20090036999 | Liner for prosthetic and orthopedic systems - 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. | 02-05-2009 |

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. | 02-07-2013 |
20130289741 | PROSTHETIC DEVICE, SYSTEM AND METHOD FOR INCREASING VACUUM ATTACHMENT - A prosthetic device, system and method is arranged to generate negative pressure inside a prosthetic socket. A pump mechanism is connected to a prosthetic foot and has a fluid chamber in fluid communication with the prosthetic socket during gait for drawing air from the prosthetic socket in step phase, and expelling air into the atmosphere in swing phase. The vacuum assisted suspension results in secure and intimate suspension as the negative pressure formed inside the prosthetic socket holds a residuum firmly to walls of the prosthetic socket. The vacuum is preferably formed at the distal area of the prosthetic socket, and sealed by a suspension liner having a seal component. | 10-31-2013 |
