Method

Neuravive is a procedure that uses FDA approved focused ultrasound technology (MRgFUS) to treat patients with essential tremor who have not responded to medication. MRgFUS uses conventional ultrasound beams, focused on a point inside of the brain, to destroy cells associated with the essential tremor. These beams are activated by the physician for short periods of time called sonications. These sonications generally last about 15 seconds at a time. Currently, MRgFUS is also used to treat uterine fibroids, bone metastasis, prostate cancer, and various other conditions.

This treatment approach requires no surgery or general anesthesia and results in minimal downtime. The procedure is performed as outpatient and does not require a hospital stay.

Procedure

The physician begins the procedure by planning and calibrating the treatment using low-energy sound waves that cause no damage to any tissue. This is necessary to make sure to achieve the desired accuracy of the system. Medium-energy sound waves are then used to verify the accuracy and ensure it is beginning to reduce the patient’s tremor without any side effects. This level of energy also does not cause damage to tissue. During this process, the medical team interacts with the patient through various questions and tasks to check progress on alleviating the tremor.

Once the location is properly identified, the energy level will be raised high enough to treat the desired area. Some patients report brief mild-to-significant pain or brief episodes of dizziness associated with the sonications.

After sonications are performed, the medical team again assesses progress on the treated tremor. At all points during the procedure, the patient has a button he or she can use to stop the sonications should it be necessary.

Summary

There are four major advantages to Neuravive: results are typically felt immediately, it is non-surgical, it requires no ionizing radiation, and it has minimal downtime for the patient. The procedure has low complication rates and an outstanding safety profile; for full safety and risk information, please click here. Because the method requires lesioning, the results are not reversible or adjustable.
