Suturing catheter and relative system for percutaneously reducing mitral insufficiency

A suturing catheter for reducing mitral insufficiency by applying suturing points percutaneously, comprising:

• a catheter body provided with a distal end and at least one internal lumen;
• at least one suture filament slidable in an internal lumen defined as a suture lumen, said at least one suture filament being U-folded with two free ends arranged at the distal end of the catheter body;
• a pair of suture needles, each of which is connected to a respective free end of the at least one suture filament;
• a pair of stylets slidable in an internal lumen defined as a catch lumen, each of which is provided with a distal end arranged at the distal end of the catheter body;
• a pair of catch needles, each of which is connected to a respective distal end of a respective stylet, wherein said catch needles and said suture needles are provided with a connecting portion that allows a catch needle to mechanically engage with a respective suture needle;
• and
• a lever connected to the distal end of the catheter body by a pin, said lever comprising:
• a stapling arm, containing said suture needles which, together with the catheter body containing said catch needles defines a catch zone for a flap of a mitral valve;
• and
• an opposite operating arm connected to a control mandrel by a joining means which, together with the catheter body, defines an operating zone of the lever.
