Abstract
The object of the invention is an implant not requiring major surgery for its insertion or for the partial replacement of any of its elements; said prosthesis can be applied for long-term placement. The implant disclosed replaces the entire urinary organs, thereby precluding any possible anastomosis, said implant comprising a double-layered (7, 8) structure for the artificial replacing elements: tubular elements (1, 3) for the renal ducts and urethra, a reservoir (2) for the bladder, and an artificial urethral sphincter (4). The aritificial tubular elements of renal ducts (1) are connected to the reservoir (2) by mechanical attachments (5), said elements (1 to 3) being constituted and formed so that they can pass from a flattened state when empty to an expanded state. The two layers (7, 8) join to form the tubular elements (1, 3), forming respectively an external shell which is sufficiently flexible to submit to deformation by manual pressure, and an internal pocket, which is supple and extractable from the shell, constituting the reservoir (2). This structure allows for the partial replacement of each of its elements and ensures the long-term placement of the prosthesis.
