Abstract: A method and system for automated and semi-automated predictable, consistent, safe, effective, and lumen-specific and patient-specific cryospray treatment of airway tissue in which treatment duration is automatically set by the system following entry of patient information and treatment location information into the system by the user, and treatment spray is automatically stopped by the system when the automatically selected treatment duration has been achieved as determined by the system.

Abstract: Epicardial fat pad ablation is conducted using a catheter inserted through the chest wall, using ultrasound ablation, or using a catheter fitted with a directional ultrasound transducer and capable of being aligned with the epicardium. The epicardial fat pad locations are determined using noninvasive imaging methods, or using electrical maps. These locations are then displayed on maps or images of the heart, and thus targeted for minimally invasive or non invasive therapy. The methods of the present invention are less invasive than conventional methods of ablation, and permit flexible access to substantially any point on the epicardium.

Abstract: A system for minimizing neuromuscular stimulation includes a converter, an inverter, and a controller. The converter is configured to output a dc waveform and includes at least one first switching element operated at a first duty cycle. The inverter is coupled to the converter and includes at least one second switching element operated at a second duty cycle. The inverter is configured to invert the DC waveform to generate an electrosurgical pulse waveform. The controller is coupled to the converter and the inverter, and is configured to control the first duty cycle to adjust a magnitude of the electrosurgical pulse waveform and the second duty cycle to adjust at least one property of the electrosurgical pulse waveform to minimize neuromuscular stimulation.

Abstract: Targeted ablation of parathyroidal tissue is provided through hyperthermia adjuvant therapy. An in situ localization of parathyroidal tissue is obtained. A temperature-sensitive adjuvant is instilled into the parathyroidal tissue. Hyperthermia is therapeutically induced within the parathyroidal tissue. Heat-inducing energy is targeted into the parathyroidal tissue, which selectively includes the temperature-sensitive adjuvant. Application of the heat-inducing energy to the parathyroidal tissue is continued over a therapeutic range. In a further embodiment, the targeted ablation of the parathyroidal tissue is provided through hypothermia adjuvant therapy with the targeted use of cold-inducing energy.

Abstract: A combined cauterization and stent operation device for moving a stent to a lesion of a tubular tissue through a pipe member and performing a stent operation is provided that includes a bipolar electrode for cauterization configured to be disposed at an operation end of the pipe member to cauterize the lesion, and a high frequency generator configured to be connected to the bipolar electrode for cauterization to allow the bipolar electrode for cauterization to radiate a high frequency current.
