Abstract

In one example, a sensor is configured to be implanted into a patient's body. The sensor has at least one sensing element, a measurement device in communication with the at least one sensing element,and an internal wireless communicator in communication with the measurement device. The at least one sensing element includes a resistor, and the measurement device includes a capacitor. The measurement device measures a discharge time of the capacitor through the resistor so as to generate a measurement value that is proportional to a value of an anatomical property of the anatomical body, such as strain, that is observed by the sensor. The internal wireless communicator wirelessly communicates the measurement value through skin of the patient to an external wireless communicator situated outside of the patient's body.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application Serial No. 62 / 541,924, filed August 7, 2017, the disclosure of which is hereby incorporated by reference as if set forth in its entirety. technical field [0003] The present invention relates to sensors implantable in a patient's body, and to systems and methods for using the same. Background technique [0004] Tracking physical disease and healing in humans often involves measuring anatomical properties of the patient's body. However, some measurements, such as those that can only be obtained in vivo, may be difficult to obtain. Recently, sensors that can be implanted in a patient's body to track a patient's health over time have received attention. For example, attempts have been made to track the healing of damaged or fractured bones using one or more strain gauges. The one or more strain gauges are attached to the orthopedic implant, which in ...
