Abstract:
1. A medical device locating system for determining disposition of a sensor coil in a subject, said system comprising: a. an array of three or more triplet drive coil sets, each drive coil set including at least three discrete drive coils, each of the discrete drive coils being electromagnetic coils; b. at least one sensor coil adapted to provide one or more sensor coil response signals; c. a first system component that provides AC drive signals energizing said discrete drive coils; d. a second system component for measuring resulting one or more sensor coil response signals, including one or more of sequential single, paired or triplet sensor coil response signals; and e. a computing component for calculating sensor coil disposition in the subject relative to said triplet drive coil sets from one or more measured resulting sensor coil response signals.
