NOVEL MEDICAL METHODS AND SYSTEMS INCORPORATING WIRELESS MONITORING
First Claim
1. A system facilitating medical diagnosis, the system comprising:
- implantable markers to wirelessly transmit a signal in response to a wirelessly transmitted excitation signal, when the markers are implanted in a body;
an excitation signal transmitter to transmit the excitation signal to the implanted markers;
a marker signal receiver to receive the response signal from each of the two implanted markers;
a marker signal processor to convert the received response signals into positional information, the positional information comprising a distance between the two markers;
an implantable sensing member;
an implantable sensing member signal processor adapted to receive signals from the sensing member, when the sensing member is implanted in the body;
an analyzer to receive the positional information and the sensing member signals, and to collate the positional information with the sensing member signals;
a positional information transmitter coupled to the marker signal processor and the analyzer; and
an implantable sensing member signal transmitter coupled to the implantable sensing member signal processor and the analyzer.

Abstract
Medical systems and methods incorporate monitoring of at least two implanted markers, each of which is adapted to wirelessly transmit a signal in response to a wirelessly transmitted excitation signal; the response signals are converted into positional information for the two markers. The systems and methods further incorporate both, or one of, an implanted sensing member and/or an implanted therapy delivery device. Signals received from the sensing member may be collated with the positional information. A therapy delivered from the therapy delivery device may be adjusted according to the positional information.
