Abstract
The present invention provides electrosurgical needles, needle systems, and methods for their use which will allow the surgeon to target a tumor's blood supply. Generally, the invention facilities targeting the bloodflow of the tumor by incorporating a doppler ultrasound transducer into the needle or needle sheath. Preferably, the surgeon will also be able to control the temperature of the needle using an integral temperature sensor to effect maximum transfer of the RF energy into the tissue, thereby maximizing the volume of tissue destroyed. Furthermore, when used (for example) in the treatment of uterine fibroids, the present invention will reduce damage to the serosa by monitoring the uterine surface temperature during myolysis through a temperature sensor integrated into the sheath holding the myolysis needle.
