Devices and methods for non-invasively improving blood circulation
First Claim
1. A method of applying therapeutic pressure to exterior pressure points on a patient to treat a medical condition, the method comprising the steps of:
- sensing the patient'"'"'s electrocardiogram and blood pressure and applying a selected magnitude of air pressure exteriorly to selected ones of the points on the patient during a selected time period during a cardiac cycle and controlling the peak diastolic pressure to peak systolic pressure ratio (D/S Ratio) in the treatment of persons with congestive heart failure and a left ventricular ejection fraction less than about 40% to not exceed the heart'"'"'s capacity to eject a therapeutic portion of the blood in the heart'"'"'s ventricles, wherein the D/S Ratio is held to not more than 0.7;
1 to 0.8;
1 during the first five hours of therapeutic pressure application.

Abstract
Circulatory assistance is provided in a non-invasive procedure safely and effectively using a microprocessor of an external counter pulsation device programmed to control the actuation of any or all of a plurality of valves, each of which is mounted on and in fluid communication with one of a plurality of individual inflatable bladders disposed in pockets within cuffs encasing the calves, thighs, buttocks, abdomen and/or chest of a person and an optional valve in fluid communication with the person'"'"'s airway, in any desired sequence or order, toward the heart or toward the feet, either during diastole or systole, at desired inception times during the cardiac cycle, for selected durations and at chosen pressures, for treating a variety of cardiac, non-cardiac and circulatory conditions.
