Implant positioning system and method

A method of treating urinary incontinence comprising:

• a) having a system for accurate positioning and delivery of materials in vivo, the system comprising,
• (i) an injector having an expulsion end and an opposite end, the opposite end having a 5 syringe attached thereto, the injector containing a bulking implant for treating urinary incontinence;
• (ii) a viewing instrument having a distal end and a proximal end which remains outside the body;
• and,
• (iii) a housing, the housing including a through cavity adapted to hold the viewing instrument, the housing further including a plurality of injector through cavities, each injector through cavity being adapted to hold the injector at an angle to the viewing instrument, each injector through cavity resulting in a different angle between the injector and the viewing instrument;
• the expulsion end of the injector being positioned proximate to the distal end of 15 cystoscope;
• b) selecting an injector through cavity through which to insert the injector and inserting the injector therethrough;
• c) inserting the distal end of the viewing instrument into a urethra;
• d) making an incision in the periurethral tissue using the expulsion end of the injector;
• e) accurately positioning the expulsion end of the injector using the viewing instrument;
• f) applying pressure to the syringe such that the bulking implant is delivered into the incision in the periurethral tissue;
• g) removing the expulsion end of the injector and the distal end of the viewing instrument from the urethra.

A method of treating urinary incontinence comprising the steps of:

• a) creating a pocket in the periurethral tissue by a process comprising the steps of:
• (i) making an incision in the periurethral tissue;
• (ii) inserting a balloon catheter into the incision;
• (iii) filling the balloon catheter with a fluid or a gas;
• 10 (iv) removing the fluid or gas from the balloon catheter;
• and,
• (iv) removing the balloon catheter from the incision;
• b) inserting bulking material into the pocket.
