Patent ID: 8562549

Claim:
A compression device for applying compression to a part of a wearer's body comprising: an outer layer; an inflatable member including first and second fluid impermeable layers secured to one another to define an inflatable chamber, the inflatable member having a perimeter edge margin, wherein the inflatable member has a body portion configured to underlie a foot of the wearer and extend generally between the ball and the heel of the foot, and a wing portion extending laterally outward from the body portion, the inflatable member directly overlying the outer layer and being secured to the outer layer at the wing portion of the inflatable member, an entirety of the body portion of the inflatable member being free from direct securement to the outer layer; and a frame member that is a separate piece of material from the inflatable member and has a rigidity greater than a rigidity of the inflatable member, the frame member being secured to the inflatable member and extending along substantially an entirety of the perimeter edge margin of the inflatable member, the frame member imparting rigidity to the inflatable member so that rigidity of the inflatable member at the perimeter edge margin is greater than the rigidity of the inflatable member inside the perimeter edge margin.
