A system for treating pelvic organ prolapse includes a shell and an anchor. The shell is made of biodegradable material that is insertable into a vagina. The shell has a convex exterior apex that is sized to contact an interior apical portion of the vagina. The anchor has a proximal portion that is attachable to the apex of the shell and a distal portion that is provided with a tissue fixation device that is attachable to tissue exterior the vagina such that the anchor and the shell combine to support and elevate the interior apical portion of a vagina.

1. A system for treating pelvic organ prolapse, the system comprising: a shell made of biodegradable material that is insertable into an organ, the shell having a convex exterior portion that is sized to contact an interior wall of the organ, with the convex exterior portion of the shell strengthened by a reinforcement structure provided in a region of the convex exterior portion of the shell; andan anchor having a proximal portion that is attachable to the shell and a distal portion that is provided with a tissue fixation device, the tissue fixation device is attachable to tissue exterior the organ such that the anchor and the shell combine to support and elevate the interior wall of the organ;wherein the shell includes an attachment feature on the convex exterior portion that is configured to couple with the proximal portion of the anchor. 2. The system of claim 1, wherein the convex exterior portion is an apex of the shell, and the apex of the shell is sized to contact an interior apical wall of a vagina. 3. The system of claim 1, wherein the shell includes a base opposite the convex exterior portion and the shell has a wall thickness at the base that is less than a wall thickness of the convex exterior portion. 4. The system of claim 1, wherein the shell is a substantially hollow. 5. The system of claim 1, wherein the shell is a hemispherical cap having a concave interior surface on a side of the shell that is opposite of the convex exterior portion. 6. The system of claim 1, wherein the reinforcement structure is encapsulated within the shell. 7. The system of claim 1, wherein the reinforcement structure is biodegradable. 8. The system of claim 1, wherein the reinforcement structure is part of the attachment feature. 9. The system of claim 1, wherein the reinforcement structure is a pattern that is pressed into an exterior wall of the shell. 10. The system of claim 1, wherein the reinforcement structure is one of a net, a screen, and a mesh. 11. The system of claim 1, wherein the convex exterior portion of the shell is textured. 12. The system of claim 1, wherein the convex exterior portion of the shell is porous and so configured to allow tissue to grow into the shell. 13. The system of claim 1, wherein the shell is fabricated from collagen. 14. A system for treating vaginal prolapse by supporting the vagina from inside of the vagina, the system comprising: a shell made of biodegradable material that is insertable into the vagina, the shell having an exterior apex that is sized to contact an interior apical portion of the vagina;a reinforcement structure applied to a region of the exterior apex of the shell; andan anchor having a proximal portion that is attachable to the exterior apex of the shell and a distal portion that is provided with a tissue fixation device that is attachable to tissue exterior the vagina such that the anchor and the shell combine to support and elevate the interior apical portion of a vagina;wherein the shell includes an attachment feature on the exterior apex that is configured to couple with the proximal portion of the anchor. 15. The system of claim 14, wherein the exterior apex is convex. 16. The system of claim 14, wherein the reinforcement structure is encapsulated within the shell. 17. The system of claim 14, wherein the shell is fabricated from collagen.
