1. A compression system for external counterpulsation comprising:
- at least three separate compression members for compressing the body of a patient, one of said compression members configured to be attached to a left thigh portion of a patient, one of said compression members configured to be attached to a right thigh portion of said patient; and
a plurality of retention members adapted to hold said compression members against the body;
wherein a total surface area of the at least three separate compression members comprises no more than 240 square inches;
wherein the compression system comprises two compression members configured to be attached to the buttocks.

Abstract
An external counterpulsation apparatus has an efficient cuff and bladder system. Embodiments of this system generally allow effective treatment at lower pressures and a reduced total body surface area being compressed. An accurate and reliable combination of automatic and preset timing for inflation and deflation of the bladder system is used to simplify use of the apparatus.

10. A method for performing external counterpulsation, comprising:
-
providing an external counterpulsation system having a plurality of activateable compression members, an energy source for activating said compression members, a physiological sensor and a compression member controller; attaching said compression members to a patient, said compression members comprising a first compression member located on a lower left thigh of a patient, a second compression member on an upper left thigh of a patient, a third compression member on a lower right thigh of a patient, a fourth compression member on an upper right thigh of a patient, and at least a fifth compression member on a buttocks portion of the patient; sensing heart activity in said patient; compressing said patient with said activateable compression members in synchrony with said heart activity; wherein said compressing step comprises the compression member controller sending a first signal to the energy source to send air to the compression members on the lower left and right thighs after a first delay, the compression member controller sending a second signal to the energy source to send air to the compression members in the upper left and right thighs after a second delay of approximately 40 milliseconds, and the compression member controller sending a third signal to the energy source to send air to the at least one compression member on the buttocks portion after a third delay of approximately 40 milliseconds. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
