Abstract
A medical insertion device that reduces the drag force exerted on an elongated member such as a catheter that is inserted through the device, increases maneuverability of the elongated member throughout the procedure in which the device is used and provides hemostasis. The device comprises a sheath housing and shuttle housing; the shuttle housing moves relative to the sheath housing. An elastomeric valve that contains an openable radial slit is provided in the sheath housing and provides hemostasis until the shuttle housing is biased towards the sheath housing. When the shuttle housing is biased forward, a generally tubular shuttle tube in the shuttle housing opens the slit in the elastomeric valve. The device is constructed so that, within the shuttle housing, hemostasis is provided after the shuttle tube has biased the elastomeric valve open.
