Abstract: An apparatus is disclosed for thermal therapy in a male prostate patient. The apparatus includes a long tubular element that is to be inserted into a patient's urethra so that a first tip end of it reaches up into the patient's diseased prostate. The elongated portion includes a narrow cylindrical tube within which an ultrasonic array is disposed along the long axis of the cylinder. Fluid is pumped into and out of a treatment zone of said patient as needed to control a temperature of a region in said treatment zone. A motorized driver is used to controllably rotate said elongated portion and the ultrasound array therein about the long axis of the apparatus so as to deliver acoustic energy to said diseased tissue. Various control and monitoring components may be used in conjunction with the present apparatus to design, control, and terminate the therapy.

Abstract: An arthroscopic or other surgical system includes a handpiece and a probe. The handpiece carries a motor drive, and the probe has a proximal hub and an elongate shaft which extends about a longitudinal axis to a working end of the probe. The hub is configured for detachably coupling to the handpiece, and the motor drive is configured to couple to a rotating drive coupling in the hub when the hub is coupled to the handpiece. A first magnetic component is carried by the hub, and a second magnetic component is coupled to rotate with the rotating drive coupling.

Abstract: Disclosed herein are systems and methods for locating and identifying nerves innervating the wall of arteries such as the renal artery. The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The methods includes evaluating a change in physiological parameters after energy is delivered to an arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using said method. Also provided are catheters for performing the mapping and ablating functions.
