Straight and curved electrodes specialized for radiofrequency heat lesioning of the retrogasserian trigeminal nerve for the treatment of pain from trigeminal neuralgia.

Steerable Trigeminal Radiofrequency Electrode (TEW)

The variable tip exposure and choice of either straight or curved tip geometries, enable the TEW electrode to selectively target the ophthalmic (V1), maxillary (V2), or mandibular (V3) division of the trigeminal nerve.  Invented by Dr. John Tew and Prof. Eric Cosman, Sr, the TEW electrode has been used to successfully treat Trigeminal Neuralgia pain in an outpatient procedure for over 30 years. A step-by-step procedure guide written by Dr. Tew is available.

Straight Trigeminal Radiofrequency Electrode (TIC)

With tip exposures ranging from 2 mm to 10 mm, the TIC RF electrode are designed to target a desired radiofrequency heat lesion volume in the retrogasserian Trigeminal nerve. Invented by Dr. William Sweet of the Massachusetts General Hospital (MGH) and Bernard J. Cosman, the TIC kit has been used to treat pain from Trigeminal Neuralgia for over 40 years.
