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.
