EXPANDER OF ORTHOTOPIC ARTIFICIAL BLADDER ENDOPROSTHESIS

摘要

A description is given of a deformable and expandable element, or expander, for internal support for an orthotopic artificial bladder endoprosthesis in a textile of biodegradable biocompatible material, characterised in that the expander has a substantially hollow shape, made in medical grade silicone elastomer, and provided with a conduit for injecting in its interior a fluid so as to change from a non-expanded configuration to an expanded configuration, the conduit being integral with a one-way check valve applied on the expander.
