Abstract

A device for the expansion of an atrophied bladder formed by a hemisphere (100,200), as a single piece, in biocompatible material, characterized in that the material is selected from polylactic acid (PLA) and silicone coated with pyrolytic turbostratic carbon or with amorphous diamond-like carbon.

Claims

1-8. -8. (canceled)

9. An implant for increasing the volume of an atrophied bladder, said implant being constituted by a domed hemisphere device, internally hollow with a predetermined volume, made in a single piece in biocompatible material, the internal and external surfaces of said hemisphere are without covering from semination of cultured cells, characterised in that said material is silicone coated with pyrolytic turbostratic carbon or with amorphous diamond-like carbon, and in that said hemisphere is suitable for acting as a scaffold and for growing thereon autologous cells from fibrous capsule, generated by the process of tissue reconstruction of the patient, after its insertion inside the patient.

10. The implant according to claim 9 wherein the diameter of the hemisphere is about 80 mm.

11. The implant according to claim 9 wherein the hemisphere has a rim turned upwards.

12. The implant according to claim 9 wherein the hemisphere has a thickness ranging from 0.1 mm to 2 cm.

13. The implant according to claim 12 wherein the hemisphere has on the rim a plurality of holes, with a diameter of the holes comprised between 0.1 and 3.0 mm.

14. The implant according to claim 9 wherein the coating of pyrolytic turbostratic carbon or amorphous diamond-like carbon is a microfilm of about 0.2-0.3 micron.

15. The implant according to claim 9 wherein the suture thereof to the bladder is performed by using suture threads made of absorbable or non-absorbable material.

16. The implant according to claim 10 wherein the hemisphere has a rim turned upwards.

17. The implant according to claim 9 wherein the hemisphere has a thickness ranging from about 0.5-0.6 mm.
