  • Patent number: 7036501
    Abstract: An oro-pharyngeal airway includes external air passages (28) formed between it and the facing surfaces of the patient's throat for continuous breathing by the patient. The open-ended passage (26) of conduit (24) transmits exhaled breath of the patient directly from the distal end of the airway at the larynx into the plenum (50) at the proximal end of the airway, and the breath is extracted radially from the plenum though the conduit section (34) and is analyzed by monitor (40). Alternatively, oxygen can be provided from source (42) through the converging conduit section (32) of the elongated body, and mucus, etc. can be aspirated from the larynx area of the throat by suction pump (44). These functions can take place without the need for additional intubation of the patient.

  • Patent number: 6974475
    Abstract: A prosthesis for use in preventing restenosis after angioplasty is formed of plastic or sheet metal, and is expandable and contractable for placement. The prosthesis can be inserted while in a collapsed position, then expanded and locked at the larger diameter. Spring force can be provided by the material itself, or metal springs can be embedded within the walls of the prosthesis. Preferably, the walls have holes therethrough to promote tissue growth; and, in one embodiment, the holes are in the form of slots so that the prosthesis is segmented and can bend longitudinally.

  • Patent number: 4372314
    Abstract: A dental sponge constructed of absorbent material, which may include portions of oxidized cellulose or gelatin sponge material to be used as a hemostatic aid, for controlling bleeding following oral surgery or tooth extraction. The absorbent material is provided with an impervious non-absorbent coating covering a substantial portion of said absorbent material, with the coating defining an opening exposing the absorbent material through which fluid can flow. The sponge can be constructed in a number of shapes, and can be provided with projecting tab means used for handling the sponge.
