Device, system, and method for reducing mitral valve regurgitation

A method of treating mitral valve regurgitation in a patient, comprising:

• (a) inserting a sheath introducer in a femoral vein;
• (b) inserting a guide catheter to engage in a coronary sinus through a femoral sheath;
• (c) traversing a guidewire into an interventricular septum and exiting into the right ventricular (RV) cavity;
• (d) placing a guidewire catcher in the right ventricular cavity through the femoral sheath and grabbing the exiting guidewire;
• (e) pulling the guidewire out to the femoral sheath with the guidewire catcher so that the guidewire makes up a path of the femoral vein:
• inferior vena cava (IVC)-coronary sinus (CS)-right ventricular (RV) cavity-right atrium (RA)-inferior vena cava (IVC)-femoral vein;
• (f) connecting a proximal end of the guidewire to a cerclage rope with a tension lock device;
• (g) replacing the guidewire with the cerclage rope in place by pulling a distal end of the guidewire;
• (h) advancing an MLC device through the femoral sheath over the cerclage rope with a delivery system;
• (i) when the MLC device is on optimal tension, securing an anchor to keep the MLC device in place;
• (i) when the MLC device is in place, delivering a suitable tension through the tension lock device under a guidance of real time imaging such as echocardiogram;
• (k) cutting the cerclage rope by a cutting device.
