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.

Claims

1. A transcoronary sinus pacing system, comprising:

a. an elongate sheath having a distal end, a proximal end, a first lumen and a second lumen wherein the first lumen has a first lumen exit port distal to a second lumen exit port;

b. a pacing catheter configured to pass through at least a portion of the elongate sheath, and having a tip that is configured to perforate a coronary sinus, wherein the pacing catheter is configured to optimize early closure of the mitral valve when anatomically positioned within a heart; and

c. a right ventricular pacing device, wherein the right ventricular pacing device and the pacing catheter are capable of receiving energy from a cardiac stimulation device.

2. The system of claim 1, wherein the elongate sheath is steerable by a guidewire.

3. The system of claim 1, wherein the elongate sheath further provides a radiopaque marker.

4. The system of claim 1, wherein the elongate sheath has a teardrop cross-section.

5. The system of claim 1, wherein the pacing catheter is configured to reduce the time required to activate the left ventricle when anatomically positioned within a heart.

6. The system of claim 1, wherein placement of the pacing catheter is configured to occur irrespective of an anatomical position of a coronary sinus.

7. The system of claim 1, wherein the sheath is removable.

8. The system of claim 1, further comprising an imaging system.

9. The system of claim 8, wherein the imaging system correlates a recorded angiographic image and live fluoroscopic image.

10. The system of claim 8, wherein the imaging system correlates a recorded angiographic image and a live intravascular ultrasound image.
