Publication number: 20160199202Abstract: A prosthetic system includes a prosthetic foot with a foot member defining a first end portion, a second end portion, and an intermediate portion defining a curvature and extending between the first and second end portions. A pump mechanism is coupled to the foot member. The pump mechanism includes a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. A movable member includes a first portion coupled to the membrane and a second portion arranged to slidably engage the foot member. Relative movement between the first and second end portions moves the first portion of the movable member relative to the housing and slides the second portion along a length of the foot member to shift the pump mechanism between the original and expanded configurations.Type: ApplicationFiled: January 5, 2016Publication date: July 14, 2016Inventors: Hafsteinn JONASSON, Hallgrimur Skuli HAFSTEINSSON, Egill Sveinbjorn EGILSSON, Dana Stewart MARLIN, Marco STEINBERG

Publication number: 20160106557Abstract: A suspension liner is adapted to provide an interface between a residual limb and a prosthetic socket. The suspension liner defines an interior surface and an exterior surface forming a liner profile between a closed distal end and an open proximal end. The suspension liner defines a liner body portion formed from an elastomeric material and at least one seal protruding circumferentially about and radially outward a distance from the liner profile, which is defined at areas outside the at least one seal. The at least one seal defines a sealing surface arranged to deflect toward the liner profile and take up a higher pressure when donned on a residual limb and engaged with an interior wall of the prosthetic socket.Type: ApplicationFiled: December 22, 2015Publication date: April 21, 2016Inventors: Egill Sveinbjorn EGILSSON, Sigurdur ASGEIRSSON

Patent number: 9295567Abstract: 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: GrantFiled: May 19, 2014Date of Patent: March 29, 2016Assignee: OSSUR hfInventors: Egill Sveinbjorn Egilsson, Sigurdur Asgeirsson

Publication number: 20150238331Abstract: A prosthetic system includes a pump mechanism operatively connectable to a prosthetic foot. The pump mechanism has a housing defining first and second ports, a membrane having an outer edge portion secured to the housing, and a fluid chamber with a volume defined between the housing and a first side of the membrane. The fluid chamber is in fluid communication with the first and second ports. A connector is attached to a second side of the membrane opposite the first side. The connector operatively connects the membrane to the prosthetic foot such that when no weight is placed on the prosthetic foot the volume of the fluid chamber is zero or near-zero and when weight of a user is placed on the prosthetic foot the membrane deforms to expand the volume of the fluid chamber.Type: ApplicationFiled: April 30, 2015Publication date: August 27, 2015Inventors: Olafur Freyr HALLDORSSON, David SANDAHL, Bjarni GUNNARSSON, Egill Sveinbjorn EGILSSON

Patent number: 9072617Abstract: 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: GrantFiled: April 30, 2013Date of Patent: July 7, 2015Assignee: OSSUR HFInventors: Olafur Freyr Halldorsson, David Sandahl, Bjarni Gunnarsson, Egill Sveinbjorn Egilsson
