  • Publication number: 20090264764
    Abstract: An enhanced intraluminal flow measurement system and method is conducive for a low-power ultrasonic system that can use continuous-wave (CW) Doppler sensing and wireless RF telemetry. Applications include measurement of blood flow in situ in living organisms. Implementations include an extraluminal component located outside of a body, such as a human or animal body, containing a lumen. The extraluminal component can be wirelessly coupled via an RF magnetic field or other RF field to an implantable intraluminal component. The intraluminal component (i.e. implant) is implanted inside of the lumen of the body such as a heart or elsewhere in a vasculature (such as in a dialysis shunt). The intraluminal component can telemeter, via RF electromagnetic signals, flow data directly out of the body housing the intraluminal component to be received by the extraluminal component.

  • Patent number: 7568394
    Abstract: An enhanced pressure sensing system and method use an external diaphragm to address issues involved with accurate and prolonged measurement of fluid pressure, such as of blood flowing in a vascular structure. Some external diaphragms include a metallized layer or other highly impermeable layer to furnish a high degree of seal at least near to hermetic grade. As temperature of the intermediary fluid changes, the external diaphragm is able to move in a direction that minimizes differential pressure across the external diaphragm over an operational temperature range thereby reducing pressure change of the intermediary fluid due to change in temperature of the intermediary fluid. Relatively smooth hydrodynamic surfaces can be used as well as a bi-layer construction.

  • Publication number: 20090093761
    Abstract: Many medical procedures, such as needle-sticking, could benefit from an assistive device that improves the optical contrast of externally targeted features and lumens of interest residing in and underneath the skin and/or exposed organ tissues. The inventive inexpensive device and method are useable on such externally targeted features and lumens while also protecting the practitioner and freeing up both of his/her hands, if necessary, to thereby eliminate practitioner self-sticking problems. The present device provides good optical contrast and also provides splash-protection against HIV, hepatitis and other blood-borne diseases. The inventive device method and apparatus may also include vibratory subcutaneous electrical nerve stimulation (TENS), drug-based or heating treatment capabilities for reducing pain, both perceived and real pain, associated with a device guided procedure. Finally, the pain reduction mechanisms have also been found useful for lumen dilation.
