    摘要： A vascular access device is provided that has a device lumen valve and a safety valve feature to prevent leakage of blood from a lumen of such device. The vascular access device includes a sheath which may have an outer tube and structure defining a device lumen located therein. The access device further includes a detachable device valve which provides sealing of the device lumen. In addition, a non-detachable hemostasis safety valve is provided on the proximal end of the device lumen to seal the device lumen when no device valve is present. The device valve attaches to and simultaneously opens the proximal end of the hemostasis safety valve. In one embodiment, the device valve includes a distal projection that pierces an elastomeric valve member of the hemostasis safety valve. The elastomeric valve member of the hemostasis safety valve is stiffer than an elastomeric valve member of the device valve, and prevents introduction of guidewires and highly flexible catheters therethrough.

    摘要： A cardiac output probe assembly is disclosed wherein the assembly includes a chest tube which carries a cardiac output probe therein. The chest tube includes a main lumen for draining fluids from the thoracic cavity of the chest and a secondary lumen which carries leads attached to the probe. The probe is attached to the pulmonary artery or aorta vessel with detachable tines and/or sutures. The tines are uniquely configured to ensure that good contact between the probe and vessel is maintained. When cardiac output monitoring is complete, a pulling force is applied to the probe leads extending out through a proximal end of the tube. The pulling force detaches the tines and sutures, releasing the probe from connection with the vessel. Further withdrawal of the leads through the tube retracts the probe within the tube, where it is housed until the tube is removed from the thoracic cavity.
