Transcoronary sinus pacing system, LV summit pacing, early mitral closure pacing, and methods therefor
First Claim
1. A method for implanting a pacing device, comprising the steps of:
- a. introducing a sheath;
b. steering the sheath to a left ventricular summit;
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 left ventricular summit;
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;
g. removing the sheath; and
h. activating the left ventricular summit to achieve early closure of a mitral valve during systole.

Abstract
A transcoronary sinus pacing system comprising a sheath having a lumen, a pacing catheter having a pacing needle, wherein the catheter can be advanced within the lumen and placed in the LV summit, and a right ventricular pacing device. A LV summit pacing device. An early mitral valve closure pacing device configured to operate with a right ventricular apex pacing device. A method for implanting a pacing device at a target coronary sinus tissue location, wherein the target can be the posterior LV summit. A method for achieving early closure of a mitral valve. A method for using visualization devices such as fluoroscopy or ultrasound and/or catheter features such as a radiopaque marker to locate a target location for LV pacing and to avoid piercing an artery or the pericardium when anchoring the LV pacing electrode.
