Extracorporeal Flow Abolition in Relation With Primary Insufficiency of Great Saphenous Veins (GSV) Using High Intensity Focused Ultrasound (HIFU) Generated by Sonovein: A Multi Center Prospective Pivotal Study

NCT05926830 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 70

No results posted yet for this study

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.

Conditions

  • Chronic Venous Insufficiency

Interventions

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.
