  • Publication number: 20170311789
    Abstract: The present disclosure relates to vision preservation systems for medical devices, such as cryospray devices for use with endoscopes. Exemplary embodiments provide a distal attachment in the form of a shroud or cap that mounts to the end of a flexible endoscope. A purging fluid supply mechanism is provided along the length of the endoscope, providing a channel for purging fluid, such as gas, to communicate between the endoscope tip and an external gas supply. The cap or shroud assembly incorporates a lens clearing flow field adjustment mechanism, such as nozzles, designed to direct warm (room temperature or higher) purging fluid across a lens at the scope tip. Another flow deflection mechanism, such as a guide or nozzle, may be included with the cap to direct purging fluid at an angle away from the lens. Gas, as an example, directed across and toward the lens purges moisture to avoid condensation on the lens and shears debris and bodily fluids away from the field of view.

  • Publication number: 20160038213
    Abstract: A method and system for automated and semi-automated predictable, consistent, safe, effective, and lumen-specific and patient-specific cryospray treatment of airway tissue in which treatment duration is automatically set by the system following entry of patient information and treatment location information into the system by the user, and treatment spray is automatically stopped by the system when the automatically selected treatment duration has been achieved as determined by the system.

  • Publication number: 20060293595
    Abstract: The present invention provides a system and method for ultrasound pulse shaping and output power adjustment using multiple drive pulses. The multiple drive pulses are width modulated to provide the required output signal power and wave-shape characteristics. Using multiple width-modulated pulses provides control over power output that is capable of being varied much more rapidly than using a conventional voltage modulated drive pulse. Additionally, the multiple drive pulses provide better control over unwanted harmonics than does a single drive pulse. These two advantages allow multiple width modulated pulses to increase the capabilities in ultrasonic imaging devices, thereby, allowing for rapid switching between imaging techniques having widely disparate power requirements so that composite diagnostic images may be constructed combining the diagnostic benefits the various imaging techniques have to offer.

  • Patent number: 6899103
    Abstract: A self-contained transportable life support system for resuscitation, stabilization, and transport of a patient has an environmentally controlled housing for receiving and supporting a patient and a plurality of medical devices disposed within the housing. A control circuit attached to the housing has at least a portion thereof extending to an external surface of the housing for regulating operation of the medical devices and environmental conditions of within the housing in response to monitored life support conditions of the patient.

  • Patent number: 6489001
    Abstract: A protective structure for thermal insulation and impact resistance, and especially suited for bonded application to the exterior of aircraft including spacecraft to protect the craft from high temperatures generated by exhaust gases and by atmospheric re-entry. The structure includes either a single ceramic tile component with a cover component comprising a fiber reinforced ceramic matrix composite encasing the tile component, or a plurality of ceramic tile components with a like single cover component encasing the plurality of tile components. Utilizing the structures as an external aircraft surface imparts a super hard exterior that functions to significantly prohibit impact and erosion damage while not compromising the desirable thermal insulation properties inherent to tile.
