Abstract
A device to provide access to the circulatory system of a living body includes at least one tubular conduit and a housing integrally associated with the conduit and having fluid communication therewith through an aperture in the conduit wall at the point where the wall intersects the housing. Inside the housing is a rotatable valve adapted to receive a catheter to extend the fluid communication outside the living body. The valve is rotatable in the housing to selectively establish fluid communication between the circulatory system and the outside of the living body by means of a cannula receptacle provided in engaging relation with the valve. The cannula receptacle is adapted to engagingly receive the catheter. Structural restrictions, however, allow insertion and withdrawal of the catheter only when the valve is closed. Rotation of the valve occurs through the rotation of the catheter when the catheter is engagingly inserted in the cannular receptacle. A cap having a central aperture and a circumferential slot on its inner wall is provided to cover the open end of the assembly and to assure continuous seating of the valve. A tab is provided on the catheter tip to engage the circumferential slot and interlock the system when the valve is open.
