Infusion array ablation apparatus

A cell necrosis apparatus, comprising:

• an elongated delivery device including a lumen;
• an energy delivery device including at least a first and a second RF electrode, each electrode having a tissue piercing distal portion, the first and second electrodes (A) being positionable in the elongated delivery device in a compacted state and preformed to assume a curved shape when deployed, the first and second RF electrodes (B) exhibiting a changing direction of travel when advanced from the elongated delivery device to a selected tissue site, and (C) defining an ablation volume when in said deployed state, said device being adapted for operative connection to a source of RF energy for applying RF energy to said first and second RF electrode in said deployed state;
• and
• at least one of (a) the elongated delivery device, (b) the first RF electrode or (c) the second RF electrode being adapted for fluid delivery therethrough to an infusion port disposed on at least one of (i) the elongated delivery device, (ii) the first RF electrode or (iii) the second RF electrode.
