inserted into the opening of the cannula with the pointed leading end of the body located proximal of the pointed distal end of the cannula, and with the spines of the anchor inserted into the slot of the cannula such that the anchor does not rotate relative to the cannula, wherein each of the plurality of spines is shaped as a shark fin with a curved leading edge meeting with a curved trailing edge at a point, with the curved leading edge diverging away from the pointed leading end of the body, and wherein the eyelet projects radially away from a center longitudinal axis of the body to extend outside of the cannula through the slot and as such is also configured to engage with the tissue during implantation of the anchor and has a width substantially equal to the width of the spines.
