Knotless micro suture anchor array for high density anatomical attachment of soft tissue to bone

A pre-strung serially connected system of suture anchors for forming an implanted array with serial anchor to anchor suture stitches, the system comprising:

• at least four elongated toggle bodies, each toggle body having at least a first and a second hole through the toggle body extending from a first longitudinal surface to a second longitudinal surface of the toggle body with the first and second holes located at a spaced interval along the elongate toggle body and a longitudinally extending channel formed in the second surface of the elongated toggle bodies wherein the longitudinal channel intersects and extends at least between the first hole and second hole on the second surface;
• a single continuous suture serially connecting the at least four toggle bodies, the single continuous suture passing into the first hole on the first longitudinal surface and out the first hole on the second longitudinal surface, then back up through the second hole on the second longitudinal surface and out the second hole on the first longitudinal surface before going to the next toggle body, wherein each toggle body has a length of the single continuous suture extending adjacent the second longitudinal surface of the toggle body between the first and second hole of each toggle body, wherein the single continuous suture is configured to slide through the first and second holes of each toggle body when a force is applied thereto;
• and
• a separate locking loop for each toggle body, wherein the separate locking loop encircles a portion of the length of the single continuous suture extending adjacent the second longitudinal surface of the toggle body between the first and second hole, each separate locking loop having a first position allowing the single continuous suture to slide through the separate locking loop and a second position engaging the single continuous suture and preventing sliding within the separate locking loop to lock the single continuous suture at each toggle body after tensioning.

A system of serially connected toggle-type suture anchor comprising:

• a plurality of toggle bodies, each having an elongate body with a proximal, a middle and a distal passage extending from a top surface to a bottom surface, each passage located at spaced intervals along the elongate body with the middle passage between the proximal and distal passages and a longitudinally extending channel formed in the bottom surface of the elongated body wherein the longitudinal channel extends from the proximal bore to the middle bore, and from the middle bore to the distal bore on the bottom surface;
• a single working suture serially connecting the plurality of toggle bodies, the single working suture passing into the proximal passage at the top surface and out at the bottom surface, then back up through the distal passage at the bottom surface out at the top surface of each elongate body and leaving a length of suture extending past the middle passage adjacent the bottom surface of each elongate body;
• and
• an independent locking loop for each toggle body extending from the middle passage at the bottom surface, each independent locking loop encircling a portion of the length of the single working suture of each toggle body extending past the middle passage adjacent the bottom surface, the independent locking loop having a first open position allowing the single working suture to slide through the independent locking loop and a second closed position engaging the single working suture and preventing sliding of the single working suture within the independent locking loop.

A serially connected toggle-type suture anchor 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 a proximal, a middle and a distal bore extending from the top surface to the bottom surface, each bore located at spaced intervals along the elongate body with the middle bore between the proximal and distal bore and a longitudinally extending channel formed in the bottom surface of the elongated body wherein the longitudinal channel intersects and extends at least between the opening of the proximal, middle and distal bores on the bottom surface;
• and,
• a single working suture passing through each of the at least six toggle bodies by running serially into the proximal bore at the top surface and out at the bottom surface, then back up through the distal bore from the bottom surface and out at the top surface of each toggle body sequentially while leaving a length of the single working suture extending past the middle bore at the bottom surface of each elongate body.
