Abstract

A device for draining a coronary sinus comprises a first catheter having a distal end, a proximal end, and a passage there through, the distal end adapted to be placed in a coronary sinus, a second catheter having a distal end, a proximal end, and a passage there through, the distal end adapted to be placed in a right side of a heart, and a control system for receiving signals indicative of a coronary sinus needing to be drained of blood, the control system comprising a pump for pumping blood from a coronary sinus through the first catheter to the second catheter into a right side of a heart.

Claims

1. A method of assisting drainage of blood from a coronary sinus comprising the steps of inserting a first catheter into a coronary sinus, inserting a second catheter into a right side of a heart, determining when blood needs to be drained from a coronary sinus to said right side of said heart, and pumping blood from a coronary sinus via the first catheter, through the second catheters and into said right side of said heart when it is determined that blood needs to be drained.

2. The method of claim 1 further comprising the step of inflating an inflatable cuff positioned at a distal end of the first catheter.

3. The method of claim 1 further comprising the step of deploying the first and second catheters through an interior jugular vein prior to inserting the first catheter into said said coronary sinus and prior to inserting the second catheter into said right side of said heart.

4. The method of claim 1 wherein the determining step further comprises the step of monitoring signals indicative of systole and diastole of said heart and starting and stopping pumping of blood from said coronary sinus to a right side of said heart depending upon the monitoring signals indicative of systole and diastole of said heart.

5. The method of claim 1 wherein said second catheter is inserted into an atrium on said right side of said heart.

6. The method of claim 1 wherein said second catheter is inserted into a ventricle on said right side of said heart.

7. The method of claim 1 further comprising the step of deploying the first and second catheters through a subclavian vein prior to inserting the first catheter into said coronary sinus and prior to inserting the second catheter into said right side of said heart.
