Radiofrequency Therapy Systems, Tissue Ablation, Nerve Fiber

Definition : Radio-frequency (RF) therapy systems used for selective ablation (therapeutic lesions) of nerve pain fibers. These systems, usually consist of a generator in the lower end of the RF spectrum (500 kHz or less is typical) and needlelike tubes as electrodes, usually with a length from 9 to 30 cm (3.5 to 12 inches) and a diameter from 12 to 22 G that are insulated except for the tip. Selective ablation of pain fibers is possible because they are small and do not have a lipid sheath (unmyelinated), making them less resistant to heat than motor and tactile nerve fibers. Pain nerve fiber ablation RF therapy systems are used to treat some chronic facial pains (e.g., trigeminal neuralgia) and other intractable pain, mostly in cancer patients, usually by ablation in the spinal cord (cervical cordotomy) or in the brain (cingulotomy).

IntraMedical Imaging LLC

Company Type: Parent

Intra-Medical Imaging LLC ("IMI") develops and markets molecular imaging instruments to- detect cancer during surgery, identify vulnerable plaques in arteries and to deliver cell and gene therapies. Molecular imaging is the most sensitive method of identifying abnormal tissues. The widespread application of molecular imaging in the operating room started with the advent of the sentinel node mapping for staging of melanoma and breast cancer. This technique is based on the injection of a radioactive tracer near the tumor site, and identifying the sentinel lymph nodes using a gamma detection probe.
