ANCHORED RF ABLATION DEVICE FOR THE DESTRUCTION OF TISSUE MASSES

摘要

The inventive ablation element comprises an elongated cannula having a proximal end and a distal end defining an internal lumen and a plurality of conductors contained within the cannula. A plurality of ablation stylets are each coupled to the distal end of a respective conductor and are mounted for axial movement. A trocar point is defined proximate the distal end of the cannula and has a deflection surface positioned between the trocar point and the proximal end of the cannulafor deflecting, the stylets in a direction from the proximate end of the cannula to the distal end of the cannulato define an ablation volume.
