ABSTRACT:
A vascular access sheath is provided for introducing catheters, stents, and other interventional devices into blood vessels. The invention comprises a stiff tubular catheter segment, which is designed to remain outside the body, having two hemostatic valves, most preferably of an iris valve design disposed at each end. A flexible sheath extends from one of the valves for insertion into the blood vessel. In operation, the valves are opened and closed one at a time, to allow relatively large devices to be introduced into the blood vessel without the valve pressing against the devices and with minimal loss of blood.
