Method and device for anchor implantation and support of bodily structures
First Claim
1. A device for suspending, stabilizing, and/or slightly compressing a bodily structure, the device comprising:
- a delivery needle comprising an elongate cannula with a proximal end, a distal end, and a body portion;
a stylet comprising an elongate rod for being matingly received into the cannula of the delivery needle; and
a support comprising an anchor toggle and elongate first and second sutures wherein each of the first and second sutures has a first end secured to the anchor toggle and a free second end wherein each of the first and second sutures extend from a central portion of the anchor toggle;
whereby the delivery needle and the stylet can be used to deploy the anchor toggle remotely in a desired location in a body to provide support for the first and second sutures and thereby to support, stabilize, and/or compress a bodily structure.

Abstract
A method and device for suspending, stabilizing, and/or slightly compressing a bodily structure, such as a urethrovesical junction. The device comprising a delivery needle with a trocar, a stylet for being matingly received into the delivery needle, and a support formed by an anchor toggle and elongate first and second sutures. A longitudinal slot can be disposed at the distal end of the delivery needle for allowing the sutures to protrude therefrom. The delivery needle can have a curve with the slot and a base of the trocar disposed on an inside of the curve. An aligning handle, visual and tactile orientation indicators, and depth indicators can be disposed on the delivery needle for allowing a determination of the orientation, depth, and location of the distal end of the delivery needle. A sling can be used to spread a supporting force of the sutures over a greater area.

18. A device for suspending, stabilizing, and/or slightly compressing a bodily structure, the device comprising:
-
a delivery needle comprising an elongate cannula with a proximal end, a distal end, and a body portion;
a trocar disposed at the distal end of the delivery needle;
a stylet comprising an elongate rod for being matingly received into the cannula of the delivery needle; and
a support comprising an anchor toggle and elongate first and second sutures wherein each of the first and second sutures has a first end secured to the anchor toggle and a free second end wherein each of the first and second sutures extend from a central portion of the anchor toggle;
a longitudinal slot formed in the delivery needle wherein the longitudinal slot begins at the distal end of the cannula, communicates longitudinally along the cannula, and terminates a given distance away from the distal end of the cannula whereby the support can be retained within the distal end of the delivery needle with the anchor toggle at least partially disposed in the distal end of the delivery needle and the first and second sutures protruding from the slot;
wherein the body portion of the delivery needle has a curve therein, wherein the trocar is angled such that the trocar has a distal tip and a proximal base with the distal tip of the trocar disposed on an outside of the curve in the delivery needle, and wherein the slot is disposed in the base of the trocar and on an inside of the curve whereby the first and second sutures protrude through the slot on the inside of the curve;
whereby the delivery needle and the stylet can be used to deploy the anchor toggle remotely in a desired location in a body to provide support for the first and second sutures and thereby to support, stabilize, and/or compress a bodily structure. - View Dependent Claims (19, 20)

21. A method for the correction of urinary incontinence without percutaneous incision, the method comprising the steps of:
-
providing a delivery needle comprising an elongate cannula with a proximal end, a distal end, and a body portion;
providing a stylet comprising an elongate rod for being matingly received into the cannula of the delivery needle;
providing a urethrovesical support comprising an anchor toggle with at least an elongate first suture with a proximal end fixed to the anchor toggle and a free distal end;
inserting the distal end of the elongate cannula of the delivery needle partially into a perineum of a patient'"'"'s body that has a bladder structure with a bladder, a urethrovesical junction, and a urethra;
passing the distal end of the cannula through the perineum wall, across the space of the Retzius behind the symphysis pubis, and then to a desired supporting location but not so far that the distal end of the cannula or the anchor toggle creates a percutaneous incision;
inserting the anchor toggle of the urethrovesical support at least partially into the cannula of the delivery needle;
inserting the elongate rod of the stylet into the proximal end of the cannula of the delivery needle;
deploying the anchor toggle of the urethrovesical support by sliding the elongate rod of the stylet increasingly deeper into the cannula of the delivery needle at least until the distal end of the elongate rod drives the anchor toggle out of the distal end of the cannula and into the desired supporting location;
removing the elongate cannula of the delivery needle from the patient'"'"'s body thereby leaving the anchor toggle in position and leaving the at least one elongate first suture in place; and
coupling the at least one suture to the bladder structure of the patient'"'"'s body thereby providing support, compression, and/or stabilization to the bladder structure with the anchor toggle acting as a supporting anchor and the at least one suture acting as a supporting line;
whereby urinary stress incontinence in the patient can be corrected. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
