Patent number: 11833104Abstract: Various features for improving the performance of crutches are provided. A crutch can flex at one or more locations or include composite material to provide energy storage and return to the user during ambulation. In some aspects, a crutch is provided that can propel the user forward during ambulation. The crutch can be hollow at one or more locations to allow for increased flexibility and narrower at one or more locations to enhance springiness of the crutch.Type: GrantFiled: November 2, 2020Date of Patent: December 5, 2023Assignee: Össur Iceland ehfInventors: Arinbjörn Viggo Clausen, Aron Kristbjorn Albertsson, Gudfinna Halldorsdottir

Publication number: 20220125607Abstract: A vacuum suspension system includes a foot cover having a heel portion and a pump system located in the heel portion. The pump system includes upper and lower sections arranged to move in an axial direction relative to one another and a pump mechanism operatively connected to and positioned between the upper and lower sections. When the heel portion is loaded in stance the pump mechanism moves from an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, to an expanded configuration in which the volume of the fluid chamber is increased.Type: ApplicationFiled: January 11, 2022Publication date: April 28, 2022Inventors: Atli Orn SVERRISSON, Larus GUNNSTEINSSON, Gudfinna HALLDORSDOTTIR, Hafsteinn JONASSON, Dadi GRANZ, Dana Stewart MARLIN

Publication number: 20190110909Abstract: A method of regulating pressure inside a prosthetic socket includes measuring pressure inside of a prosthetic socket using one or more sensors operatively coupled to a pump system to obtain pressure information associated with an inside of the prosthetic socket. The pump system has a pump mechanism in fluid communication with the inside of the prosthetic socket. The method involves actuating the pump mechanism without human intervention to regulate vacuum inside of the prosthetic socket based on the pressure information.Type: ApplicationFiled: December 12, 2018Publication date: April 18, 2019Inventors: Atli Orn SVERRISSON, Gudfinna HALLDORSDOTTIR

Patent number: 10179055Abstract: A vacuum suspension system includes a prosthetic socket adapted to receive a residual limb. A pump system includes a pump mechanism in fluid communication with the prosthetic socket, and at least one sensor associated with the prosthetic socket and/or the pump mechanism. A control system is operably connected to the pump mechanism and the least one sensor. The control system is arranged to receive and process data from the at least one sensor and to actuate the pump mechanism based on the received data from the at least one sensor.Type: GrantFiled: May 24, 2016Date of Patent: January 15, 2019Assignee: OSSUR ICELAND EHFInventors: Atli Orn Sverrisson, Gudfinna Halldorsdottir

Patent number: 9943421Abstract: A vacuum suspension system includes a pump system arranged to be in fluid communication with a prosthetic socket. The pump system includes a pump mechanism having a housing and a membrane situated on the housing such that a fluid chamber is defined between the membrane and the housing. The pump mechanism is movable between an original configuration in which the volume of the fluid chamber is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.Type: GrantFiled: May 23, 2016Date of Patent: April 17, 2018Assignee: OSSUR ICELAND EHFInventors: Atli Orn Sverrisson, Larus Gunnsteinsson, Gudfinna Halldorsdottir, Hafsteinn Jonasson, Dadi Granz, Dana Stewart Marlin
