Focused Ultrasound Therapy

Outside Approval SquareFocused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with hypertension. This novel technology focuses beams of ultrasonic energy precisely and accurately on renal nerves without damaging surrounding normal tissue.

How it Works
Where the beams converge, the ultrasound produces precise ablation (thermal destruction) of the renal nerves which cause hypertension.

The primary options for treatment of hypertension include medication, but many have side effects which limit therapy effectiveness.

Clinical Trials SquareFor certain patients, focused ultrasound could provide a noninvasive and potentially more effective alternative to current medical management. Focused ultrasound is noninvasive, so it may be able to help lower blood pressure without the side effects of medication. It can also be repeated, if necessary.

Clinical Trials

At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of hypertension.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for hypertension has the CE Mark in Europe. It has not been approved by the FDA and is not covered by medical insurance companies in the US.
