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: A system for recording, processing, and monitoring biosignals is provided, the system being configured to suspend data acquisition whenever an electric surgical tool or other generator of high frequency interference is in use. Such a system may protect the hardware of the system and reduce or eliminate the acquisition of distorted signals. The system of some embodiments includes an amplifier system configured to detect the presence of high frequency interference. Related methods are also disclosed.

Abstract: A system and method for fluid control in a thermal therapy system is disclosed. A fluid circuit permits passage of a fluid through a fluid circuit, including into and out of a treatment zone so as to cool or heat or maintain a temperature in said treatment zone at or near a desired temperature. The temperature is sensed at a point in the circuit between a discharge of a fluid pump and the treatment zone. MRI based thermometry of tissue in the treatment zone is accomplished in some aspects. Furthermore, a desired temperature may be programmably set to a given value or within a band of values using a processor and a temperature controller. In some aspects, leakage of fluid from a patient or from the fluid control system is captured by a leak-proof member to protect imaging and treatment equipment from damage.
