Abstract
A device to provide access to the circulatory system of a living body includes a conduit and a housing integrally associated with the conduit and having fluid communication therewith through an aperture in a wall common to both. The housing extends the fluid communication to a point outside the living body. Inside the housing is a movable valve body which has a port alignable with the aperture. The valve body is movable in the housing between positions of alignment and non-alignment of the aperture and the port to selectively establish fluid communication between the circulatory system and the outside of the living body. At least the surfaces of all parts of the device that contact blood and tissue are made of biologically compatible material.
