LASER ABLATION SYSTEM FOR TISSUE ABLATION

摘要

A system for ablation of tissue has at least a guideplate having a front surface and a rear surface. The guideplate has multiple guideholes distributed over the front surface and passing from the front surface to the rear surface. The at least three longitudinally advancing laser emitters are on elongated supports. The at least three longitudinally advancing laser emitters on elongated supports have a diameters that allow their passage through the guideholes on the guideplate. Each of the three laser emitters has a projection area for emission of laser energy; and the projection areas for each of the three laser emitters overlapping only a portion of the projection areas for at least two others of the three laser emitters when the at least three laser emitters lie within a single geometric plane. Moving the laser emitters while active devascularizes changing volumes of tumor tissue.
