Surgical articles for placing an implant about a tubular tissue structure and methods
View Patent ↗A minimally invasive surgical instrument for placing an implantable article about a tubular tissue structure is disclosed. The surgical instrument is particularly useful for treating urological disorders such as incontinence. Surgical methods using the novel instrument are also described.
1. A method of treating a patient's incontinence comprising the steps of:
inserting a surgical device with an implantable article situated therein into a urethra, wherein the implantable article is comprised of an elongate tubular tissue structure:
moving the implantable article from a position within the urethra to a position a least substantially external to the urethra;
separating the implantable article from the device; and
removing the surgical device from the urethra leaving the implantable article situated about the urethra.
2. A method of treating incontinence according to claim 1 wherein the patient is female and the incontinence is treated without requiring an incision in the vagina or abdomen of the patient.
3. A method of treating female urinary incontinence comprising the steps of:
providing a surgical device having an immobilizer and a stabilizer, and a implantable article deployment member movable about the immobilizer between a retracted position and an extended position;
inserting the immobilizer into the urethra and the stabilizer within the vagina;
moving the implantable article deployment member about the immobilizer from the refracted to the extended position thereby facilitating rotation of the implantable article adapted to cause penetration of urethral tissue and movement of the implantable article along a path that is substantially external to the urethra;
retracting the implantable article deployment member from the extended to the retracted position leaving the implantable article situated about the urethra;
separating the implantable article from the device; and
removing the surgical device from the patient's body.
4. A method according to claim 3 wherein the implantable article treats the incontinence without substantially changing the patient's urinary tract orientation to avoid post implantation voiding difficulties.
