Abstract
Abstract A device for aiding cardiocepital venous flow from the foot and leg of a patient including a first flexible fabric cuff for encircling the arch and instep of a patient's foot, a first bladder in the first cuff for placement in contiguous relationship to the arch, a second cuff for encircling the leg of the patient, a plurality of sequentially ascending second bladders in the second cuff for placement in contiguous relationship to the calf of the leg of the patient, a first conduit in communication with the first bladder, and second conduits in communication with the second bladders. A modification includes cuff structure for encircling the toes of the patient. A method for aiding cardiocepital venous flow from the foot and leg of an ambulatory patient comprising the steps of applying pressure to a plurality of areas of the foot and leg in a cardiocepital direction while maintaining the pressure on a preceding area until after it has been applied to a succeeding area before releasing the pressure on the preceding area, and maintaining the pressure on the most cardiocepital area on the leg while applying pressure to the least cardiocepital area on the foot before releasing the pressure on the most cardiocepital area.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
278 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient comprising the steps of applying pressure successively to only a single group of a plurality of adjacent areas of the soft tissue of said limb of said ambulatory patient in a cardiocepital direction, maintaining the pressure on a preceding less cardiocepital area of said single group of said limb of said ambulatory patient for a portion of the time that the pressure is applied to an adjacent succeeding cardiocepital area, relieving the pressure on each of said preceding areas of said single group after pressure has been applied to each succeeding area of said single group, said plurality of adjacent areas of said single group including a least cardiocepital area and a most cardiocepital area on said limb of said ambulatory patient and at least one area therebetween, maintaining said pressure on said most cardiocepital area of said single group on said limb of said ambulatory patient while applying pressure to said least cardiocepital area of said single group on said limb of said ambulatory patient, and relieving said pressure from said most cardiocepital area of said single group on said limb of said ambulatory patient only after pressure has been applied to said least cardiocepital area of said single group to thereby prevent reverse venous blood flow in an anti-cardiocepital direction beyond said least cardiocepital area of said single group from said areas of said single group to which said pressure has been applied previously and said relieving of said pressure from said most cardiocepital area of said single group permitting unrestricted blood flow beyond said most cardiocepital area in a cardiocepital direction.
Claim 2
Independent Claim
278 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient comprising the steps of applying pressure successively to only a single group of a plurality of adjacent areas of the soft tissue of said limb of said ambulatory patient in a cardiocepital direction, maintaining the pressure on a preceding less cardiocepital area of said single group of said limb of said ambulatory patient for a portion of the time that the pressure is applied to an adjacent succeeding cardiocepital area, relieving the pressure on each of said preceding areas of said single group after pressure has been applied to each succeeding area of said single group, said plurality of adjacent areas of said single group including a least cardiocepital area and a most cardiocepital area on said limb of said ambulatory patient and at least one area therebetween, maintaining said pressure on said most cardiocepital area of said single group on said limb of said ambulatory patient while applying pressure to said least cardiocepital area of said single group on said limb of said ambulatory patient, and relieving said pressure from said most cardiocepital area of said single group on said limb of said ambulatory patient only after pressure has been applied to said least cardiocepital area of said single group to thereby prevent reverse venous blood flow in an anti-cardiocepital direction beyond said least cardiocepital area of said single group from said areas of said single group to which said pressure has been applied previously and said relieving of said pressure from said most cardiocepital area of said single group permitting unrestricted blood flow beyond said most cardiocepital area in a cardiocepital direction.
Claim 3
Dependent Claim
53 words

Claim 4
Dependent Claim
37 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient as set forth in claim 1 wherein said pressure is applied to a plurality of areas between said least and most cardiocepital areas.
Claim 5
Dependent Claim
53 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient as set forth in claim 3 wherein said limb includes the foot and leg of said patient and wherein said least cardiocepital area is on the arch of said foot and said most cardiocepital area is on said leg.
Claim 6
Dependent Claim
33 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient as set forth in claim 4 wherein said plurality of areas includes a plurality of areas on said leg.
Claim 7
Dependent Claim
53 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient as set forth in claim 1 wherein said limb includes the foot and leg of said patient and wherein said least cardiocepital area is on the toes of said foot and said most cardiocepital area is on said leg.
Claim 8
Dependent Claim
41 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient as set forth in claim 6 wherein said pressure is applied to a plurality of areas between said toes and said most cardiocepital area on said leg.
Claim 9
Dependent Claim
34 words
A method for aiding cardiocepital venous flow from the limb of an ambulatory patient as set forth in claim 7 wherein said plurality of areas includes an area on the arch of the foot.
Claim 10
Dependent Claim
