MEDICAL INSERTION DEVICE WITH HEMOSTATIC VALVE

摘要

A medical insertion device that reduces the drag force exerted on an elongat ed member such as a catheter 43b 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 20 and shuttle housing 22 wherein the shuttle housing moves relative to the sheath housing. An elastomeric valve 2 8 that contains an openable radial slit 60 is provided in the sheath housing and provides he mostasis until the shuttle housing is biased towards the sheath housing. When the shuttle housi ng is biased forward, a generally tubular shuttle tube 44 in the shuttle housing opens th e slit in the elastomeric valve. The device is constructed so that, within the shuttle hou sing, hemostasis is provided after the shuttle tube has biased the elastomeric valve open.
