ABSTRACT:
A device to provide access to the circulatory system of a living body for simultaneous withdrawal and return of blood to the system includes a tubular conduit and a housing integrally associated with the conduit and having fluid communication therewith through at least one aperture in the conduit wall located at the point where the conduit adjoins the housing. The relation between the housing and the conduit is such that the axes of both intersect at right angles. The housing extends the fluid communication to a point outside the living body. Inside the housing is a movable valve body which has a pair of ports alignable with the aperture. The valve body is movable in the housing between positions of alignment and nonalignment of the apertures and the port to selectively establish fluid communication between the circulatory system and the outside of the living body.
