Valve replacement procedure

HVs (TAVI, Sutureless): Frames + Leaflets

Frame Inspection

Development of a new system based on optical sensors, which allows:

​

1. Digitizing animal pericardial tissues and automatically selecting the areas that can be used as "leaflets" in the manufacturing process of bioprosthetic coronary valves

​

• Carrying out the final inspection and certification of leaflets after laser cutting before sewing them to the metal frame
