摘要： Treatment apparatus and methods for delivering energy at multiple selectable tissue depths as selected by a clinician. The treatment apparatus (10) includes at least two electrodes (56, 60) that are electrically isolated from each other, which permits each electrode to be independently energized for selecting different treatment depths. The electrodes (56, 60) may be concurrently energized with high frequency energy of the same polarity in a monopolar mode to deliver energy at a relatively deep depth into a patient's tissue (24), or with high frequency energy of a different polarity in a bipolar mode to provide a shallower penetration depth. Alternatively, the depth of energy delivery may be modified by energizing less than all of the electrodes (56, 60). The electrodes (56, 60) may be energized with high frequency energy of different phase relationships to deliver energy concurrently in both monopolar and bipolar modes with the phase difference determining a depth of energy delivery.

摘要： The invention relates to an HF generator and to a method for limiting the output effective power of the HF generator, especially for performing HF surgical cutting and coagulation of human or animal tissue. According to the invention, the output voltage and the HF output current of the HF generator (1) are detected by at least two detector devices (2, 3), the peak values and the effective values of the HF output voltage and of the output current as well as the mean value of the output effective power of the HF generator are determined by an evaluation device (4), and the calculated mean value is compared to a defined maximum mean value of the output effective power of the HF generator by a comparison device (5). Afterwards, a modulation device (7) modulates the HF output voltage using a pulse-shaped modulation signal. A control device (6) controls the modulation device (7) in such a manner that the pulse duration of the pulse-shaped modulation signal and/or the pulse duration between the pulse-shaped modulation signals is modified in order to keep the peak value of the output voltage constant when the calculated mean value of the output effective power is greater than the maximum mean value of the output effective power. Alternatively, the HF generator (1) is equipped with a sensor for evaluating the intensity of electric arcs between an electrode connected to the HF generator and the tissue.

摘要： Apparatus and methods for removal of obstructive material from a stent by modified electrosurgical ablation; penetrating and steering a catheter through an obstructed lumen, and detecting objects within a body via electromagnetic detection. An electrosurgical device (10) having at least one electrode (14) is positioned within the stent (20), and current is supplied to the electrode (14) to ablate material within or around the stent (20). The device may be properly positioned within the stent by using ultrasound transducers, fiber optics, impedance sensing or otherwise. In another aspect, by ablating material asymmetrically and advancing a catheter into (1010) the resulting void, the catheter (1010) can be steered through occlusive material (1060). Further, a device (2010) may be inserted within the body of a patient to determine the presence and location of an electromagnetically detectable object within the body.

摘要： A radio-frequency ablation system is disclosed in which the power, voltage, or temperature delivered to multiple electrodes may be dynamically controlled, and in which the electrodes may be simultaneously energized in phase with each other to achieve a desired lesion pattern. The system comprises a multiple electrode ablation catheter, each electrode having a temperature sensor operatively associated therewith. Each electrode is energized by its own RF amplifier, and all of the electrodes are driven in phase with each other by a common sine wave oscillator. A feedback network controls the degree of amplification of the separate RF amplifiers. According to a further aspect of the invention, a modular power supply arrangement is disclosed which is configurable to dynamically control the power, voltage, or temperature delivered to multiple electrodes of a multipolar ablation device. An arbitrary number of electrodes may be simultaneously energized in phase with each other to achieve a desired lesion pattern using the modular power supply by providing a sufficient number of removable modules.

摘要： A dual-channel RF power delivery system for applying RF energy to dual electrodes (26) of an RF ablation device with independent control of the power level, frequency, phase, and time duration of the RF energy applied to each electrode to more accurately control the ablation of a target tissue. The power delivery system supplies a first controlled RF signal having a first power level, frequency, phase, and time duration to the electrode (26) of a first flexible stylet (18) and a second controlled RF signal having a second power level frequency, phase, and time duration to the electrode (26) of a second flexible stylet (19). The difference btween the first and second power levels and the temperature of the tissue between the first stylet (18) and second stylet (19) are monitored to control the ablation of the target tissue. The supply of the first RF signal is terminated when the monitored temperature of the first stylet (18) exceeds a first predetermined value and the supply of the second RF signal is terminated when the monitored temperature of the second stylet (19) exceeds a second predetermined value.
摘要翻译：一种用于将RF能量施加到RF消融装置的双电极（26）的双通道RF功率传送系统，其独立控制施加到每个电极的RF能量的功率电平，频率，相位和持续时间，以更准确地控制目标组织的消融。功率输送系统向第一柔性探针（18）的电极（26）和具有第二功率电平频率的第二受控RF信号提供具有第一功率电平，频率，相位和持续时间的第一受控RF信号，相位和持续时间到第二灵活探针（19）的电极（26）。监测第一和第二功率水平之间的差异以及第一探针（18）和第二探针（19）之间的组织的温度以控制靶组织的消融。当第二探针（19）的监测温度超过第二预定值时，当第一探针（18）的监测温度超过第一预定值并且第二RF信号的供应终止时，第一RF信号的供应终止，值。
