Filed:

Jan 25, 2001

Appl. No.:

09/769551

Inventors:

Hewlett Melton - Sunnyvale CA, US
James Fearnside - Lexington MA, US
Claudio Zanelli - Menlo Park CA, US

International Classification:

A61N001/30
A61B017/20

US Classification:

604/021000, 604/022000

Abstract:

The effect of ultrasound irradiation of a human or other animal body portion is enhanced by operating the body portion as a trapped mode resonator. The intensity and location of resonances within the body portion is controlled by controlling such variables as the amplitude, frequency and/or phase of the ultrasound irradiation. This minimizes the overall energy required to be applied to the body portion in order to achieve a desired localized intensity level.

International Classification:

US Classification:

606/041000

Abstract:

Disclosed herein are devices for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having Chronic Obstructive Pulmonary Disease (COPD). More particularly, devices are disclosed to produce collateral openings or channels through the airway wall so that expired air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs.

International Classification:

G06F017/60

US Classification:

705/003000

Abstract:

The present invention provides a medical device, or medical navigator, based not on a programming perspective, but a use perspective. Medication to be taken is displayed on a color screen, actual size where possible. A color display is used because the pharmaceutical industry worldwide has substantially standardized on the colors; e.g., black and yellow pills mean barbiturates. Capsules and caplets are uniquely colored for the medicines. Pharmacists can readily tell what the medication is by looking at it. And, patients identify medications by their color and size. Input mechanisms are provided for indicating compliance with the mediation schedule and the physical condition of the patient.

International Classification:

A61B 812

US Classification:

12866206

Abstract:

An ultrasound system and method for intravascular ultrasonic imaging includes an array of beacons that are fixed to direct ultrasonic energy toward an imaging transducer, with individual beacons being identifiable in order to determine the angular position of the imaging transducer. Based upon the data related to beacon identification, operation of the imaging device is adaptively adjusted in order to compensate for variations in angular velocity of the transducer. Adaptive compensation may be performed by adjusting the pulse repetition rate of transmitted ultrasonic energy, by adjusting the scan conversion algorithm or mapping reflected ultrasonic energy, or by varying control of the drive structure for rotating the transducer. The beacons are preferably piezoelectrically active, but passive beacons may also be used. Position identification may be performed by techniques including amplitude sensing, phase sensing, pulse length sensing, and frequency sensing.

International Classification:

A61B 800

US Classification:

12866203

Abstract:

Spherical annulus piezoelectric transducers 62, 64 and spherical disc piezoelectric transducer 66 form a spherical shell having a radius of curvature R with a focal point 70 near the end of cladded-core acoustic waveguide 72. Each transducer 62, 64, 66 generates a bulk acoustic wave of a unique frequency and transmits it to focal point 70 where it enters core 74 of cladded-core acoustic waveguide 72. Alternatively, a conical annulus piezoelectric transducers 92, 116 on a prism 90 generate bulk acoustic waves of multiple discrete frequencies and focus them through cladding 75 and into core 74 of cladded-core acoustic waveguide 72. Surface acoustic waves of multiple discrete frequencies can be generated by multiple sets of curvilinear interdigital conductors 132, 134 on a piezoelectric substrate 122. The shape of curvilinear interdigital conductors 132, 134 focuses the surface acoustic waves at focal point 70 located near the end of acoustic waveguide 72. The surface acoustic waves are converted into bulk/longitudinal waves by either curvilinear corrugations 142, 146 or by a coupling medium that causes the surface acoustic waves to become leaky longitudinal waves.

US Classification:

Abstract:

A sensor for sensing in a gas stream a vapor of a liquid. The sensor includes a micropore and a wet temperature sensor. The micropore has an evaporation end and has a lumen to conduct liquid from a supply of the liquid for evaporation at the evaporation end. The wet temperature sensor has a heat sensitive part in contact with the liquid in the micropore. The heat sensitive part circumscribes the micropore and forms part of the lumen. Heat loss due to evaporation of the liquid when the wet temperature sensor wet with the liquid is placed in the gas stream will result in the temperature sensed by the wet temperature sensor being lower than the non-evaporative temperature of the gas stream. This lowering in temperature can be measured to determine the concentration of the vapor in the gas stream. An example of such a sensor has a thermocouple junction having micropores passing through the thermocouple junction.

International Classification:

A61B 812

US Classification:

12866206

Abstract:

An intracavity ultrasound diagnostic probe has a fiber acoustic waveguide that guides acoustic signals generated by a piezoelectric transducer located outside the body, through a body cavity and to an imaging site within the body where they reflect back into the ultrasound diagnostic probe that guides them back to the piezoelectric transducer located at the proximal end of the waveguide. The intracavity ultrasound diagnostic probe has one or more acoustic waveguides that could be optical fibers. The numerous advantages of placing the piezoelectric transducer outside the body include: electric power does not enter the body; a reusable piezoelectric transducer; the ability to use several acoustic signals at once including a mixture of doppler and imaging acoustic signals; the ability to adjust the frequency of each acoustic signal independently of the other acoustic signals to obtain the most desirable focus and resolution for a particular imaging site; and lower cost of complying with sterility regulations since they require discarding only the inexpensive fiber acoustic waveguide and the inexpensive catheter-radome.

Abstract:

A system and a method for remote monitoring of a designated user utilize an integrated scale that is able to measure the body weight of a current user and determine whether the current user is the designated user. The identification of the current user is accomplished by measuring a preselected length of the current user by reflecting sound waves at location(s) that defines the preselected length and comparing the measured length to a corresponding length of the designated user that is stored in the integrated scale. When the current user is identified as the designated user, the integrated scale transmits the measured body weight to a remote monitoring device. The preselected length may be the distance from the bottom of a foot to the knee joint. Alternatively, the preselected length may be the length of a tibia or femur, or the skeletal height. The integrated scale may include devices to measure the heart rate and the respiratory rate of the current user by transmitting sounds waves and recording reflected sound waves from the chest cavity and the heart chambers.
