External pulsation unit cuff
First Claim
1. A cuff for use in pulsation treatment of a patient wherein pressure is applied to and released from a patient'"'"'s blood vessels to stimulate blood flow correlated with a user'"'"'s physiological data based on data received from at least one physiological measuring device, comprising:
- a. a cuff having a first edge, a second edge, a third edge, a fourth edge, a top side and a bottom side, said cuff sized to fully encircle a body art of said user such that said bottom side contacts said user peripherally;
b. said cuff having at least one electromechanical actuator integral to said cuff, said actuator being proximate said first edge and fixedly attached to said top side, said actuator being rigidly attached to an actuator attachment, said actuator attachment being attached to a extension attachment, said actuator being distant from said extension attachment, said extension attachment being rigidly attached to said cuff at said top side proximate said second edge;
said actuator being controllably operable to a plurality of positions;
c. said plurality of positions being within a range of positions;
d. said range of positions ranging from an original position to a maximum constricted position;
e. said distance between said electromechanical actuator and said extension attachment in said original position being greater than said distance in said constricted position;
f. said cuff applying maximum positive pressure to said user'"'"'s blood vessels to constrict said blood vessels in said maximum constricted position of said plurality of positions of said actuator;
g. said distance directly related to each position of said electromechanical actuator in said range of positions;
i. said electromechanical actuator controllably operable from said relaxed position to any of said positions within said range of positions; and
j. said electromechanical actuator operable at variable frequency, at least one said frequency responsive to at least one said physiological datum.

Abstract
This invention is an improved medical device for non-invasive pulsation, including counterpulsation or simultaneous pulsation, treatment of heart disease and circulatory disorder through external cardiac assistance. The device is a cuff which is affixed on a patient'"'"'s lower body and extremities, and which constricts or expands by electromechanical activation, thereby augmenting blood pressure for treatment purposes. The cuff contains preferably fixed volume fluids such as gel, air, or water. The cuff envelops and is affixed to the patient'"'"'s lower body and limbs. In an alternative embodiment, the cuff creates a fixed volume of air between the cuff and the patient such that the cuff creates a vacuum when expanding, thereby stimulating return of blood to the constricted region, permitting better and/or faster responses.
