Focused Ultrasound Therapy
Focused ultrasound is an early-stage, non-invasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with varicose veins. This novel technology focuses beams of ultrasound energy precisely and accurately on targets in the body without damaging surrounding normal tissue.
How it Works
Where the beams converge, the focused ultrasound produces precise ablation (thermal destruction) of the varicose vein. This enables varicose veins to be treated noninvasively.
The primary options for treatment of varicose veins are surgery, sclerotherapy, intravenous laser therapy, or radio frequency closure techniques.
For certain patients, focused ultrasound could provide a noninvasive alternative to these techniques with less risk of neurologic problems, phlebitis, wound issues, or other complications. It also requires no intravenous catheters, surgery, or anesthesia and can be repeated as needed.
A clinical trial in Austria has been completed. It explored using Theraclion's Echopulse device to noninvasively treat superficial and perforating varicose veins in the lower extremity. A publication is expected soon.
Regulatory Approval and Reimbursement
Theraclion has achieved the CE Mark in Europe for its SONOVEIN® system after successful clinical trials.
Focused ultrasound treatment for varicose veins is not yet approved by regulatory bodies in the US or covered by medical insurance companies.
