A medical device that can emulsify tissue with a heated fluid. The device may include an active heating element that is located within an inner channel at a distal end of a cannula. The cannula is adapted to be inserted into tissue such as a cornea. The active heating element can provide heat to a fluid that flows through the inner channel. The heat can be transferred into a bolus of fluid that is periodically generated by a pump. The heated bolus is then directed onto tissue.
