Publication number: 20140156026Abstract: 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: February 24, 2014Publication date: June 5, 2014Applicant: OSSUR hfInventors: Egill Sveinbjorn EGILSSON, Sigurdur ASGEIRSSON, Jenny Ruth HRAFNSDOTTIR, Grimur JONSSON

Patent number: 8679194Abstract: The expulsion liner is for use with a prosthetic device to be secured to a residual limb. The expulsion liner includes an elongated elastomeric tube having a closed distal end and an open proximal end, and defining an interior space configured to receive the residual limb. A one-way valve is positioned within the closed distal end and provides controlled fluid communication between the interior space and an external environment. The one-way valve may be configured to allow the weight of a user, via the residual limb, to expel moisture and air from the interior space out to the external environment.Type: GrantFiled: January 21, 2010Date of Patent: March 25, 2014Assignee: Evolution Industries, Inc.Inventor: Craig Mackenzie

Patent number: 8641779Abstract: A system for securing a residual limb having a sheath, thereabout and a strap emanating therefrom through the socket of a prosthetic limb or the like, utilizing a uniquely configured and operated lever which is specially designed for the task of pulling of the strap from the exterior of the socket to urge the residual limb therein. The system uses the tool, in pivotal communication with the prosthesis, to provide efficient pulling force with less effort, utilizing lever action. The preferred embodiment of the tool comprises an elongated body having specifically formed first and second ends, and has formed therethrough at least one passageway to receive the strap from the sock.Type: GrantFiled: October 6, 2011Date of Patent: February 4, 2014Inventor: Joseph Hollard
