Transforming Patient Lives
Through Incisionless Surgery
What isEssential Tremor?
Essential Tremor ET is a neurological condition that causes shaking of the hands, head and voice, but it can also cause the legs and trunk to shake. Some people even have a feeling of internal tremor. The tremor begins mild and progresses over time to become more severe – and in some patients severe enough to interfere significantly with daily activities, such as eating, dressing, writing, etc. Essential tremor is associated with movement while doing actions and is not present at rest.
The primary symptoms associated with essential tremor include:
Uncontrollable shaking that occurs for brief periods of time
Begins gradually, usually on one side of the body
Occurs in the hands first, affecting one hand or both
Can include a shaking voice or tremor of the head
Worsening during periods of emotional stress and purposeful movement
Balance problems (in rare cases)
Patients living with Essential Tremor or Tremor-dominant Parkinson's Disease are being treated on a regular basis at more than 60 leading global medical centers. More than 4,000 patients around the world have been treated with Insightec's Exablate Neuro system.
It is the first and only platform that uses Focused Ultrasound to precisely treat deep in the brain in a single outpatient procedure with no incisions, implants or radiation during the treatment.
What is the Focused Ultrasound treatment?
During the treatment, the patient’s head will be positioned in the focused ultrasound helmet which is filled with water to maintain scalp temperature and facilitate transfer of the ultrasound waves. Ultrasound waves pass through the skull and are focused on a specific target in the brain. After each application of ultrasound energy, the patient will be asked to do tasks such as drawing spirals. This is so the physician can evaluate the improvement of the tremor and any potential side effects. When the location is confirmed and the therapeutic effect is confirmed, the temperature at the target is raised high enough to create a small ablation, or burn and provide a therapeutic effect, reducing the hand tremor.
The MRI scanner provides images for the physician to clearly see the treatment area and to show changes in temperature at the target. The medical team will be in the control room and the patient will be conscious and able to communicate with them.
Although individual results may vary, the patient should notice improvement during the treatment itself.
At the end of the procedure a final MRI scan will be done to assess the treatment. The frame will be removed and the patient taken to a recovery room. The treating physician will
determine when the patient can go home and when they will need to return for any follow-up visits. Within days patients typically return to normal activities.
