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

Publication number: 20230115195Abstract: An additive manufacturing system and method for making components having filaments formed by elastomeric materials. A liner includes the filaments formed by an elastomeric material and is adapted for a prosthetic device system. The filaments form an elastomeric lattice structure and solid layers or features and define a ventilated structure permitting a transfer of air and moisture from an interior volume of the liner to an exterior or ambient liner. The liner may incorporate an adhesive and a textile layer secured to the elastomeric lattice structure and further define recesses and other features for improving a liner.Type: ApplicationFiled: October 7, 2022Publication date: April 13, 2023Inventors: Rowan CAIN, Stefan Teitur HALLDORSSON, Ivar OLAFSSON, Sigurdur ASGEIRSSON, Andri ORRASON, Stefan Orn STEFANSSON, Halldor EINARSSON, Hafsteinn JONASSON

Publication number: 20230058917Abstract: A prosthetic attachment system and corresponding lock assembly are provided for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket, by combining vacuum suspension and mechanical suspension. An attachment pin extends from a distal end of the prosthetic liner. A connector assembly secures to a distal end of the prosthetic socket and is adapted for receiving and locking to the attachment pin. A lanyard assembly has a first end secured to the connector assembly and a second end extending outwardly from the distal end of the prosthetic socket and adapted to secure to an exterior surface of the prosthetic socket by an external securing system.Type: ApplicationFiled: August 18, 2022Publication date: February 23, 2023Inventors: Hafsteinn JONASSON, Sigurdur HANNESSON, Oskar Thor LARUSSON, Margret Sol RAGNARSDOTTIR, Halldor ALBERTSSON

Publication number: 20220304833Abstract: 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: ApplicationFiled: June 15, 2022Publication date: September 29, 2022Inventors: David SANDAHL, Dana Stewart MARLIN, Hafsteinn JONASSON

Publication number: 20220273467Abstract: A prosthetic system includes a prosthetic foot having an upper foot element with a concave-forward facing portion and foot portion extending forwardly therefrom. An intermediate foot element is disposed below the upper foot element and has a front portion coupled to the foot portion of the upper foot element. A lower foot element is disposed below the intermediate foot element. A pump system is coupled to the prosthetic foot and comprises a pump mechanism including 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. An arm member is connected to the pump mechanism and operatively coupled to the intermediate foot element. The arm member is arranged to move the pump mechanism toward at least the expanded configuration upon movement of the intermediate foot element relative to the upper foot element.Type: ApplicationFiled: May 18, 2022Publication date: September 1, 2022Inventors: Hafsteinn JONASSON, Dadi GRANZ, Marco STEINBERG, David SANDAHL
