Transcoronary Sinus Pacing System, LV Summit Pacing, Early Mitral Closure Pacing, and Methods Therefor

A left ventricular summit pacing system, comprising:

• a. an elongate sheath having a distal end and a proximal end and two lumen;
• b. a pacing catheter having a tip that perforates a coronary sinus and lodges in an LV summit;
• and
• c. a left ventricular summit pacing device engages the pacing needle.

An early mitral valve closure pacing system, comprising:

• a. an elongate sheath having a distal end and a proximal end and two lumen;
• b. a pacing catheter having a tip that perforates a coronary sinus and lodges in an LV summit to activate early mitral valve closure;
• and
• c. a pacing device configured to engage the pacing needle, wherein the pacing device operates in conjunction with a right ventricular apex pacing device.

A method for implanting a pacing device, comprising the steps of:

• a. introducing a sheath;
• b. steering the sheath to a target location within a coronary sinus;
• c. lodging a distal end of the sheath beyond a posterior summit of a left ventricle;
• d. advancing a pacing lead through a lumen of the sheath to the target location within the coronary sinus;
• e. perforating the coronary sinus with the pacing lead;
• f. coupling the pacing lead to cardiac tissue at the posterior summit of the left ventricular at a first end;
• and
• g. removing the sheath.

A method for achieving early closure of a mitral valve, comprising the steps of:

• a. introducing a sheath;
• b. steering the sheath to a target location within a coronary sinus;
• c. advancing a left ventricular pacing lead through a lumen of the sheath to the target location within the coronary sinus;
• d. perforating the coronary sinus with the left ventricular pacing lead;
• e. coupling the left ventricular pacing lead to a cardiac stimulation device;
• f. coupling a right ventricular pacing lead from a right ventricle to the cardiac stimulation device;
• g. removing the sheath;
• and
• h. activating the cardiac stimulation device to deliver energy to the pacing leads to achieve early closure of the mitral valve during systole.
