A Basivertebral Nerve Ablation (BVNA) System is a minimally invasive medical device system used to treat certain patients with chronic vertebrogenic low back pain by delivering radiofrequency (RF) energy to the basivertebral nerve (BVN) inside the vertebral body.
An assembly of battery-powered devices designed to regulate an electrical current used to heat the electrode tip or wire loop of a cutting instrument intended to burn or sear body tissues during surgery. It is typically used to stop bleeding (cauterization of blood vessels), to treat superficial skin lesions (e.g., removal of warts, removal of gastrointestinal polyps via an appropriate endoscope), or to occlude fallopian tubes during sterilization procedures. It typically consists of a generator, a handpiece, and electrodes. Unlike electrosurgical diathermy, electrocautery does not involve electrical current passing through the patient.
