| 20090270740 | ENHANCED PRESSURE SENSING SYSTEM AND METHOD - 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. | 10-29-2009 |
| 20090264766 | ENHANCED INTRALUMINAL FLOW MEASUREMENT METHOD USING REFERENCE AND SHIFTED SIGNALS - 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. | 10-22-2009 |
