Pelvic implant and therapeutic agent system and method

1. A pelvic implant configured for placement at a pelvic location and release of a therapeutic agent, the pelvic implant comprising:

at least one arm member; and

a central support portion coupled to the at least one arm member,

the central support portion including a multilayered film including a first outer therapeutic agent-containing layer, a second outer therapeutic agent-containing layer, an internal therapeutic agent-containing layer, a first regulating layer disposed between the first outer therapeutic agent-containing layer and the internal therapeutic agent-containing layer, and a second regulating layer disposed between the second outer therapeutic agent-containing layer and the internal therapeutic agent-containing layer, the first outer therapeutic layer having a rate of degradation that is faster than a rate of degradation of either of the first regulating layer and the second regulating layer,

the internal therapeutic agent-containing layer including an absorbable polymeric material and islands of hydrophilic polymer configured to adhere to the first regulating layer and the second regulating layer.

2. The pelvic implant of claim 1 , wherein the first regulating layer and the second regulating layer are configured to slow an elution of the therapeutic agent from the internal therapeutic agent-containing layer.

3. The pelvic implant of claim 1 , wherein the internal therapeutic agent-containing layer has a rate of degradation slower than the rate of degradation of the first regulating layer and the second regulating layer.

4. The pelvic implant of claim 1 , wherein the first and second outer therapeutic agent-containing layers comprise an aliphatic polyester copolymer or a polyorthoester.

5. The pelvic implant of claim 1 , wherein the internal therapeutic agent-containing layer and the first and second regulating layers comprise an aliphatic polyester homopolymer.

6. The pelvic implant of claim 1 , wherein the first and second outer therapeutic agent-containing layers are absorbable, the internal therapeutic agent-containing layer is partially absorbable, and the first and second regulating layers are non-absorbable, or partially absorbable.

7. The pelvic implant of claim 1 , wherein the first and second regulating layers comprise a polymeric material selected from the group consisting of crosslinked poly(vinyl pyrrolidone), poly((meth)acrylamide), poly(urethane), hyaluronic acid, alginate, dextran, starch, amylopectin, cellulose, xanthan, pullulan, chitosan, pectin, inulin, and heparin.

8. The pelvic implant of claim 1 , wherein the first and second regulating layers comprise pores having a size of 3 μm or greater.

9. The pelvic implant of claim 1 , further comprising:

a peripheral portion surrounding the central support portion, the at least one arm member extending from the peripheral portion,

wherein the peripheral portion is coupled to the multilayered film by a coupling member.

10. The pelvic implant of claim 9 , wherein the coupling member includes an adhesive or mechanical fastener.

11. The pelvic implant of claim 1 , wherein the central support portion includes a mesh, and the multi-layered film includes a first strip and a second strip, wherein the first strip and the second strip are woven through the mesh of the central support portion.

12. A pelvic implant configured for placement at a pelvic location and release of a therapeutic agent, the pelvic implant comprising:

a woven or non-woven mesh comprising a plurality of apertures along the pelvic implant in a first direction and a plurality of apertures along the pelvic implant in a second direction, the second direction being perpendicular to the first direction,

wherein a portion of the plurality of apertures are filled with membranes,

wherein the plurality of apertures along the implant in the first direction comprises a first membrane-filled aperture and a second membrane-filled aperture, the first membrane-filled aperture being separated from the second membrane-filled aperture by only one open aperture,

wherein the plurality of apertures along the pelvic implant in the second direction comprises a third membrane-filled aperture and a fourth membrane-filled aperture, the third membrane-filled aperture and the fourth membrane-filled aperture being separated by only one open aperture.

13. The pelvic implant of claim 12 wherein sizes of the apertures in the mesh are in a range of about 0.2 mm 2 to about 2 mm 2 .

14. The pelvic implant of claim 12 wherein one or more of the membrane-filled apertures include a photosensitive compound.

15. The pelvic implant of claim 12 wherein the membrane-filled apertures are in a range of about 10% to about 60% of a total amount of apertures in the pelvic implant.
