Abstract
Disclosed is an invasive intervertebral fusion cage, the intervertebral fusion cage including: a vibration sensor; and a frame configured to support surrounding tissues used to create a bone fusion process; wherein the vibration sensor is integral with the frame in order to measure the mechanical vibrations the vibrations arising from the medium consisting of the frame, the surrounding tissues and/or the fusionned bone, and wherein the intervertebral fusion cage does not include a vibration excitation transducer. Also disclosed is a remote medical monitoring device including a receiver for receiving data from an intervertebral fusion cage, reflecting the mechanical vibrations of a medium and a calculator computing from the received data a medium indicator by: determining at least one vibration pattern of the received data; comparing the at least one vibration pattern with at least one reference model; generating a medium indicator in function of the comparing step.
