High-low intensity focused ultrasound treatment apparatus
A high-low intensity focused ultrasound treatment apparatus according to the present disclosure includes a plurality of ultrasound sources, and a controller to control a center frequency and intensity of focused ultrasound outputted from the ultrasound sources, wherein each of the ultrasound sources includes a first ultrasound transducer to output low-intensity focused ultrasound to detect a lesion, and a second ultrasound transducer to output high-intensity focused ultrasound to ablate or remove the detected lesion. The low-intensity focused ultrasound outputted from the first transducer may be used to detect a lesion in a patient's brain by applying a stimulus to the brain, and at the same time, investigating a response, and the high-intensity focused ultrasound outputted from the second transducer may be used to ablate or remove the detected lesion by applying a thermal or mechanical stimulus to the lesion.

METHOD FOR TREATING SECONDARY PULMONARY HYPERTENSION
Method for ameliorating secondary pulmonary hypertension in a patient including determining a pulmonary vascular resistance (PVR) of the patient suffering from secondary pulmonary hypertension; assessing a change in the PVR in response to a selection treatment; and treating the patient with a pulmonary artery manipulation device to provide pulmonary artery denervation if the patient is determined to suffer from fixed PH, thereby ameliorating the secondary pulmonary hypertension of the patient.
DAMAGING CANCEROUS CELLS UTILIZING RADIO FREQUENCY WAVES IN HEATING WITH HEATING ENHANCED BY INFUSION OR INJECTION OF GLUCOSE
A method for killing or damaging cancerous cells in a living body comprising introducing glucose or other organic material as a biasing component into heating cancerous cells for purposes of destroying the cancerous cells with a second method of heating, such as by bombardment of energy from an external electromagnetic source, so as to raise the temperature of the tumor or cancerous cells to a degree that they are damaged or expire.

Modulation of neural activity in the superior laryngeal nerve (SLN) or cervical sympathetic trunk (CST) is effective in treating diseases and conditions mediated by thyroid and parathyroid hormones, in particular diseases associated with calcitonin secretion (e.g. osteoporosis) or diseases associated with thyroxine secretion (e.g. hypothyroid syndrome).
DIFFERENTIAL PREDICTION OF ABERRATION CORRECTIONS FOR ULTRASOUND THERAPY
Various approaches for delivering ultrasound energy to a target region during a therapeutic or diagnostic procedure includes implementing an adjustment mechanism having a machine-learning model that has been trained, based on input vectors corresponding to a difference and/or a ratio of parameter values between multiple transducer elements, to generate, for each of the transducer elements, one or more parameter value to compensate for expected beam aberration resulting for an intervening tissue; and activating the transducer elements in accordance with the corresponding parameter values so as to generate an optimized focal zone at the target region during the therapeutic or diagnostic procedure.

Systems and methods for monitoring patient motion via capacitive position sensing
Systems and methods are described for the monitoring of patient motion via the detection of changes in capacitance, as measured using a capacitance position sensing electrode array. The changes in capacitance may be processed to determine a corresponding positional offset, for example, using a calibration data set relating capacitance to offset for each electrode of the array. The detected positional offset may be employed to provide feedback to a surgeon or operator of a medical device, or directly to the medical device for the control thereof. A medical procedure may be interrupted when the positional offset is detected to exceed a threshold. Alternatively, the detected positional offset may be employed to manually or automatically reconfigure a medical device to compensate for the detected change in position. Various configurations of capacitive position sensing devices are disclosed, including embodiment in incorporating capacitive sensing electrodes with a mask or other support structure.
