    摘要: The disclosure describes techniques of reducing or eliminating a commonality between two modules within the same implantable medical device. Each module within the implantable medical device provides therapy to a patient. The commonality between the two modules exists due to at least one common component shared by the two modules. The commonality between the two modules may create common-mode interference and a shunt current. In accordance with this disclosure, various isolation circuits located at various locations are disclosed to reduce or eliminate the commonality between the two modules. The reduction or elimination of the commonality between the two modules may reduce or eliminate common-mode interference and the shunt current.

    摘要: An implantable medical sensor system provides signals representative of a magnitude of moment fraction applied to a sensor module at a selected site. A sensor module includes a first transducer producing a first signal having an associated first response to pressure and strain applied to the sensor module and a second transducer producing a second signal having an associated second response to pressure and strain applied to the sensor module. A moment fraction is computed in response to the first signal and the second signal. In various embodiments, the moment fraction is used to guide positioning of the sensor module, indicate a need for repositioning the sensor module, report loading of the sensor module during normal operation for use as sensor design information and in setting sensor calibration ranges.
