ABSTRACT:
An artificial anus includes a hollow tubular support member, having a cylindrical body portion and a pair of radially-extending flanges at the two opposed open ends of the body portion, and a releasable plug for sealingly closing the hollow support member. The support member is suitable for implantation within an opening in the abdominal wall of the patient, with one of the radially-extending flanges lying upon the dermis or subcutaneous tissue, the other of the flanges lying on the fascia or peritoneum, and the end of the patient's colon received within the support member. Inner and outer layers of at least a portion of the cylindrical body portion are capable of receiving soft tissue ingrowth. A pressure transducer or electrical contact is provided on the support member and connected to an electrode in contact with the patient's skin, so that when the colon becomes pressurized the patient is signalled that the plug should be released. The device can be modified to serve as an artificial bladder or implantable body access device.
