  • Patent number: 10456287
    Abstract: A therapeutic sock is formed from a knit sock body formed in a tubular shape and terminating in a closed toe portion, the toe portion being divided into a first compartment configured accommodating a big toe and at least one additional compartment for other toes. At least one of the compartments has a area of increased compression as compared to a compression in other areas of the sock. The area of increased compression can be disposed on the first compartment and extend longitudinally along a medial edge of the first compartment and/or can be disposed on the at least one additional compartment and extend laterally around a circumference of the at least one additional compartment.
    Type: Grant

  • Patent number: 9392874
    Abstract: A pressure reducing device for reducing pressure at bony prominences of limbs is disclosed. A preferred embodiment is formed of an elastic foam, having upper and lower portions similar to oppositely-facing square pyramids, but having four arced sides rather than flat sides, and where the four sides converge at their apexes to form a blunted peak. The cushion body is shaped and sized so as to reduce the loading and shearing forces over the bony prominences of limbs, thereby reducing pressure and to readily allow a user to move along the support surface and to change orientations (roll or lie on their side).
