First Claim
Patent Images
1. A foot compression system, comprising:
- a retractable, non-bendable pressure pad;
a spring coupled to the pressure pad, the spring configured to move the pressure pad into contact with a foot; and
a mechanism coupled to the spring, the mechanism operable to move the pressure pad out of contact with the foot by storing energy in the spring,wherein the foot compression system is completely contained within an item of footwear.

Abstract
Methods and systems for dynamic compression of venous tissue enable improved blood movement in the extremities. In accordance with an exemplary embodiment, a pressure pad provides a compressive force to a portion of the human body. The pressure pad is successively withdrawn and re-pressed against the body. In this manner, prevention and/or treatment of various medical conditions may be achieved, for example restless leg syndrome, edema, plantar fasciitis, deep vein thrombosis, pulmonary embolism, venous insufficiency, wound care, and/or the like.

13. A method, comprising:
-
extending, via a spring, a retractable, non-bendable pressure pad into contact a first time with the venous plexus region of a foot to apply pressure to the venous plexus region of the foot, wherein the pressure pad and the spring are both completely contained within an item of footwear; holding the pressure pad in contact with the venous plexus region of the foot for a period exceeding a selected duration; retracting, via an electric motor coupled to the spring, the pressure pad out of contact with the foot by at least one of compressing or twisting the spring; and extending, via the spring, the pressure pad into contact a second time with the venous plexus region of the foot. - View Dependent Claims (14, 15)

16. A method of treating or preventing a medical condition selected from a group comprising deep vein thrombosis, edema, restless leg syndrome, venous insufficiency, plantar fasciitis, pulmonary embolism, or a wound, comprising:
-
moving, by a spring, a pressure pad a first time to bring the pressure pad into contact with a portion of a human body to compress the portion of the human body; moving, by a mechanism, the pressure pad a second time to bring the pressure pad out of contact with the portion of a human body to allow the portion of the human body to at least partially refill with blood; moving, by the spring, the pressure pad a third time to bring the pressure pad into contact with the portion of the human body to compress the portion of the human body, wherein the spring, the mechanism, the pressure pad, and a power source for the mechanism are located entirely within an item of footwear. - View Dependent Claims (17)
