The Exablate Model 4000 Type-1.0/1.1 Neuro system involves using an advanced, non-invasive technique currently approved by the Food and Drug Administration (FDA) to treat one side of your brain in a procedure called a thalamotomy (lesion the thalamus). This procedure involves performing an ablation (lesion) of an area of the thalamus (a region in your brain) essential for treating Essential Tremor. While treating one side of the brain works well for patients that have a tremor dominance on one side of their body, patients that are bilaterally (both sides) affected with Essential Tremor may desire a bilateral treatment. You are being offered this study because you have been diagnosed with Essential Tremor and previously completed an Exablate Index Procedure to treat your Essential Tremor. The Exablate Index Procedure was the first Exablate procedure that was performed to treat your essential tremor on your dominant tremor side.

You may be eligible for this study if you meet the following criteria:

• Conditions: Medical Research
• Age: 99 years or below
• Gender: All
