Abstract: An apparatus and method for conferring a therapeutic current on the heart and adjacent vasculature from externally positioned electrodes is provided. The apparatus includes a first electrode, a second electrode and a current generator. The method includes applying an electric stimulus to the heart and maintaining the timing and/or level of current to prevent unwanted depolarization.
Abstract: An apparatus and method for conferring a therapeutic current to the heart is provided. The apparatus includes a first electrode, a second electrode, a current generator and a controller. The apparatus may further include a sensor. The sensor is generally configured to measure field strength between the first and second electrode. The sensor may also monitor the cardiac cycle. The method includes applying an electric stimulus to the heart and sensing the electric field generated by the electric stimulus to prevent the level of current from inducing unwanted depolarization.

Abstract: This invention is an electrical stimulation apparatus for delivering an electrical field over a predetermined period of time to a targeted body tissue in order to stimulate a cell initiated angiogenic response in living cells within the targeted body tissue. The electrical stimulation apparatus includes an electrical field generating unit including a power support, a control mechanism interconnected with the power supply, and a plurality of electrodes designed to generate an electrical field proximate to the targeted body tissue. The amplitude of the electrical field delivered to or generated proximate to the targeted body tissue, and the duration of the period of delivery is sufficient to stimulate angiogenesis in the targeted body tissue.
