Abstract: A medical device system and method provide an RF electrosurgical generator coupled to an electrosurgical electrode via a patient box disposed in close proximity to the patient. An RF signal is delivered from the generator to the patient box where signal power is increased and the RF signal delivered to the electrosurgical electrode. The patient box is coupled to the electrosurgical electrode by a short cable capable of carrying an HV, high frequency 5 MHz signal without leakage. An electrical characteristic associated with the electrosurgical electrode is monitored and a desired RF power output and duty cycle maintained by adjusting DC input voltage applied to an RF amplifier, responsive to the monitoring. The system determines when the electrosurgical cutting electrode has started cutting and switches from a start mode to a run mode having a different RF duty cycle and a reduced RF power output controlled by a servo system.

Abstract: A biopsy system is disclosed that has a tissue removal system, an imaging system, an image display system and a common input console for these systems. The tissue removal system can have a mechanical tissue cutting blade or an electrosurgical cutting element and the tissue removal system is capable of handling both tissue cutting configurations. The imaging system is preferably an ultrasound imaging system and the image display system has a video screen for displaying diagnostic ultrasound images from an ultrasound probe. The common input console preferably has a touch screen display and a keyboard to facilitate operation of the tissue removal system, the ultrasound imaging system and the image display system from the same console.

Abstract: A graphical user interface is disclosed for a tissue biopsy system having a tissue cutting member adapted for cutting one or more tissue specimens from tissue at a target site within a patient. The graphical user interface includes a first GUI area representing a first region of the target site from which the tissue cutting member has separated one or more tissue specimens. The graphical user interface further includes a second GUI area, visually distinguishable from the first GUI area, representing a second region from which the tissue cutting member may separate one or more additional tissue specimens from tissue at the target site.
