creating a vaginal incision,
transvaginally placing the tissue support portion in contact with the posterior vaginal tissue,
inserting a first needle with attached end of first extension portion through the vaginal incision,
transvaginally manipulating the first needle to lead the distal end of the first extension portion through the first tissue path in the region of the arcus tendineus,
inserting a second needle with attached end of second extension portion through the vaginal incision, and
transvaginally manipulating the second needle to lead the distal end of the second extension portion through a second tissue path in a region of an arcus tendineus.
6. The method of claim 1 comprising
providing an implant assembly comprising the implant comprising the tissue support portion, the first extension portion and a second extension portion, and a curved dilator attached to a distal end of each extension portion,
providing a surgical tool comprising a handle, a shaft, and a curved distal end, the curved distal end capable of engaging a first of the curved dilators,
creating a vaginal incision,
transvaginally placing the tissue support portion in contact with the posterior vaginal tissue,
engaging the curved distal end with the first curved dilator and inserting the first curved dilator with attached end of first extension portion through the vaginal incision,
transvaginally manipulating the first curved dilator to lead the distal end of the first extension portion through the tissue path on a first side of a patient,
engaging the curved distal end with a second of the curved dilators and inserting the second curved dilator with attached end of second extension portion through the vaginal incision,
transvaginally manipulating the second curved dilator to lead the distal end of the second extension portion through a second tissue path on an opposite side of the patient in a region of an arcus tendineus comprising a region from 2 centimeters above the arcus tendineus to the arcus tendineus and between an ischial spine and a distance 3 centimeters anterior to the ischial spine, wherein the second tissue path passes above an arcus tendineus through an obturator internus muscle, and wraps around the arcus tendineus, and wherein the tissue path does not extend to an external incision.
7. The method of claim 1 wherein the implant comprises
the tissue support portion,
a second elongate extension portion extending from the tissue support portion, and
two dilators, one each attached at an end of the two elongate extension portions.
8. The method of claim 7 wherein the dilators are curved dilators.
9. The method or claim 8 comprising providing an insertion tool comprising
a handle having a longitudinal axis,
a shaft having a proximal end and a distal end, the proximal end of the shaft attached at the distal end of the handle, the shaft having a longitudinal axis aligned with the longitudinal axis of the handle, and
the distal end being adapted to engage at least one of the dilators.
10. The method of claim 8 comprising engaging the insertion tool distal end with one of the two dilators and pushing the dilator along the tissue path.
11. A method of supporting posterior vaginal tissue, the method comprising
providing an implant comprising a tissue support portion and an extension portion extending from the tissue support portion,
contacting the support portion with posterior vaginal tissue,
producing a tissue path that passes between a position of the tissue support portion and a region of an arcus tendineus, wherein the region of the arcus tendineus comprises a region from 2 centimeters above the arcus tendineus to the arcus tendineus and between an ischial spine and a distance 3 centimeters anterior to the ischial spine, and through an obturator internus muscle, wraps around the arcus tendineus, and passes through a levator ani muscle back into a pelvic region, wherein the tissue path does not extend to an external incision, and
extending the extension portion through the tissue path.
12. A method of supporting posterior vaginal tissue, the method comprising
providing an implant comprising a tissue support portion and an extension portion extending from the tissue support portion,
contacting the support portion with posterior vaginal tissue,
producing a tissue path between a position of the tissue support portion and a region of an arcus tendineus, wherein the region of the arcus tendineus comprises a region from 2 centimeters above the arcus tendineus to 2 centimeters below the arcus tendineus and between an ischial spine and a distance 3 centimeters anterior to the ischial spine, and
extending the extension portion through the tissue path,
wherein the tissue path passes above the arcus tendineus to exit a pelvic region through an obturator internus muscle, wraps around the arcus tendineus, and passes through a levator ani muscle back into the pelvic region.
13. A method of supporting posterior vaginal tissue, the method comprising
providing an implant comprising a tissue support portion and an extension portion extending from the tissue support portion,
