Wirelessly powered sensors for orthopedic implants

Abstract

A surgical sensor system for collecting internal patient data comprises a prosthetic implant comprising a housing, a sensor disposed within the housing and an internal power device connected to the sensor; and an external interrogation device comprising a wireless power signal generator for activating with the internal power device of the prosthetic implant. A method of remotely interacting with a sensor device implanted in anatomy with an orthopedic device comprises generating a wireless powering signal, activating the sensor device with the wireless power signal, collecting sensor data from the sensor device, and wirelessly communicating the sensor data from the sensor device using a low-power wireless signal. A method comprises generating wireless powering signals within an operating room using an interrogation device, activating electronics within a sensor-enabled orthopedic device with the signals, collecting data from the electronics, and wirelessly communicating data from the electronics to the interrogation device.
