Problems solved by technology

However, attachment with sutures cannot always be used, for example, where the ureter and / or urethra are weakened and / or thinned due to congenital or pathological causes
Additionally, the use of sutures requires great skill and a great deal of time during the replacement process

Embodiment Construction

[0032] figure 1 a shows the precursor of the prosthesis in the form of a capsule 600 . The bladder 600 is collapsible such that the filling and emptying mechanism of the resulting prosthesis operates due to the pressure differential between the air inside the prosthesis and the air outside the prosthesis. The capacity of the prosthesis is between 500 and 900 cm 3 between.

[0033] The capsule 600 is made of soft silicone (silicone) multi-layer film 2 ( figure 2 ) with a thickness of approximately 600 microns, thereby being compressible, sagable or collapsible as previously mentioned. Preferably, the membrane of bladder 600 is made of 20 layers of silicone, each layer having a thickness of approximately 30 microns. Preferably, said membrane 2 is manufactured by the method described in patent application WO2007 / 039159, which is incorporated herein by reference.

[0034] More particularly, multilayer film 2 is obtained from silicone as raw material by a manufacturing proces...

Abstract

A description is given of an orthotopic prosthesis (1) of artificial bladder comprising a balloon (600), two hollow elements (300) for the forced fitting of ureters (6,6') and a frustoconical element (602) for the connection of the urethra (8) to said prosthesis in the absence of stitches.

Description

technical field [0001] The present invention relates to an improved in situ artificial bladder prosthesis provided with elements for connection to the ureter and urethra. Background technique [0002] As is known, when a patient's bladder is affected by a severe, incurable pathological condition which jeopardizes the normal functioning of the bladder, it needs to be replaced with an artificial bladder prosthesis. [0003] Various schemes have been proposed to solve this problem, including replacing the autogenous bladder with a compressible bladder made of soft multi-layered silicone, whose urination occurs through simple compression of the lower abdomen, as described in the patent application described in WO 2007 / 039159. [0004] This type of prosthesis provides a connection between the artificial bladder and the ureters and urethra through the use of sutures. However, attachment with sutures cannot always be employed, for example, where the ureter and / or urethra are weak...
