Publication number: 20240350286Abstract: An adjustable socket system includes a distal portion and proximal portion. An axis extends between the distal and proximal portions. A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to differentially tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb via a single input.Type: ApplicationFiled: July 2, 2024Publication date: October 24, 2024Inventors: Andrew BACHE, Egill Sveinbjorn EGILSSON, Linda Ros BIRGISDOTTIR, Dana Stewart MARLIN

Patent number: 12004972Abstract: A prosthetic system includes first and second parts rotatable relative to one another about a joint. The first and second parts are adapted to form at least part of a weight bearing connection between a prosthetic foot and a socket. A pump system includes a pump mechanism operatively connected to the first and second parts. Rotation of the first part and/or the second part about the joint moves the pump mechanism between an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.Type: GrantFiled: June 15, 2022Date of Patent: June 11, 2024Assignee: OSSUR ICELAND EHFInventors: David Sandahl, Dana Stewart Marlin, Hafsteinn Jonasson

Publication number: 20230270573Abstract: 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: May 5, 2023Publication date: August 31, 2023Inventors: Hafsteinn JONASSON, Hallgrimur Skuli HAFSTEINSSON, Egill Sveinbjorn EGILSSON, Dana Stewart MARLIN, Marco STEINBERG

Patent number: 11413167Abstract: A prosthetic joint can include a first attachment member and a second attachment member coupled to the first attachment member. The second attachment member can include a cylindrical chamber. The prosthetic joint can include a fixation system disposed within the cylindrical chamber comprising at least one cam. The prosthetic joint can have an unlocked configuration, wherein in the unlocked configuration the first attachment member and the second attachment member can rotate relative to each other. The prosthetic joint can have a locked configuration, wherein in the locked configuration the first attachment member is substantially prevented from rotating relative to the second attachment member.Type: GrantFiled: July 30, 2019Date of Patent: August 16, 2022Assignee: Össur Iceland EhfInventors: Dana Stewart Marlin, David Sandahl
