3 Fig. 1 View of the homologous valved segment in a vascular memory stent. Note: The anchoring barbs at the outside of the valved stent ascertain the desired position after embedding.

4 Fig. 2 Catheter delivery system with guidewire, pusher, and external sheath. Note: The valved stent (21-28 mm in length) was hand crimped onto the proximal portion (35 mm in length) of a catheter delivery system (into the proximal capsule between the arrows).

5 Fig. 3 Diagram of the hydrodynamic pulsatile-flow testing used for the in vitro testing of valved stents. The system enables the adjustment of compliance and resistance.

6 Fig. 4 In vivo evaluation of a homologous valved stent in the descending aorta under transesophageal echocardiography control. Note: There is good visualization of the laminar transvalvular blood flow (left) and the fully closed leaflets of the new valve (right). 1, Nitinol stent; 2, valve cusp.
