1. A pre-strung serially connected system of suture anchors for forming an implanted array with anchor to anchor tensioned and independently locked suture stitches, the system comprising:
a plurality of serially positioned toggle bodies, including a first and a last toggle body in an array having at least a first hole and a plurality of intermediate toggle bodies between the first and the last toggle bodies in the array having at least a first and a second hole through the toggle body of the plurality of intermediate toggle bodies extending from a first longitudinal surface to a second longitudinal surface of the toggle body of the plurality of intermediate toggle bodies, each hole of the at least first and second holes spaced along an elongate toggle body of the plurality of serially positioned toggle bodies;
a plurality of independent cinchable working suture loops equal in number to one less than the total number of the plurality of serially positioned toggle bodies in the array, each independent cinchable working suture loop individually connecting a previous toggle body of the plurality of serially positioned toggle bodies in the array to a subsequent toggle body of the plurality of serially positioned toggle bodies in the array, wherein each cinchable working suture loop extends through respective holes of the at least a first hole of the plurality of serially positioned toggle bodies in the previous and subsequent toggle bodies of the plurality of serially positioned toggle bodies to form a loop that can be tensioned by pulling a free tail of the loop adjacent a slip knot formed therein; and,
a separate locking loop for each cinchable working suture loop, wherein the separate locking loop encircles a portion of a length of the cinchable working suture loop extending adjacent the second longitudinal surface of the toggle body of the plurality of intermediate toggle bodies, each separate locking loop having a first position allowing the cinchable working suture loop to slide through the separate locking loop and a second position engaging the cinchable working suture loop and preventing sliding within the separate locking loop to lock the cinchable working suture loop around which it encircles at each toggle body of the plurality of serially positioned toggle bodies after tensioning.
 
7. A system of toggle-type suture anchors connected serially by a plurality of independently cinchable working suture loops, the system comprising:
a plurality of toggle bodies, each having an elongate body with a plurality of passages extending from a top surface to a bottom surface, each passage spaced along the elongate body;
a plurality of independently cinchable working suture loops numbering one less than the plurality of toggle bodies, each cinchable working suture loop serially connecting a toggle body of the plurality of toggle bodies to the next toggle body of the plurality of toggle bodies to form a chain, wherein upon implantation the cinchable working suture loop can be tightened to form a suture stitch extending between each serial pair of toggle bodies of the plurality of toggle bodies; and,
an independent locking loop for each cinchable working suture loop extending from a passage at the bottom surface of each toggle body of the plurality of toggle bodies, except a first toggle body of the plurality of toggle bodies in the array, each independent locking loop encircling a portion of a length of the cinchable working suture loop, each independent locking loop having a first open position allowing the cinchable working suture loop to slide through the independent locking loop and a second closed position engaging the cinchable working suture loop and preventing sliding of the cinchable working suture loop.
 
14. A toggle-type suture anchor system with a plurality of cinchable working suture loops joining toggle bodies in series, the system comprising:
at least six toggle bodies, each having an elongated body having a generally flat top and bottom surfaces and rounded side surfaces, the rounded side surfaces defining a maximum diameter of the elongated body, each elongated body having at least a first and a second bore extending from the top surface to the bottom surface, each bore located at spaced intervals along the elongate body;
at least five cinchable working suture loops, one cinchable working suture loop of the at least five cinchable working suture loops connecting each toggle body of the at least six toggle bodies to the next in a serial chain, wherein each cinchable working suture loop can be collapsed in size after toggle body implantation to form a tensioned suture stitch between each subsequent toggle body of the at least six toggle bodies; and, a locking suture for each of the at least five cinchable working suture loops, each locking suture having a collapsible loop formed therein, with the collapsible loop of each locking suture extending from a bore at the bottom surface and encircling a portion of a length of each of the at least five cinchable working suture loops extending adjacent each toggle body of the at least six toggle bodies to which it is associated, the collapsible loop of each locking suture closing in response to tension on a leg of the locking suture passing up through the bore at the bottom surface and out at the top surface.
