Summary

This is a one-arm, open label, prospective, single center study to evaluate clinical standardization with Theraclion's Sonovein 2 HIFU device. The original Sonovein device was tested in a clinical trial in 50 subjects and received CE Mark. That device has been updated yielding the current version of Sonovein 2. Based on the technical similarities between both devices in term of design, performance and principle of operation, the clinical data for Sonovein is sufficient to assure conformity of the Sonovein 2 with the respected essential requirements. At the same time, the compagny wishes to pursue the standardisation of the clinical practice with the second generation device and is, therefore, conducting this limited trial in 20 evaluable cases (from the planned 22 patients to be included). A "case" is defined as procedure conducted on a distinct vein.

Detailed description

The Sonovein 2 system provides high intensity focused ultrasound (HIFU) abaltion of soft tissue. The energy is delievered 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 within the focal area. The process is then repeated in a stepwize fashion to destroy the targeted tissues. The Sonovein 2 system is comprised of several components, including the console, treatment arm containing the visualization and treatment unit (VTU), a computer with touchscreen user interface. In addition, the Sonovein 2 system is intended to be used in conjunction with a disposable cooling and coupling system known as ePack.
