1. A method for removing hard tissue from a patient comprising:

  • providing a tissue remover having a proximal end and a distal end, and a fluid guide and an energy guide extending from the proximal end towards the distal end;

    inserting the tissue remover through an incision in the patient so that the distal end of the tissue remover is in proximity to hard tissue;

    transmitting gas and fluid through the fluid guide of the tissue remover;

    generating atomized fluid particles in an interaction zone located in close proximity to the distal end of the tissue remover by using the air and fluid transmitted through the fluid and energy guide;

    providing electromagnetic energy from an energy source to an electromagnetic energy transmitter operatively mounted within the fluid and energy guide; and

    transmitting the electromagnetic energy from an output end of the energy transmitter into the interaction zone, the electromagnetic energy having a wavelength which is substantially absorbed by a portion of atomized fluid particles in the interaction zone, the absorption of the electromagnetic energy by the portion of atomized fluid particles causing the portion of atomized fluid particles to expand and impart disruptive cutting forces onto the tissue in close proximity to the distal end of the tissue remover.
