the portions being connected together in order to define a closed enclosure. ## Claims ### Claim 1 An orthotopic artificial bladder endoprosthesis comprising two portions connected to each other; each portion comprising a respective resorbable cap made of a PGA fiber fabric and a respective frame associated with said resorbable cap, each frame being made of a PGA/PLA copolymer and comprising a plurality of curved arms arranged as a star and defining a dome-like profile, wherein each frame is a load-bearing structure for the PGA fiber fabric of each portion to respectively assume the dome-like profile and each frame has a rigidity for maintaining the PGA fiber fabric of each portion respectively in the dome-like profile; said two portions being connected together to define a closed enclosure. ### Claim 2 (depends on 1) The endoprosthesis according to claim 1, wherein said two portions are connected together by resorbable suture. ### Claim 3 (depends on 1) The endoprosthesis according to claim 1, wherein said resorbable caps are mutually connected at their edges. ### Claim 4 (depends on 1) The endoprosthesis according to claim 1, wherein the curved arms of a first portion are fixed to the curved arms of a second portion. ### Claim 5 (depends on 1) The endoprosthesis according to claim 1, wherein the curved arms of a first portion are separated from the curved arms of a second portion. ### Claim 6 (depends on 1) The endoprosthesis according to claim 1, wherein the PGA fiber fabric of said resorbable caps is warp knitted fabric. ### Claim 7 (depends on 1) The endoprosthesis according to claim 1, wherein the PGA/PLA copolymer consists of 30% PGA and 70% PLA. ### Claim 8 (depends on 1) The endoprosthesis according to claim 1, wherein a thickness of the PGA fiber fabric is between 0.1 mm and 2 mm. ### Claim 9 (depends on 1) The endoprosthesis according to claim 1, wherein the PGA fiber fabric is obtained with a thread having a density between 50 and 200 denier. ### Claim 10 (depends on 1) The endoprosthesis according to claim 1, wherein the PGA fiber fabric of said resorbable caps is textured fabric. ### Claim 11 (depends on 1) The endoprosthesis according to claim 1, wherein a thickness of the PGA fiber fabric is between 0.3 mm and 0.6 mm. ### Claim 12 (depends on 1) The endoprosthesis according to claim 1, wherein a thickness of the PGA fiber fabric is between 0.4 mm and 0.53 mm. ### Claim 13 (depends on 1) The endoprosthesis according to claim 1, wherein a thickness of the PGA fiber fabric is 0.45 mm. ### Claim 14 (depends on 11) The endoprosthesis according to claim 11, wherein a thickness of the plurality of curved arms of each frame is between 0.5 mm and 2 mm. ### Claim 15 (depends on 1) The endoprosthesis according to claim 1, wherein the PGA fiber fabric of each resorbable cap is flexible, wherein each frame has the rigidity to maintain the PGA fiber fabric in the dome-like profile even under weight of growth of a musculo-fibrous capsule about the orthotopic artificial bladder endoprosthesis, and wherein the frames are obtained by injection of the PGA/PLA copolymer whose domed shape is imparted by thermoforming. ### Claim 16 (depends on 1) The endoprosthesis according to claim 1, wherein each frame is the load-bearing structure for the PGA fiber fabric, each cap is obtained from PGA fiber fabric with substantially circular flat form prior to being associated with the respective said frame and each frame has a self-supporting said domed shape. ### Claim 17 (depends on 1) The endoprosthesis according to claim 1, wherein each of the curved arms of the first portion is aligned with a respective said curved arm of the second portion. ### Claim 18 (depends on 1) The endoprosthesis according to claim 1, wherein each frame associated with the resorbable cap comprises the plurality of curved arms arranged as a star to define the dome-like profile and arranged outside the resorbable cap. ### Claim 19 (depends on 1) The endoprosthesis according to claim 1, wherein each frame is sufficiently rigid to have a self-supporting dome-like profile.
