Cell necrosis apparatus |
摘要 |
A cell necrosis apparatus comprises an elongated delivery device including a lumen and an energy delivery device. The energy delivery device includes at least a first and a second RF electrode each with a tissue piercing distal portion. The first and second RF electrodes are positionable in the elongated delivery device in a compacted state and deployable from the elongated delivery device with curvature in a deployed state. The first and second RF electrodes exhibit a changing direction of travel when advanced from the elongated delivery device to a selected tissue site. At least one infusion port is coupled to one of the elongated delivery device, the energy delivery device, the first RF electrode or the second RF electrode.
