Embodiment Construction

[0021] Referring to the accompanying drawings, 1 as a whole represents the artificial bladder endoprosthesis in situ.

[0022] The endoprosthesis 1 comprises a first part 2 connectable to the patient's urethra and a second part 3 connectable to the patient's ureter.

[0023] The first part 2 and the second part 3 are distinct and differentiated, but are firmly connected together to define an enclosure within which is an enclosure for containing urine. The enclosure has a roughly between 100cm 3 with 900cm 3 The volume between, preferably 400cm 3 volume of.

[0024] In particular, the first part 2 is a part of the permanent type, while the second part 3 is a part of the resorbable type.

[0025] More particularly, the first part 2 includes a cover 4 made of a multilayer silicone film.

[0026] The thickness of the membrane of the cover 4 is between 500 μm and 700 μm, preferably about 600 μm.

[0027] In a preferred embodiment, the film comprises approximately 20 layers, e...

Abstract

An orthotopic artificial bladder endoprosthesis includes a first portion connectable to a urethra of a patient and a second portion connected to the ureters of the patient; the first portion including a collapsible cover made of a multi-layered silicone membrane having an external surface and an internal surface both coated with pyrolytic turbostratic carbon; the second portion including a resorbable cap including a fabric of PGA fibres and a frame, coupled with the cap, made using PGA / PLA copolymer; the cover and the cap being connected together along their respective edges, to define an enclosure.

Description

technical field [0001] The invention relates to an in situ artificial bladder prosthesis. Background technique [0002] The application of the present invention is in the replacement of a patient's bladder in the event that the patient's bladder suffers from a serious, incurable disease that jeopardizes the proper functioning of the bladder. [0003] Known intravesical prostheses comprise a balloon shell made of a layered silicone membrane. [0004] The balloon is sufficiently rigid to hold its shape securely and flexible enough to be manually compressed to ensure its emptying. [0005] The housing has a connection element in the lower part of the housing for connection with the patient's urethra. Similarly, two connectors are positioned at the top to enable connection with the ureter. [0006] These connections are made by stitching or by simple interlocking. [0007] Unfortunately, known endoprostheses have several disadvantages. [0008] Firstly, the connection of th...
