Patent number: 11696842Abstract: A vacuum assisted suspension system includes a prosthetic foot and a pump mechanism connected to the foot and fluidly couplable to a prosthetic socket. The pump mechanism includes an elongate pivoting member rotatable relative to the prosthetic foot about a joint and including a distal recess. A piston is connected to the foot and is movably received in the recess. A fluid chamber is defined between the piston and the interior of the recess. When no weight is placed on the foot a volume of the fluid chamber is zero or near-zero and when weight of a user is placed on the prosthetic foot the pivoting member rotates away from the piston and expands the volume of the fluid chamber to draw fluid into the fluid chamber from the prosthetic socket.Type: GrantFiled: April 13, 2020Date of Patent: July 11, 2023Assignee: OSSUR HFInventors: Grimur Jonsson, Bjarni Gunnarsson, Olafur Freyr Halldorsson, David Sandahl

Publication number: 20230087706Abstract: A prosthetic system includes a prosthetic foot defining an upper surface and having a flexible configuration and a pump system attached to the prosthetic foot. The pump system includes a pump mechanism defining a fluid chamber having variable configuration and an actuating part. The actuating part is arranged to selectively engage with and separate a distance from the upper surface of the foot plate to move the pump mechanism between a first position in which a volume of the fluid chamber is zero or near-zero and a second position in which the volume of the fluid chamber is expanded relative to the first position. The volume of the fluid chamber increases when the actuating part moves away from the upper surface of the foot plate.Type: ApplicationFiled: November 23, 2022Publication date: March 23, 2023Inventors: Olafur Freyr HALLDORSSON, David SANDAHL, Bjarni GUNNARSSON, Egill Sveinbjorn EGILSSON

Patent number: 11058561Abstract: A prosthetic system includes a prosthetic valve having a valve body with a shaft defining a flow channel fluidly connectable to an interior of a socket. One or more ports in the valve body are in fluid communication with the flow channel and a membrane is positioned in the valve body. A release button associated with the membrane controls allow air flow into the socket via the one or more ports while air can flow out of the socket via the one or more ports independent of operation of the release button. A one-way valve is connected to the valve assembly that selectively permit air flow out of the socket. A valve insert is mountable on the socket and arranged to couple the valve body to the socket. The valve insert defines an opening configured to allow the shaft to extend through the valve insert and into the socket.Type: GrantFiled: April 10, 2018Date of Patent: July 13, 2021Assignee: OSSUR HFInventors: Olafur Freyr Halldorsson, David Sandahl, Bjarni Gunnarsson, Egill Sveinbjorn Egilsson

Patent number: 10376391Abstract: A prosthetic device includes first and second regions divided by a longitudinal line extending between the first and second ends of the device. The device has a continuously knit elasticized fabric layer including a first set of yarns located about a circumference of the device through the first and second regions. The fabric layer has different knit structures in the first and second regions to obtain different elasticity while sharing the first set of yarns so that the first region has a first elasticity, and the second region has a second elasticity greater than the elasticity of the first region. An elastomeric layer secures an interior surface of the fabric layer.Type: GrantFiled: April 19, 2018Date of Patent: August 13, 2019Assignee: Ossur HFInventors: Olafur Freyr Halldorsson, Knud Fjeldsted Rasmussen
