an end of the first flexible strip is secured to the first end of the tissue support portion piece,
the first flexible strip loop extends from the first end of the tissue support portion piece and passes through the aperture at the proximal end of the first extension portion piece, from where the first flexible strip loop then extends to and passes through the aperture at the first end of the tissue support portion piece,
the first flexible strip extends away from the aperture at the first end of the tissue support portion piece as a loose end that can be pulled to tighten the first flexible strip loop to reduce a distance between the first extension portion piece and the tissue support portion piece.
4. The implant as recited at claim 3 comprising supportive portions consisting of a central support portion and two extension portions.
5. The implant as recited at claim 2 , wherein
an end of the first flexible strip is secured to the proximal end of the first extension portion piece,
the first flexible strip loop extends from the proximal end of the first extension portion piece and passes through the aperture at the first end of the tissue support portion piece, from where the first flexible strip loop then extends to and passes through the aperture at the proximal end of the first extension portion piece,
the first flexible strip extends away from the aperture at the proximal end of the first extension portion piece as a loose end that can be pulled to tighten the first flexible strip loop to reduce a distance between the first extension portion piece and the tissue support portion piece.
6. The implant as recited at claim 5 comprising supportive portions consisting of a central support portion and two extension portions.
7. The implant as recited at claim 5 comprising frictional features located on one of the first or the opposed second surfaces of the first and the second flexible strips.
8. The implant as recited at claim 7 , wherein the frictional feature includes teeth, ridges, extensions, bumps, lumps, bulges, protrusion, detents, or springs.
9. The implant as recited at claim 1 , wherein the implant has a length to allow the self-fixating tips to be placed at tissue of opposing obturator foramen of a patient, with the tissue support portion supporting tissue of a urethra or anus.
10. The implant as recited at claim 1 , wherein the first flexible strip comprises frictional features extending from one of the first and opposed second surfaces.
11. The implant as recited at claim 10 , wherein frictional features are formed by making a cut in the first flexible strip, wherein the frictional features lie flat when the flexible strip lies flat, and the frictional features extend from the one of the first and opposed second surfaces of the flexible strip when the flexible strip bends.
12. The implant as recited at claim 11 , wherein, when the first flexible strip passes through one of the apertures by bending, the frictional features extend from the one of the first and opposed second surfaces of the first flexible strip and engage a surface of the aperture, preventing movement of the first flexible strip in a manner that would increase the size of the first flexible strip loop.
13. The implant as recited at claim 11 , wherein, with the first flexible strip under tension, the frictional feature prevents movement of the first flexible strip in a manner that would increase the size of the first flexible strip loop.
14. The implant as recited at claim 10 , wherein the frictional feature is selected from: teeth, ridges, extensions, bumps, lumps, bulges, protrusion, detents, or springs.
15. The implant as recited at claim 1 , wherein, with the implant placed within a patient with the self-fixating tips at tissue of opposing obturator foramen and the central support portion supporting tissue of a urethra or anus, a proximal end of the first flexible strip is capable of being accessed through a medial incision of the patient to actuate the first adjusting mechanism.
16. A method of treating a pelvic condition, the method comprising providing an implant as recited at claim 1 ,
placing the implant in a patient to support pelvic tissue,
actuating the first adjusting mechanism to reduce a size of the first flexible strip loop.
17. The method as recited at claim 16 comprising actuating the second adjusting mechanism to reduce a size of the second flexible strip loop.
18. The method as recited at claim 16 , wherein the pelvic condition is selected from the group consisting of: fecal incontinence and urinary incontinence.
19. The method as recited at claim 16 for treating urinary incontinence, the method comprising:
creating a medial incision in the patient,
placing the tissue support portion piece to contact tissue to support a urethra,
placing the distal end of the first extension portion piece in a tissue path extending toward a first obturator foramen of the patient, and
placing the distal end of the second extension portion piece in a tissue path extending toward a second obturator foramen of the patient.
