Abstract: Assembly (10) for positioning an electrode assembly (16) for radiofrequency ablation, comprising a first linear motion guide (11) defining a first axis of motion (103) and comprising a first carriage (111) operable to move along the first axis of motion (103), an XY positioner (12) operable to move a second carriage (123) in a two-dimensional space defined by a second axis of motion (104) and a third axis (105) orthogonal to the second axis of motion. The XY positioner is positioned relative to the first linear motion guide (11) such that the second axis of motion and the third axis are orthogonal to the first axis of motion (103). A first coupling means (125, 14) couples the electrode assembly (16) to the second carriage (123). A second linear motion guide (13) defining a fourth axis of motion (106) is disposed such that the fourth axis of motion is parallel to the second axis of motion (104).

Abstract: A radio frequency (RF) treatment flexible endoscope, for the in depth destruction of tumors by endo luminal access, like in a lung, esophagus, colon, rectum, etc . . . The electrodes (2?,2?) working in bipolar mode, deploy laterally and in parallel from the endoscope main body (1), reaching a tumor deeply located in the organ parenchyma. The use of different disposable distal end portions (15) of the endoscope allows the deployment of the electrodes (2?,2?) at different distances one from each other, in order to fit the destruction are to the tumor's size and shape. The deployment of the parallel electrodes (2?,2?) from the endoscope's main body (1) is controlled by motor drives (4) or a mechanical handled system (3), in order to reach the tumor with near a millimeter precision.
