Abstract
An electromagnetically induced cutting mechanism provides accurate cutting operations on soft tissues. The electromagnetically induced cutter is adapted to interact with atomized fluid particles. A non-thermal tissue remover comprises an aspiration cannula housing a fluid and energy guide for conducting electromagnetically induced mechanical cutting forces to the site within a patient's body for aspiration of soft tissue. The cannula is provided with an aspiration inlet port adjacent the cannula distal end. The proximal end of the cannula is provided with fluid flow connection to an aspiration source. Separated soft tissue and fluid are aspirated through the aspiration inlet port and the cannula by an aspiration source at the proximal end of the cannula.
