1. A cell necrosis apparatus, comprising:
- a flexible introducer including a lumen and a distal end sufficiently sharp to penetrate tissue;
an energy delivery device including a first RF electrode with a tissue piercing distal portion and a second RF electrode with a tissue piercing distal portion, the first and second RF electrodes being positionable in the introducer as the introducer is advanced through tissue and deployable with curvature from the introducer at a selected tissue site in a lateral direction away from the periphery of the introducer the first and second RF electrodes including in a deployed state a first curved section, a perpendicular section and a second curved section .

Abstract
A cell necrosis apparatus has a flexible introducer including a lumen and a distal end sufficiently sharp to penetrate tissue. An energy delivery device is positionable in the introducer as the introducer is advanced through tissue. The energy delivery device includes a first RF electrode with a tissue piercing distal portion and a second RF electrode with a tissue piercing distal portion. The first and second RF electrodes are deployable with curvature from the introducer at a selected tissue site in a lateral direction away from the periphery of the introducer.
