2. Fig. 1
The cuff was placed around vein to reduce its circumference at site of incompetent valve. A, Tags (arrows) were added to facilitate suturing of the device to surrounding fascia. Excess strap (A) allows adjustment of circumference and is trimmed once optimal circumference has been achieved (B).

Left, First sheep model was that of naturally incompetent valves in the external jugular vein (JV). Right, The Venocuff is shown around vein. Valve cusps have been brought into apposition and competence restored.

4. Fig. 3
Left, Second sheep model of valve incompetence produced by proximal arteriovenous fistula between exernal jugular vein (JV) and the common carotid artery (CA). Right, The Venocuff implanted to restore competence.

5. Fig. 4
The external jugular vein was occluded with Vesseloops 3 cm proximal and distal to valve (a). Blood was milked from distal into proximal segment of vein (b). Pressure was applied digitally to proximal segment of vein. Incompetence resulted in filling of distal vein (c).
