Abstract
A medical needle or cannula for stimulation or ablation includes a rigid bent tip for simplified placement at target sites within a patient's anatomy. The curved tip or shaft is used to steer the device within the patient's body and to avoid critical anatomical structures. The device is partially insulated and has a tip that is at least partially electrically exposed; a connection to an external signal generator provides electrical stimulation or high-frequency heating of the patient's tissue proximal to the exposed tip. The device includes a longitudinal passage to facilitate the injection of fluids or the insertion of instruments through the cannula or needle.
