Patent ID: 8062283

Claim:
A method of treating an infracted region of a patient's myocardium following an acute myocardial infarction, comprising: opening a blockage in a patient's coronary artery to relieve myocardial ischemia; providing a delivery catheter and a separate flow control catheter; deploying the delivery catheter in the patient's coronary vessel; delivering a solution containing stem cells, endothelial progenitor cells or mediators of stem cell mobilization, migration and attachment, into the coronary vessel via the delivery catheter; and deploying the flow control catheter in the patient's cardiac venous vasculature to partially or fully occlude blood flow through the patient's coronary ostium to create a backpressure within the patient's cardiac venous vasculature that controls a rate of blood flow through the infarcted region retaining of the stem cells in the infarcted region.
