Publication number: 20140195008Abstract: A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, and having outer and inner surfaces. The liner sleeve includes an elongate, generally conical body portion formed from at least one material segment defining the liner outer surface. The at least one material segment being at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas. The liner sleeve includes a layer of polymeric material disposed on the at least one material segment and defining the liner sleeve inner surface, and a plurality of resilient seal elements protruding radially from the liner sleeve outer surface. The plurality of seal elements extend around at least one peripheral portion of the liner body portion. A pair of opposed annular recesses may be adjacently located above and below each of the at least one seal element.Type: ApplicationFiled: March 11, 2014Publication date: July 10, 2014Applicant: OSSUR hfInventors: Egill Sveinbjorn EGILSSON, Sigurdur ASGEIRSSON, Jenny Ruth HRAFNSDOTTIR, Grimur JONSSON

Publication number: 20130289741Abstract: 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.Type: ApplicationFiled: April 30, 2013Publication date: October 31, 2013Applicant: OSSUR HFInventors: Olafur Freyr HALLDORSSON, David SANDAHL, Bjarni GUNNARSSON, Egill Sveinbjorn EGILSSON

Publication number: 20130035770Abstract: 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: ApplicationFiled: September 12, 2012Publication date: February 7, 2013Inventors: Egill Sveinbjorn EGILSSON, Palmar I.

Patent number: 7632315Abstract: A vacuum chamber socket system having a shell which defines a receiving portion for receiving a residuum. The receiving portion is connected via a vacuum transfer port to a vacuum reservoir chamber. A one-way or non-return valve is provided within the vacuum transfer port for allowing air to pass from the receiving portion into the chamber, but not from the chamber to the receiving portion. The chamber also includes an evacuation port for creating a partial vacuum within both the chamber and the receiving portion. A removable evacuation device may be connected to the evacuation port in order to create the partial vacuum.Type: GrantFiled: October 2, 2007Date of Patent: December 15, 2009Assignee: Ă–ssur hfInventor: Egill Sveinbjorn Egilsson
