Patent number: 11969366Abstract: A liner is arranged for use in prosthetic and orthopedic devices. The liner defines first and second end portions, and inner and outer surfaces. The liner includes an inner layer having a frictional component and forms at least part of the periphery of the inner liner surface. The inner layer defines a plurality of apertures. A porous element is in communication with the inner liner surface and is connected to the inner layer such that the apertures permit a transfer of air from the inner surface to the porous element. A base layer adjoins the porous element and extends between the first and second end portions of the liner.Type: GrantFiled: February 22, 2022Date of Patent: April 30, 2024Assignee: OSSUR HFInventors: Egill Sveinbjorn Egilsson, Palmar I.
