  • Patent number: 5313957
    Abstract: A physiological pressure transducer assembly mounted on a transvenously-insertable guide wire is disclosed. The multiple coils of the guide wire define an elongated tubular passage within which fiber optic leads are contained for the transmission of light signals to a pressure transducer. A window or aperture is cut along a restricted portion of the length of the guide wire coil to provide a pressure-sensing aperture over which an elastic, pressure-sensitive membrane is positioned. The coils of the guide wire adjacent to the sensing aperture are joined together for increased rigidity along the length of the pressure transducer assembly, as by soldering or brazing. A separate, cylindrical housing, preferably of molded plastic, is wholly contained within the reinforced length of the guide wire. The proximal end portions of fiber optic sending and receiving leads or paths are received and contained within the housing in a predetermined arrangement and geometry defining a light-transmitting gap.

  • Patent number: 5256133
    Abstract: Female stress urinary incontinence is corrected by implanting a correcting device which supports the urethrovesical junction from the abdominal fascia. A trocar/cannula assembly is inserted upwardly through the vaginal wall immediately adjacent or proximate the urethrovesical junction, through the space of Retzius, and through the abdominal fascia. The trocar is then removed from the cannula after which the correcting device is loaded into the cannula and pushed upwardly through it and to an implanted position using a push rod. Thereafter the push rod and cannula are removed to complete the procedure.

  • Patent number: 5226883
    Abstract: A ventilation cap for a flashback chamber is formed of a hollow elongate cylindrical body of polymeric material and includes a proximal opening which is blocked by a venting material such as a hydrophobic filter, and a distal opening which is sized to allow an extension of the flashback chamber to be inserted therein for airtight connection therewith. The elongate body of the ventilation cap has a tear strip formed therein by a pair of generally parallel score lines. The cap is affixed to the flashback chamber so as to allow air to pass from the flashback chamber through the vent as blood fills the flashback chamber, while preventing blood from passing through the vent. When it is desired to attach other apparatus to the extension of the flashback chamber, the tear strip, which may have a pull tab integrally formed therewith, is torn away from the elongate body to destroy the airtight seal between the flashback extension and the cap.

  • Patent number: 5201322
    Abstract: A device is disclosed for detecting the presence and direction of air flow through a passageway having a first opening and a second opening for air to flow therethrough in either a first direction or a second direction. The device comprises a piezoelectric sensor located within the passageway. A flow director is provided within the passageway for directing air flow through the passageway for impingement upon the sensor. The sensor generates a first electrical signal when air flows through the passageway in the first direction and a second electrical signal when air flows through the passageway in the second direction. A discriminator is electrically connected to the sensor for receiving the first and second electrical signals and for discriminating between the two signals to identify the direction of air flow through the passageway.

  • Patent number: 5195526
    Abstract: A radiographically opaque spinal marker needle having a lower portion consisting of a small bore hollow needle and an upper portion having a larger outside diameter. An intermediate penetration restriction member fixed to and surrounding the marker needle at a point proximate the junction of the upper portion and the lower portion limits the depth of penetration of the hollow needle into the patient or tissue, provides stability, and forms a large observable mass on an X-ray. In an alternative embodiment the larger upper bore portion is in the form of a syringe and includes a prefilled ampule of dye within the syringe for injection into the patient by a plunger assembly. The upper portion may be separable from the lower portion at a point above the pentration restriction member.

  • Patent number: 5185011
    Abstract: A reusable multiple layered waterproof diaper garment (11) features an outer layer (25) of garment cloth and is so made and assembled that when fitted to the child and wet by that child's excrement, moisture disposed onto the inner or first layer (55) will not travel through the middle or second layer (35) by way of stitch lines or material layer to expose the outer or third layer (25) to wetness. The middle or second layer (35) is made of waterproof, non-wicking launderable, machine dryable material which is breathable and of such a quality that, when seamed to itself along a separate line of its own surface or when seamed to a surface of a separate piece of similar material, is capable of being seam sealed and rendered liquid impermeable along the seam seal line (36). The first layer (55) is a launderable, machine dryable hypoallerginic cloth and may include multiple layers of such cloth and may include a core (47) of launderable, machine-dryable absorbent material.

  • Patent number: 5179958
    Abstract: A calorimeter for generating signals representative of the oxygen consumption of a subject over a test period includes a bidirectional volume flow sensor and a carbon dioxide scrubber connected to a mouthpiece. Interconnections are such that the air inhaled by the subject passes through the flow meter and the exhaled breath passes first through the carbon dioxide scrubber and then through the flow meter. The electrical output signals from the flow meter are provided to a microprocessor-based computer which integrates the volume differences between the inhaled gas, and the exhaled gas after the carbon dioxide has been removed from it, over the period of the test. Since the exhaled carbon dioxide essentially replaces the oxygen used by the subject during the test, this integral difference is a function of the patient's oxygen consumption. The use of a bidirectional flow meter results in a simple instrument that may be disposed after a single use to avoid the need for sterilization.

  • Patent number: 5178155
    Abstract: A calorimeter for generating signals representative of the oxygen consumption and carbon dioxide production of a subject over a test period includes two flow sensors and a carbon dioxide scrubber connected to a patient mouthpiece. Interconnections are such that the air inhaled by the subject passes through one flow meter and the exhaled breath passes first through the other flow meter the carbon dioxide the scrubber and then through the first flow meter. The electrical output signals from the flow meters are provided to a microprocessor based computer which integrates the volume differences between the inhaled gas, and the exhaled gas after the carbon dioxide has been removed from it, over the period of the test. The inhaled volume less that part of the exhaled volume which does not constitute CO.sub.2 measures the oxygen comsumption per breath, the integral difference is a function of the patient's oxygen consumption over the period of the test.
