Clinical Trial Summary

This is a multi-center series assessment with a planned accrual of 70 patients with diagnosed symptomatic primary GSV insufficiency. Patients will be consented at a Pre-Study Visit and evaluated for eligibility and for baseline characteristics of the disease. Patients will receive treatment with Sonovein for the targeted segments of GSV. At follow-up visits at 7 days (1 to 10 days), 3 months (+/- 20 days), 6 months (+/- 25 days), and 12 months (+/- 30 days) changes in veins and flow characteristics will be evaluated by ultrasound, and patient well-being, including pain which will be evaluated by patient-reported VAS evaluations. Continued follow-up for a total of 12 months will be completed prior to subject study exit. Adverse events (AE) will be assessed at every study visit following HIFU treatment.

Intervention

Device:
Sonovein Treatment
The Sonovein System provides High Intensity Focused Ultrasound (HIFU) ablation of soft tissue. The energy is delivered via an extra-corporeal treatment probe, which includes an imaging system. The high-energy ultrasound waves propagate through the skin and are focused on a portion of the target tissue, generating intense heat and causing local cell apoptosis and progressive tissue volume reduction over the following months in the tissue. The process is then repeated in a stepwise fashion.

Outcome

Type Measure Description Time frame Safety issue
Primary Vein Occlusion Rate Percentage of limbs with occlusion of the treated vein (as measured by Duplex ultrasound) 12 months
Secondary Complications Number of limbs presenting complications and side effects resulting from the GSV intervention 12 months
Secondary Reflux-free Rate Percentage of limbs without reflux in the treated vein (as measured by Duplex ultrasound) 12 months
Secondary Venous Clinical Severity Score (VCSS) Assessment of venous disease (Scale 0-30: MIN=0 (least severe); MAX=30 (most severe)) 12 months
Secondary Clinical-Etiology-Anatomy-Pathophysiology (CEAP) Clinical signs and symptoms of lower limb venous disease (Scale C0-C6: MIN: C0=no visible or palpable signs of venous disease; MAX: C6=active venous ulcer) 12 months
