Abstract

A Y-connector including a hemostatic valve for enabling the introduction of an elongated member, e.g., a balloon catheter, into the body of a living being while precluding blood from flowing out of the valve. The Y-connector includes a housing having an interior in which a pair of resilient valve elements and a plunger mechanism are located. One valve element, e.g., a disk-like member, has a small diameter opening therein. The other valve element, e.g., a duck-bill valve elements, includes a normally closed, but openable, aperture therein. The plunger mechanism includes a tubular member having an outer diameter which is smaller than the diameter of the opening in the one valve element. The tubular member is arranged to be moved into and out of the opening in the one valve member and into and out of the aperture in the other valve element. The tubular member has a central passageway arranged to enable the elongated member to be readily extended therethrough for location at a desired position within the body of the being. The one valve element is arranged for engaging the periphery of the elongated member after the elongated member has been extended through the passageway and after the tubular member is moved out of the opening in the valve member to preclude blood from flowing through the interface between the valve member and the elongated member.
