Tissue anchor system

A method of suburethral bladder neck suspension comprising the steps of:

• a. making an incision in a patient's body to access the urethra of said patient;
• b. inserting an anchor delivery device into said incision, said anchor delivery device comprising a hand-grip and an anchor stay adapted to reversibly mate with a tissue anchor;
• c. setting a first tissue anchor positioned on said anchor delivery device into soft tissue to resist removal, said first tissue anchor located near a first side of the bladder neck, said first tissue anchor comprising (i) an anchor body having a length and barbs extending outwardly from said anchor body, said anchor body having an opening sized to accommodate an anchor shaft, (ii) an anchor shaft moveable in said anchor body opening (iii) a series of interleaving members positioned on the anchor shaft or the interior of the anchor body opening;
• (iv) said first tissue anchor being adapted to engage said anchor stay where said anchor body is directly attached to said first tissue;
• wherein said first tissue anchor is set in said first tissue to resist removal by positioning said barbs of said set anchor body into said first tissue;
• d. attaching a sling having a first end to said first tissue anchor;
• e. positioning said sling under the bladder neck;
• and
• f. setting a second tissue anchor connected to a second end of said sling into tissue located near a second side of the bladder neck;
• said second tissue anchor resisting removal from said second tissue;
• g. after said first and second tissue anchors are set to resist removal, automatically adjusting the tension in said sling:
• (i) to increase tension by moving said anchor shaft further into said anchor body, and (ii) to decrease tension by moving said anchor shaft further out of said anchor body.
