A fastener delivery system comprising: a fastener comprising a first arm having a proximal end and a distal end, and a second arm having a proximal end and a distal end with a bridge extending from the proximal end of the first arm to the proximal end of the second arm, a first fluke of the fastener having a proximal end abutting the distal end of the first arm, and a second fluke of the fastener having a proximal end abutting the distal end of the second arm, wherein each of the first fluke and the second fluke define a passageway (124A, 124B) having a height dimension and extending at least partially through each fluke (106A, 106B), with each passageway (124A, 124B) defining at least one surface; and a fastener delivery tool for delivering the fastener into tissue of a patient, the fastener delivery tool comprising: a shaft; a handle assembly connected to a proximal end of the shaft; one or more prongs (154, 156) connected to a distal end of the shaft; and a fastener push rod received at least partially within the shaft, wherein the fastener push rod is connected to the handle assembly, wherein the fastener push rod is moveable relative to the shaft, wherein the fastener push rod further comprises a pair of arms (134A, 134B) connected to a distal end of the fastener push rod, and said fastener delivery system being characterized in that the fastener push rod includes one or more detents (137A, 137B) disposed on the pair of arms (134A, 134B) and which have a generally circular shape and which have a diameter sized appropriately to the height dimension of the first passageway and the second passageway which is slightly larger than the height dimension of the first and second passageway such that each of said detents is configured to press against a surface defined within the passageway (124A, 124B) to frictionally secure the fastener to the fastener push rod. a fastener comprising a first arm having a proximal end and a distal end, and a second arm having a proximal end and a distal end with a bridge extending from the proximal end of the first arm to the proximal end of the second arm, a first fluke of the fastener having a proximal end abutting the distal end of the first arm, and a second fluke of the fastener having a proximal end abutting the distal end of the second arm, wherein each of the first fluke and the second fluke define a passageway (124A, 124B) having a height dimension and extending at least partially through each fluke (106A, 106B), with each passageway (124A, 124B) defining at least one surface; and a fastener delivery tool for delivering the fastener into tissue of a patient, the fastener delivery tool comprising: a shaft; a handle assembly connected to a proximal end of the shaft; one or more prongs (154, 156) connected to a distal end of the shaft; and a fastener push rod received at least partially within the shaft, wherein the fastener push rod is connected to the handle assembly, wherein the fastener push rod is moveable relative to the shaft, wherein the fastener push rod further comprises a pair of arms (134A, 134B) connected to a distal end of the fastener push rod, and said fastener delivery system being characterized in that the fastener push rod includes one or more detents (137A, 137B) disposed on the pair of arms (134A, 134B) and which have a generally circular shape and which have a diameter sized appropriately to the height dimension of the first passageway and the second passageway which is slightly larger than the height dimension of the first and second passageway such that each of said detents is configured to press against a surface defined within the passageway (124A, 124B) to frictionally secure the fastener to the fastener push rod. a shaft; a handle assembly connected to a proximal end of the shaft; one or more prongs (154, 156) connected to a distal end of the shaft; and a fastener push rod received at least partially within the shaft, wherein the fastener push rod is connected to the handle assembly, wherein the fastener push rod is moveable relative to the shaft, wherein the fastener push rod further comprises a pair of arms (134A, 134B) connected to a distal end of the fastener push rod, and said fastener delivery system being characterized in that the fastener push rod includes one or more detents (137A, 137B) disposed on the pair of arms (134A, 134B) and which have a generally circular shape and which have a diameter sized appropriately to the height dimension of the first passageway and the second passageway which is slightly larger than the height dimension of the first and second passageway such that each of said detents is configured to press against a surface defined within the passageway (124A, 124B) to frictionally secure the fastener to the fastener push rod.
