Abstract

In some embodiments, a method includes extending a dilator into a body of a patient in a first direction such that a distal end portion of the dilator extends from the body. The dilator defines a lumen therethrough. At least a portion of the dilator is disposed within the body when the distal end portion extends from the body. At least a portion of an implant is passed through the lumen defined by the dilator. The dilator is removed from the body by moving the dilator in the first direction.

Claims

1. A method, comprising:

extending a dilator into a body of a patient in a first direction such that a distal end portion of the dilator extends from the body, the dilator defining a lumen therethrough, at least a portion of the dilator being disposed within the body when the distal end portion extends from the body;

passing at least a portion of an implant through the lumen defined by the dilator; and

removing the dilator from the body by moving the dilator in the first direction.

2. The method of claim 1, wherein the extending includes pushing the distal end portion of the dilator through the body.

3. The method of claim 1, wherein the extending includes pulling the distal end portion of the dilator through the body.

4. The method of claim 1, wherein the extending includes extending the dilator into a portion of the body in a pelvic region of the patient.

5. The method of claim 1, wherein the extending includes aligning a proximal end of the dilator with a surface of the body such that the proximal end is flush with the surface.

6. The method of claim 1, wherein, during the extending, the distal end portion of the dilator is configured to contact a portion of a delivery needle.

7. The method of claim 1, wherein the extending includes extending the dilator into the body via a first skin incision, and the removing includes removing the dilator from the body via a second skin incision.

8. The method of claim 1, wherein the passing includes pushing the portion of the implant through the lumen in the first direction.

9. The method of claim 1, wherein the passing includes pulling the portion of the implant through the lumen in the first direction.

10. The method of claim 1, wherein the passing includes passing the portion of the implant through the lumen in a second direction opposite the first direction.

11. The method of claim 1, wherein the first direction is a distal direction.

12. The method of claim 1, wherein a proximal end portion of the dilator includes an enlarged portion in fluid communication with the lumen, the enlarged portion configured to facilitate the passing.

13. The method of claim 1, wherein the implant is configured to be used to treat male incontinence.

14. A method, comprising:

extending a dilator into a body of a patient such that a distal end portion of the dilator extends from the body, the distal end portion of the dilator being coupled to a first portion of a suture such that the first portion of the suture is disposed within the body when the distal end portion of the dilator extends from the body, the suture having a second portion coupled to an implant, the dilator defining a lumen therethrough,

uncoupling the first portion of the suture from the distal end portion of the dilator;

passing at least a portion of the implant through the lumen defined by the dilator by pulling on the first portion of the suture;

removing the dilator from the body through a skin incision.

15. The method of claim 14, further comprising:

coupling the first portion of the suture to the distal end portion of the dilator, the distal end portion of the dilator defining an aperture through which the first portion of the suture is disposed.

16. The method of claim 14, further comprising:

after the removing, trimming the portion of the implant extending through the bodily tissue such that the suture is detached from the implant.

17. The method of claim 14, wherein the extending includes extending the dilator into a portion of the body in a pelvic region of the patient.

18. The method of claim 14, wherein the extending includes extending the dilator into the body in a first direction, and the removing includes removing the dilator from the body in a direction substantially the same as the first direction.

19. The method of claim 14, wherein the extending includes extending the dilator into the body in a first direction, and the removing includes removing the dilator from the body in a second direction substantially opposite the first direction.

20. The method of claim 14, wherein the extending includes extending the dilator into the body and through a portion of an obturator.
