Bladder reconstruction
First Claim
1. A method for the replacement or repair of a bladder, or portion of a bladder, in a human patient in need of such treatment comprising the steps of:
- a. providing a biocompatible synthetic, or natural, polymeric matrix structure in the shape of a bladder, or portion of a bladder, wherein said polymeric matrix is coated with a biocompatible and biodegradable shape-setting material comprising a liquefied poly-lactide-co-glycolide copolymer;
b. depositing at least one first cell population on or in said polymeric matrix; and
c. implanting the shaped polymeric matrix of step (b) into the human patient at a site of a bladder for the formation of a laminarily organized functional bladder structure.

Abstract
The invention is directed to methods and devices for the reconstruction, repair, augmentation or replacement of laminarily organized organs or tissue structures in a patient in need of such treatment. The device comprises a biocompatible synthetic or natural polymeric matrix shaped to conform to at least a part of the luminal organ or tissue structure with a first cell population on or in a first area and a second cell population such as a smooth muscle cell population in a second area of the polymeric matrix. The method involves grafting the device to an area in a patient in need of treatment. The polymeric matrix comprise a biocompatible and biodegradable material.

20. A device for the replacement or repair of a bladder, or portion of a bladder, in a human comprising:
- an implantable, biocompatible, synthetic or natural, polymeric matrix structure in the shape of a bladder or portion of a bladder having at least two separate surfaces, wherein the polymeric matrix is coated with a biodegradable shape-setting material comprising a liquefied poly-lactide-co-glycolide copolymer, and at least one first cell population deposited on or in said polymeric matrix to form an organized matrix/cell construct, wherein upon implantation of said organized matrix/cell construct into a human, said device forms a laminarily organized functional bladder structure.
