Abstract: The disclosed invention is a unique, patient-friendly, laser-based tumor ablation system for the removal of malignant tumors of the prostate and, with modified delivery systems, may have application for other areas of the human body. The disclosed invention is an integrated, robotic treatment subsystem that takes advantage of the capabilities of the previously disclosed MedSci Detection, Mapping and Confirmation System, for the purpose of providing a patient friendly system and method for removing tumors detected by said diagnostic system. The invention is a laser-based endosurgical thermal treatment system that utilizes historical cancer mapping data together with real-time ultrasonic and other data to reliably target and control the eradication of cancer conditions. The system contains computer aided robotic control such that control of the boundary, size, position and orientation of the ablated volume of tissue has a tolerance of less than a millimeter.
