    摘要： An apparatus and method for delivering a vessel plug into a wound or incision in a living patient are described. The apparatus includes an expandable porous mesh mounted at the distal end of an elongate catheter. The expandable mesh may be positioned within a blood vessel or a target organ and expanded. When the mesh member is in an expanded condition, the mesh can be positioned adjacent the opening within the vessel or organ and a vessel plug can be inserted into the wound. The expanded mesh prevents the advancement of the vessel plug into the vessel or target organ, thereby avoiding possible thrombosis or stenosis within the vessel at the wound or incision site. Occlusion of the blood vessel during treatment is avoided by providing the expandable mesh with a porous construction which allows blood or other body fluids to flow therethrough while the apparatus is being used within the body of the patient. Non-thrombogenic materials can be used to treat the apparatus to prevent significant coagulation on the device during its use.

    摘要： A removable single-user tongue shield that is releasably attachable to the dispensing opening of a metered dose inhaler. The tongue protector is shaped to conform to the upper surface of the tongue to cover the taste sensor areas, and to minimize contact of the medication spray with the tongue's surface. In this manner the user is protected from objectionable medication taste while the delivery of the medication into the trachea is unaffected by the protector.

    摘要： A hemostasis valve for a catheter such as a catheter sheath introducer comprises an elastomeric partition extending across an aperture in a hub carried by a catheter. The partition defines an annular, peripheral area which is secured to the hub. The partition further defines a second area positioned radially inwardly from the peripheral area. The second area is of substantially less thickness than the peripheral area. The partition further defines a central area positioned radially inwardly from the second area, the central area being of substantially greater thickness than the second area, and defining a slit therethrough to permit passage of the elongated member.

    摘要： An improved maximum expiratory pressure device and cough simulator including a flow tube having an integral mouthpiece at a patient input end, and a hinged door at an opposite or discharge end for sealing off the flow tube. The hinged door is held closed by a releasable trigger operable by the patient to release the door after pressure build up to simulate a cough. A foldable pressure monitoring port is provided to connect the maximum expiratory pressure device to a pressure gauge, if desired, for monitoring the expiratory pressure developed within the flow tube.
