Problems solved by technology

However, suturing with sutures is not always possible, for example in cases where the ureter and / or urethra are weakened and / or thinned due to congenital or pathological causes
Additionally, the use of sutures requires great manual skill and more time during the replacement procedure

Embodiment Construction

[0022] exist figure 1 A bladder prosthesis in the form of a closure or bag or collapsible balloon is shown in , which is generally designated with the reference number 1 . That is, the mechanism for filling and emptying of the prosthesis 1 works by the effect of the pressure difference between the air inside the prosthesis and the internal liquid (urine) inside the prosthesis 1 . The capacity of the prosthesis 1 is from 100 to 900 cm 3 between.

[0023] figure 1 The prosthesis 1 consists of a multilayer membrane 2 ( figure 2 ) composition (the multilayer film is made of flexible silicone) having a thickness such that it is compressible, collapsible or collapsible. The membrane of the prosthesis preferably has a thickness of about 600 microns and consists of 20 layers of silicone each having a thickness of about 30 microns. The silicone used may consist, for example, of a copolymer of dimethylsiloxane and m-vinylsiloxane reinforced with silicon. Preferably medical grade ...

Abstract

An orthotopic artificial bladder prosthesis includes an enclosure or bag or balloon and hollow elements (200; 300) for the forced connection of ureters and urethra to the bladder in the absence of sutures.

Description

technical field [0001] The present invention relates to an orthotopic artificial bladder prosthesis. Background technique [0002] It is well known that replacement of the bladder with an artificial bladder prosthesis is desirable when a patient's bladder is affected by a serious incurable disease that impairs its normal function. [0003] Among the various solutions developed to solve this problem, one is the replacement of the natural bladder with a compressible bladder made of flexible multilayer silicone as described in patent WO2007 / 039159, by simply squeezing Lower the abdomen to empty the compressible bladder. This type of prosthesis provides a connection between the ureter and urethra and the artificial bladder by using sutures. However, suturing with sutures is not always possible, for example in cases where the ureter and / or urethra are weakened and / or thinned for congenital or pathological reasons. Furthermore, the use of sutures requires great manual skill and...
