Devices, systems and methods for using and monitoring medical devices

A method, comprising:

• sensing a physical quantity using a medical device;
• and generating a representation of the sensed quantity;
• wherein the medical device comprises:
• an interbody spinal fusion device and a single Implantable Sensor Module (ISM), the single ISM comprising components disposed in a single housing, the components comprising a battery that provide a power supply to the ISM components, a sensor channel comprising a sensor configured to generate a sensor signal that represents a sensed quantity, a memory configured to collect and store data from the sensor, and a communication interface, the sensor channel comprising a power management circuit to manage transport of voltage from the battery to a sensor of the sensor channel via a conductor where the power management circuit is configured to obtain data from the sensor during repeated periodic intervals as a means to manage battery life, the sensor channel further comprising an oscillator, an amplifier, a signal conditioner, and a control circuit, the sensor comprising a sensor selected from at least one accelerometer and a gyroscope;
• the medical device further comprising an antenna configured to transmit the data from the memory to a remote device;
• wherein the ISM is located on an inner surface of the interbody spinal fusion device.

A method comprising:

• obtaining data from sensors positioned within a medical device of a subject;
• storing the data in a memory device located within the medical device;
