FEEDBACK DEPENDENT LITHOTRIPSY ENERGY DELIVERY

摘要

To provide a lithotripter that includes a lithotripsy apparatus for treatment of a urinary tract stone by fragmentation.SOLUTION: The lithotripsy apparatus includes a lithotripsy wave guide shaft configured to transmit an energy form to at least one urinary tract stone. The lithotripter includes a sensing device configured to provide signal data for determining optimal application of energy during treatment with the lithotripsy apparatus. The lithotripter includes a processor configured to collect the signal data and provide feedback to a user. The processor has a control logic configured to determine at least one of: a) if the lithotripsy wave guide shaft is in contact with a tissue; b) if the lithotripsy wave guide shaft is in contact with a stone; c) a type of stone; d) if the user is applying force in excess of a predetermined threshold; and e) physical characteristics of a stone. A method is also provided.SELECTED DRAWING: Figure 1A
