| 摘要 |
The present invention provides systems, and methods for removing tumors, lesions or other undesirable body structures while minimizing the spread of viable cells from the tumor or lesion. An electro-surgical instrument (102), such as a probe or catheter, is positioned in close proximity to a viable body structure so that one or more electrode terminal (104) are brought into at least partial contact or close proximity with target tissue on the body structure. High frequency voltage is then applied between the electrode terminal (104) and one or more return electrodes to volumetrically remove at least a portion of the tissue cells through the disintegration of organic molecules into non-viable atoms, and molecules. The solid tissue cells are converted into non-condensible gases that are no longer intact or viable, and thus, not capable of spreading the viral or bacterial particles from the body structure. |
