Sling delivery system and method of use
View Patent ↗An apparatus and method of use are disclosed to treat urological disorders. The biocompatible device includes a handle, needle, dilator and sling assembly configured to be minimally invasive and provide sufficient support to the target site. In addition, the configuration of the sling assembly also allows the sling to be adjusted during and/or after implantation. The device and treatment procedure are highly effective and produce little to no side effects or complications. Further, operative risks, pain, infections and post operative stays are reduced, thereby improving patient quality of life.

5. The assembly of claim 4 wherein the end of the first sheath overlaps the end of the second sheath.
6. The assembly of claim 1 comprising a tension adjustment member extending along a length of at least one of the first elongate end section and the second elongate end section.
7. The assembly of claim 6 wherein the tension adjusting member comprises a suture extending along a length of the first elongate end section, a length of the middle portion, and a length of the second elongate end section.
8. The assembly of claim 1 wherein the first sheath covers the first elongate end section, the second sheath covers the second elongate end section, an end of the first sheath is located at the middle portion and an end of the second sheath is located at the middle portion.
9. The assembly of claim 8 wherein the end of the first sheath overlaps the end of the second sheath.
10. The assembly of claim 1 comprising the needle and a second needle, the second needle sized and shaped to extend substantially between an abdominal wall and vaginal tissue of a female patient.
11. The assembly of claim 10 comprising the connector and a second connector attached to the second elongate end section, the second sheath, or both, the second connector comprising a second connector proximal end and a second connector distal end, the second connector proximal end attached to the second elongate end section, the second sheath, or both, and the second connector distal end adapted to engage the distal end of the second needle in a manner that allows the second needle to pull the second connector through tissue.
12. The assembly of claim 11 wherein the first connector is a first dilating connector and the second connector is a second dilating connector.
13. The assembly of claim 12 wherein the first dilating connector includes a tapered surface and the second dilating connector includes a tapered surface.
14. The assembly of claim 12 wherein the first dilating connector includes a tapered surface and the second dilating connector includes a tapered surface.
15. A surgical device according to claim 11 wherein the first connector is shaped to deflect tissue out of the path of the first connector and the second connector is shaped to deflect tissue out of the path of the second connector.
16. A method of treating urinary incontinence in a female patient comprising the steps of:
creating at least one incision in vaginal tissue,
creating one or more suprapubic incision,
providing an assembly according to claim 1 ,
passing the needle between the at least one vaginal incision and the one or more suprapubic incision,
using the needle to pass the first elongate end section through tissue of the patient between the at least one vaginal incision and the one or more suprabubic incision to locate the implantable mesh in a therapeutically effective position relative to the urethra of the patient, and
removing the first sheath.
17. The method of claim 16 comprising passing the second elongate end section through tissue of the patient between the at least one vaginal incision and the one or more suprabubic incision and removing the second sheath.
18. The method of claim 16 wherein
passing the needle between the at least one vaginal incision and the one or more suprapubic incision comprises inserting a first end of the needle into the one or more suprapubic incision and passing the first end of the needle through tissue of the patient to the at least one vaginal incision; and
passing the second needle between the at least one vaginal incision and the one or more suprapubic incision comprises inserting a first end of the second needle into the one or more suprapubic incision and passing the first end of the second needle through tissue of the patient to the at least one vaginal incision.
19. The method of claim 18 wherein the assembly comprises:
the connector and a second connector attached to the second elongate end section, the second sheath, or both, and adapted to engage the second needle; and
the needle and a second needle, the second needle sized and shaped to extend substantially between an abdominal wall and vaginal tissue of a female patient.
20. The method of claim 19 comprising
with the needle located between the at least one vaginal incision and the one or more suprapubic incision, connecting the connector to the first end of the needle,
with the second needle located between the at least one vaginal incision and the one or more suprapubic incision, connecting the second connector to the first end of the second needle,
removing the needle from the patient by pulling the needle from the one or more suprapubic incision to pass the first elongate end section through tissue of the patient between the at least one vaginal incision and the one or more suprabubic incision; and
removing the second needle from the patient by pulling the second needle from the one or more suprapubic incision to pass the second elongate end section through tissue of the patient between the at least one vaginal incision and the one or more suprabubic incision.
21. A method of treating urinary incontinence in a female patient comprising the steps of:

creating one or more suprapubic incision,
providing an assembly according to claim 1 comprising the needle sized and shaped to extend substantially between an abdominal wall and vaginal tissue of a female patient, and a second needle sized and shaped to extend substantially between an abdominal wall and vaginal tissue of a female patient;
passing the needle between the at least one vaginal incision and the one or more suprapubic incision;
passing the second needle between the at least one vaginal incision and the one or more suprapubic incision;
using the needle to pass the first elongate end section through tissue of the patient between the at least one vaginal incision and the one or more suprabubic incision;
removing the first sheath;
using the second needle to pass the second elongate end section through tissue of the patient between the at least one vaginal incision and the one or more suprabubic incision to locate the implantable mesh in a therapeutically effective position relative to the urethra of the patient; and
removing the second sheath.
