the mechanical stop can be removed and the sheath can be placed in the uncovered configuration.
4. The combination according to claim 3 wherein the mechanical stop comprises a moveable extension that can be moved to engage or disengage the sheath by an actuator located on the handle.
5. The combination according to claim 4 wherein
the hollow tube sheath comprises an aperture in a sidewall at the proximal tube end,
in the covered configuration, the extension is located within the aperture and inhibits movement of the hollow tube sheath in a proximal direction and in a distal direction along the shaft,
the extension can be removed from the aperture to allow the hollow tube to be placed in the uncovered configuration.
6. The combination according to claim 3 wherein
the hollow tube sheath comprises a proximal tube end and a distal tube end,
the handle comprises a recess at a connection of the handle to the shaft proximal end, the recess being capable of accepting the proximal end of the hollow tube sheath,
the hollow tube sheath moves from the covered configuration to the uncovered configuration by the proximal tube end moving in a direction toward the recess.
7. The combination according to claim 1 wherein, in the uncovered configuration, a length of from 0.5 to 1.5 centimeters of the distal shaft end is uncovered.
8. The combination as recited in claim 1 , wherein
the sheath can be moved between the covered configuration and the uncovered configuration, and
in the uncovered configuration the sheath covers the proximal shaft end.
9. The combination as recited in claim 1 , wherein the implant comprises
a tissue support portion, and
a set of two superior extension portions extending from the tissue support portion, and a set of two inferior extension portions extending from the tissue support portion, wherein, when the tissue support portion is placed to support tissue of a vagina, each superior extension portion can be connected to tissue of an opposing obturator foramen, and each inferior extension portion can be connected to sacrospinous ligament.
10. The combination as recited in claim 1 , comprising one or more of a grommet management tool and an adjusting tool.
11. The combination as recited in claim 1 , wherein
the tool is adapted to engage the tissue fastener and to place the tissue fastener at a sacrospinous ligament,
the combination further comprising a second insertion tool adapted to place a second tissue fastener at an obturator foramen.
12. The combination of claim 1 wherein the extension portion piece comprises a mesh portion and a non-mesh portion.
13. The combination of claim 12 wherein the extension portion piece comprises a tissue fastener at an end of the mesh portion.
14. The combination of claim 12 wherein the support portion piece comprises an adjusting engagement for adjustably engaging the extension portion piece.
15. The combination of claim 14 wherein the support portion piece further comprises two additional tissue fasteners.
16. The combination of claim 1 wherein in the covered configuration the sheath is capable of covering at least a portion of the extension portion piece.
17. The combination of claim 1 wherein in the covered configuration, the sheath covers at least a portion of the extension portion piece.
18. The combination of claim 1 wherein the tissue fastener comprises
a base having a proximal base end and a distal base end;
an internal channel extending from the proximal base end at least partially along a length of the base toward the distal base end; and
a lateral extension extending from the base,
and wherein the distal shaft end is capable of engaging the tissue fastener in a manner to allow the insertion tool to push the tissue fastener.
19. The combination of claim 1 wherein the distal shaft end is capable of engaging the tissue fastener in a manner to allow the insertion tool to push the tissue fastener.
20. The combination of claim 1 wherein the extension portion piece comprises a mesh portion and non-mesh portion, the mesh portion comprising a distal end connected to the tissue fastener, and a proximal end connected to a distal end of the non-mesh portion.
21. The combination of claim 1 wherein in the covered configuration, and with the tissue fastener engaged with the distal shaft end, the extension portion piece can be placed within the sheath.
22. The combination of claim 1 wherein:
the tissue fastener comprises
a base having a proximal base end and a distal base end;
an internal channel extending from the proximal base end at least partially along a length of the base toward the distal base end; and
a lateral extension extending from the base;
wherein the distal shaft end is capable of engaging the tissue fastener in a manner to allow the insertion tool to push the tissue fastener;
wherein the extension portion piece comprises a mesh portion and non-mesh portion, the mesh portion comprising a distal end connected to the tissue fastener, and a proximal end connected to a distal end of the non-mesh portion; and
wherein in the covered configuration and with the tissue fastener engaged with the distal shaft end, at least a portion of the extension portion piece can be placed within the sheath.
23. A method of implanting an implant in a patient, the method comprising
providing a combination as recited in claim 1 ,
engaging the tissue fastener with the distal shaft end,
placing the sheath over the shaft and engaged tissue fastener with the sheath in a covered configuration that covers the distal shaft end and engaged tissue fastener,
inserting the shaft and engaged tissue fastener into a patient, with the sheath placed over the shaft in the covered configuration,
moving the sheath to an uncovered configuration that uncovers the tissue fastener, and
fastening the tissue fastener to tissue.
24. The method of claim 23 comprising inserting the tissue fastener into soft tissue selected from sacrospinous ligament and coccygeus muscle.
25. The method of claim 24 wherein the implant comprises
a tissue support portion, and
a set of two superior extension portions extending from the tissue support portion, and a set of two inferior extension portions extending from the tissue support portion,
the method comprising placing the tissue support portion to support tissue of a vagina,
fixing each superior extension portion to tissue of an opposing obturator foramen,
fixing each inferior extension portion to soft tissue of sacrospinous ligament or coccygeus muscle.
