Systems and methods for increasing implantable sensor accuracy
First Claim
1. A method for increasing accuracy of measurements produced using an implanted sensor implanted within a patient, where the measurements produced using the implanted sensor are affected by cycles of a cyclical body function, the method comprising:
- (a) obtaining an accurate measurement of a physiologic property for the patient;
(b) using the implanted sensor to produce a plurality of measurements of a same physiologic property as the physiologic property for which the accurate measurement is obtained at step (a);
(c) comparing the measurements produced using the implanted sensor at step (b) to the accurate measurement obtained at step (a) to thereby identify when relative to the cyclical body function the measurements produced using the implanted sensor are most accurate; and
(d) configuring the implanted system to thereafter use the implanted sensor to produce measurements of the same physiologic property when the measurements produced using the implanted sensor are most accurate as identified at step (c).

Abstract
Provided herein are implantable systems, and methods for use therewith, that increase the accuracy of measurements produced using an implanted sensor, where the measurements are affected by cycles of a cyclical body function (e.g., heart beat and/or respiration). In accordance with specific embodiments of system, a measurement that is presumed to be accurate is obtained. The measurement can be of a physiologic property, such as, but not limited to, blood oxygen saturation, hematocrit, or blood glucose concentration. Additionally, the implanted is used to produce a plurality of measurements of the physiologic property. Such measurements, produced using the implanted sensor, are compared to the measurement presumed to be accurate to thereby identify when the measurements produced using the implanted sensor are most accurate. Thereafter, the implanted system is configured to use the implanted sensor to produce measurements when the measurements produced using the implanted sensor are most accurate.

19. A method for increasing accuracy of measurements based on a sensor signal obtained from an implanted sensor of an implanted system implanted within a patient, where the sensor signal is affected by cycles of a cyclical body function, the method comprising:
-
(a) obtaining an accurate measurement of a physiologic property for the patient; (b) producing, based on the sensor signal, a plurality of measurements of the a same physiologic property as the physiologic property for which the accurate measurement is obtained at step (a); (c) comparing the measurements based on the sensor signal to the accurate measurement to thereby identify a portion of cycles of the cyclical body function when the measurements based on the sensor signal are most accurate; and (d) producing measurements based on a portion of the sensor signal that corresponds to the identified portion of cycles of the cyclical body function. - View Dependent Claims (20)

21. An implantable system, comprising:
-
an implantable sensor that can be used to produce measurements of a physiologic property, where the measurements are affected by cycles of a cyclical body function; and one or more processor configured to; compare measurements produced using the implanted implantable sensor to a separate accurate measurement of a same physiologic property to thereby identify when relative to the cyclical body function the measurements produced using the implantable sensor are most accurate; and thereafter use the implantable sensor to produce measurements of the same physiologic property when the measurements produced using the implantable sensor are most accurate as identified. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
