IMPLANTABLE TELEMETRIC MEDICAL SENSOR AND METHOD

摘要

A telemetric medical sensor (50) for implantation in a patient's body for measuring a parameter therein is provided. The sensor (50) comprises a housing (52) and a membrane (56) at one end of the housing. The membrane (56) is deformable in response to the parameter being measured. A microchip (90) is positioned within the housing (52) and operatively communicates with the membrane (56) for transmitting a digital signal indicative of the parameter. The microchip (90) comprises an array (92) of photoelectric cells (95) for use with an LED (100) for transmitting light at the photoelectric cells. A shutter (62) is connected to the membrane (56) and moveable between the photoelectric cells (95) and the LED (100) in response to deforming of the membrane (56).
