Abstract

The invention provides methods and devices for modulating the size of an implantable sling.

Claims

1. A device for cutting through an implantable sling, comprising

a handle,

a heating element in interoperative interconnection with the handle, and

a sling guide housing for guiding a portion of the implantable sling into contact with the heating element to cut through the portion of the implantable sling.

2. The device of claim 1, wherein the device includes a battery compartment.

3. The device of claim 1, wherein the device includes a switch for modulating power to the heating element.

4. The device of claim 1, wherein the device includes a temperature control element for modulating the temperature of the heating element.

5. The device of claim 1, wherein the device includes a power supply for operable interconnection with an external power source.

6. The device of claim 1, wherein the handle and the sling guide housing are aligned along the same axis.

7. The device of claim 1, wherein the handle and sling guide housing are aligned along different axes.

8. The device of claim 1, wherein the sling guide housing can be extended and retracted axially.

9. The device of claim 1, wherein the sling guide housing includes one or more slots axially oriented and extending radially through the sling guide housing.

10. The device of claim 1, wherein the sling guide housing includes two axially oriented diametrically opposed slots.

11. The device of claim 10, wherein the diametrically opposed slots are aligned with an apex of a section of the heating element.

12. The device of claim 10, wherein a width of the first slot and a width of the second slot are approximately equal.

13. The device of claim 10, wherein a width of the first slot is greater than a width of the second slot.

14. The device of claim 1, wherein the heating element comprises at least three sections and at least one section is sized and shaped to cut through the implantable sling.

15. The device of claim 14, wherein at least one section of the heating element has a length greater than or equal to the width of the implantable sling.

16. The device of claim 1, wherein the heating element comprises a nickel chromium wire.

33. A method for cutting through an implantable sling, comprising guiding a portion of the implantable sling into contact with the heating element of the device of claim 1, thereby cutting through the portion of the implantable sling.

17. A device for fusing an implantable sling, comprising

a handle,

a heating element in interoperative interconnection with the handle, and

a sling guide housing for guiding a portion of the implantable sling into contact with the heating element to fuse the portion of the implantable sling.

18. The device of claim 17, wherein the device includes a battery compartment.

19. The device of claim 17, wherein the handle and the sling guide housing are aligned along the same axis.

20. The device of claim 17, wherein the sling guide housing can be extended and retracted axially.

21. The device of claim 17, wherein the sling guide housing includes one or more slots axially oriented and extending radially through the sling guide housing.

22. The device of claim 17, wherein the sling guide housing includes two axially oriented diametrically opposed slots.

23. The device of claim 17, wherein the heating element comprises at least three sections and at least one section is sized and shaped to cut the implantable sling.

34. A method for fusing an implantable sling, comprising guiding a portion of the implantable sling into contact with the heating element of the device of claim 17, thereby fusing the portion of the implantable sling.

24. A device for fusing a first separate and independent implantable sling section with a second separate and independent implantable sling section, comprising

a handle,

a heating element in interoperative interconnection with the handle, and

a sling guide housing for guiding the first separate and independent implantable sling section and the second separate and independent implantable sling section into contact with the heating element, thereby fusing the first sling section with the second sling section.

25. The device of claim 24, wherein the housing includes a radially oriented extending notch near a distal end of the housing.

26. The device of claim 24, wherein a notch between a distal portion of the housing and a proximate portion of the housing forms a space between the heating element and an inner surface of the distal portion of the housing.

27. The device of claim 26, wherein the distal portion of the housing is a spacer sized and shaped to calibrate the length of the implantable sling.

28. The device of claim 24, wherein the housing can be extended and retracted axially to modulate a distance between the heating element and a distal-most end of the housing.

29. The device of claim 26, wherein the housing can be extended and retracted axially to modulate the distance between the heating element and the inner surface of the distal portion of the housing.

30. The device of claim 24, wherein the device includes a battery compartment.

31. The device of claim 24, wherein the handle and the housing are aligned along the same axis.

32. The device of claim 24, wherein the handle and housing are aligned along different axes.

35. A method for fusing a first separate and independent implantable sling section with a second separate and independent implantable sling section, comprising guiding the first separate and independent implantable sling section and the second separate and independent implantable sling section into contact with the heating element of claim 24, thereby fusing the first separate and independent implantable sling section with the second separate and independent implantable sling section.

36. A method for fusing a first separate and independent implantable sling section with a second separate and independent implantable sling section, comprising

contacting a first separate and independent implantable sling section and a second separate and independent implantable sling section with a heating element, and

supplying power to the heating element to fuse the first separate and independent implantable sling section with the second separate and independent implantable sling section.

37. A device for cutting through an implantable sling, comprising

a first elongated element and a second elongated element extending along first and second axes to intersect and cross at a pivot,

a heating element in operable interconnection with an inner surface of a distal portion of the first elongated element, and

a power supply in operable interconnection with the heating element.

38. The device of claim 37, wherein a proximal portion of the first elongated element includes the power supply.
