A Y-adapter (2) includes a check valve (22) having an entrance section (24) and a sealing section (26). The sealing section includes two or more flexible, thin, conformable sheets (48, 50) having normally abutting sealing surfaces extending axially at least twice the diameter of the therapeutic catheter (6). The sealing section collapses onto the catheter so that the patient's blood pressure seals the sheets against the catheter to prevent blood loss even during insertion and removal of the catheter. The main bore (10) is sealed adjacent the side port (20) to eliminate dead space where blood clots can form. The flexible, conformable sheets provide very little resistance to the insertion of the catheter to minimize damage to the catheter.
