ABSTRACT:
To provide access to the circulatory system, and to allow withdrawal and return of blood, of a living body, a T shaped implantable device includes a bar having outlet ends connected to the circulatory system, and a shaft having an end for forming an access well connectable to an external exchange system. The device can be connected, or disconnected, to the external exchange system by means of a rotary plug which is in the shape of a substantially cylindrical, circular disk whose outer diameter corresponds substantially to the inside diameter of the access well. The rotary plug operates in conjunction with a complementary component in the access well to ensure that the disk bears with pressure on the bottom of the access well, such that the closure of the well is leakproof.
