Method and apparatus for coupling left ventricle of the heart to the anterior interventricular vein to stimulate collateral development in ischemic regions

摘要

A method for stimulation of collateral development in ischemic cardiac regions comprises the fluid coupling of the left ventricle of the heart to the anterior interventricular vein to stimulate collateral development in ischemic regions. The fluid coupling of the left ventricle of the heart to the anterior interventricular vein includes a control of the diastolic/systolic pressure in the venous system to be within about 20-50 mmHg. The fluid coupling of the left ventricle of the heart to the anterior interventricular vein includes inserting a transmyocardial conduit into the left ventricle and a tri-directional coupler attached to the anterior interventricular vein. An associated apparatus for stimulation of collateral development in ischemic cardiac regions via the fluid coupling of the left ventricle of the heart to the anterior interventricular vein is disclosed.

1. A method for stimulation of collateral development in ischemic cardiac regions comprising the step of:
providing a fluid coupling of a left ventricle of a heart to an anterior interventricular vein to stimulate collateral development in ischemic cardiac regions; and operating the fluid coupling between the left ventricle of the heart and the anterior interventricular vein at pressures to avoid damage to venous vasculature; wherein the step of providing a fluid coupling of the left ventricle of the heart to the anterior interventricular vein includes inserting a transmyocardial conduit into the left ventricle and further including a tri-directional coupler attached to the anterior interventricular vein.
