Title: (EN) Anchored RF ablation device for the destruction of tissue masses
Abstract: front page image
(EN) 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.
