摘要： The inventive ablation element comprises an elongated cannula having a proximal end and a distal end. The cannula defines an internal lumen and a cannula axis. A plurality of conductors contained within the lumen, each having a proximal end proximate the proximal end of the cannula, and a distal end proximate the distal end of the cannula. A plurality of ablation stylets each has a proximal end and a distal end, and each coupled to the distal end of a respective conductor, the conductors together with their respective stylets being mounted for axial movement. A trocar point defined proximate the distal end of the cannula. A deflection surface positioned between the trocar point and the proximal end of the cannula, the deflection surface being configured and positioned to deflect at least some of the stylets laterally with respect to the cannula axis in different directions defining an ablation volume.

摘要： The inventive ablation element comprises an elongated cannula having a proximal end and a distal end. The cannula defines an internal lumen within the cannula and a cannula axis. A plurality of conductors contained within the lumen, each of the conductors has a proximal end proximate the proximal end of the cannula, and a distal end proximate the distal end of the cannula. A plurality of ablation stylets each has a proximal end and a distal end, and each coupled at the respective proximal end of the stylet to the distal end of a respective conductor, the stylets comprise a deflectable material, the conductors together with their respective stylets being mounted for axial movement. A trocar point defined proximate the distal end of the cannula.
