Abstract
A system for use in peritoneal dialysis consisting of a rigid tubular implantable device, a stabilizing tool and an access set. The implantable device includes a centrally positioned, outwardly projecting cannula spike whose side openings are normally closed by a resilient sleeve member. A stabilizing tool having a broad load distributing base is locked to an upper flange of the implanted device. An access set connected to a dialysis solution system includes a septum which is penetrable by the cannula spike. Penetration simultaneously depresses the resilient cannula sleeve exposing the side openings which allows fluid flow. The access set, stabilizing tool and implant device are locked together whenever fluid is able to flow between the peritoneal cavity and the dialysis solution system.
