Abstract
An orthotopic artificial bladder endoprosthesis includes a casing made of a PGA fiber fabric; the casing having two first connectors for the connection with the ureters of a patient and a further connector for the connection with the urethra of a patient; an inflatable element inserted in the casing; the inflatable element being switchable between an inflated configuration, in which it supports and maintains in position the casing, and a deflated configuration.
Claims19
An orthotopic artificial bladder endoprosthesis for insertion into a patient configured to enable formation of a neobladder comprising:
- a casing made of a PGA fiber fabric configured to resorb over approximately one month;
- the casing having two first connectors for connection with the ureters of the patient and a second connector for connection with the urethra of the patient;
- and
- an inflatable element inserted in the casing and being independent of the casing;
- the inflatable element being switchable between an inflated configuration, in which the inflatable element is configured to support and maintain in position the casing the entire time necessary for the formation of a neobladder occurring at the same time as the progressive dissolution of the PGA casing in one month, and a deflated configuration,
- wherein the inflatable element comprises a membrane having an external surface, wherein the membrane of the inflatable element has an internal surface directed towards and defining an enclosure,
- wherein the inflatable element has a valve for introducing and extracting a fill fluid for expanding the inflatable element to the inflated configuration in which the inflatable element supports and maintains in position the casing,
- wherein the valve directly protrudes from the inflatable element,
- wherein the inflatable element defines the enclosure for the fill fluid, the valve being in direct communication with the enclosure,
- the valve adapted and configured to be within the casing when the inflatable element is in the inflated configuration,
- wherein in the inflated configuration the inflatable element extends across the casing to support opposed sides of the casing, wherein in the inflated configuration the inflatable element has a volume between 300 cm3 and 400 cm3 and the casing has a volume between 300 cm3 and 400 cm3.
