High-frequency ablation medical device for pancreatic cystic lesion, having self-expanding spherical electrode embedded therein

Abstract

A radiofrequency ablation medical device includes: a guide catheter movable to a lesion site of an organ; and an electrode catheter disposed in the guide catheter to be inserted through and protrude out from an end of the guide catheter, and including a shape memory electrode for ablation of the lesion site, wherein the guide catheter includes: an outer tube; an inner tube having an outer surface spaced apart from an inner surface of the outer tube, and a catheter passage through which the electrode catheter is movable; and a suction channel formed between the outer tube and the inner tube to aspirate lesion fluid generated at the lesion site.
