Abstract

A valved connector for a device for penetrating the arterial system of a patient. The connector comprises a tubular housing having a bore, plus a first valve for controlling back leakage through the tubular housing bore. The first valve is adjustably openable and closable to permit an elongated member to pass through the lumen of the first valve and bore of the housing, with the first valve providing selectively controllable sealing about the elongated member. A second valve is carried, typically proximal of the first valve. The second valve comprises a slit, resilient partition permitting the elongated member to pass through the slit partition with added sealing. Thus, back leakage through the housing can be controlled by the second valve when the first valve is opened, so that the elongated member passing through the connector can be easily moved by releasing the first valve without significant back leakage, so that the elongated member may be easily moved through the connector, but may be strongly sealed at any desired time.
