Abstract

Medical devices are provided, comprising a medical device and a sensor.

First claim

What is claimed is:

1. A medical device, comprising: 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.

2. The medical device according to claim 1 , wherein said medical device is sterile.

3. 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.

4. 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; and transferring the data from the memory to a location outside the medical device;
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.

5. A method for detecting and/or recording an event in a subject with a medical device, comprising the step of interrogating at a desired point in time an activity of one or more sensors within the medical device, and recording said activity;
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.
