摘要: A high frequency electrosurgical power generator configured to produce electrical power at a frequency of about 1 to about 14 MHz and preferably having an essentially sinusoidal waveform with a voltage level up to 1,000 Vrms, and a current level up to 5 Amps. The output of the high frequency electrosurgical power generator is connected to an electrosurgical tool configured to receive the voltage and current produced by the electrosurgical power generator and deliver the voltage and current to an electrosurgical site. The output of the electrosurgical generator preferably is an essentially sinusoid waveform with a frequency between about 3 MHz and about 8 MHz, up to about 700 volts rms, up to about 2 amps, with a total power of up to 1,000 watts.

摘要: A device for accessing and for isolating a desired site within a patient's body, and for obtaining a body of tissue from a patient at the site that includes an electrosurgical cutting electrode near the distal tip of a shaft, an anchoring mechanism and an electrosurgical side-cutting device. Methods are provided for accessing a target site within a patient's body, anchoring a body of tissue at the site, and isolating the body of tissue at the site. The method may be performed for a surgical biopsy or lumpectomy at the target site within a patient's body.
