Publication number: 20070255194Abstract: A method for producing a wound dressing wherein a curable silicone mixture is extruded onto a generally planar molding surface. The silicone mixture defines a first surface adjacent the planar surface and a second surface opposite the first surface. The molding surface is heated at a curing temperature sufficient to cause the silicone mixture to cross-link. The silicone mixture is uniformly spread over the molding surface such that the silicone mixture has a generally uniform thickness and the second surface is substantially planar. The second surface of the silicone mixture is laminated to an absorbent material after the silicone mixture has started to cross-link and transform to a gel due to exposure to the heated molding surface.Type: ApplicationFiled: June 29, 2007Publication date: November 1, 2007Inventors: Palmar Gudnason, Thordur Elefsen, Gudni Ingimarsson, Sigurdur Asgeirsson

Publication number: 20070156252Abstract: Abstract of the Disclosure A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface.Type: ApplicationFiled: September 1, 2005Publication date: July 5, 2007Applicant: Ossur hfInventors: Helgi Jonsson, Arinbjorn Clausen, Gudni Ingimarsson, Christophe Lecomte

Patent number: 7217060Abstract: A locking mechanism includes a centering axle having an engaging member defined at one end thereof, a sleeve encompassing a portion of the centering axle, and a clutch device that securely receives the sleeve and permits rotation of the centering axle and the sleeve in only one direction. The centering axle defines a plurality of equally spaced grooves, and the sleeve defines a plurality of equally spaced grooves corresponding to the grooves of the centering axle in an opposed manner. Each pair of opposed grooves of the centering axle and sleeve define a narrow passageway that accommodates a ball bearing that is slidable along the longitudinal axis of the centering axle and between the sleeve and centering axle. The ball bearing in each passageway permits longitudinal movement of the centering axle relative to the sleeve and prohibits rotation of the centering axle relative to the sleeve.Type: GrantFiled: April 30, 2004Date of Patent: May 15, 2007Assignee: Ossur HFInventor: Gudni Ingimarsson

Patent number: 6589289Abstract: A prosthetic socket includes a recess at its distal end for receiving a prosthetic socket component such as a pin interlock device and a threaded opening providing access to the recess from the inside of the socket. A threaded retainer may be threadedly fastened to the threads of the opening for removably retaining the prosthetic socket component within the recess.Type: GrantFiled: October 4, 2001Date of Patent: July 8, 2003Assignee: Ossur hfInventor: Gudni Ingimarsson

Patent number: 6416703Abstract: A definitive socket for residual limb prosthetic use is formed in a single molding step by compressive pressure casting or molding a pre-formed, moldable, hardenable socket material over a residual limb and curing the socket material to a load-bearing hardened condition while it is maintained under peripheral compressive pressure against the residual limb and while the residual limb is tensioned in a distal direction during the casting process. The combination of pressure casting the socket material and applying tension to the residual limb in a distal direction while the socket material is curing results in forming a definitive socket that fits well to the residual limb after curing without substantial rectification. Pressure relief formations, socket coverings, and a prosthesis coupler may be compression molded simultaneously with the socket.Type: GrantFiled: September 21, 1999Date of Patent: July 9, 2002Assignee: Ossur hfInventors: Össur Kristinsson, Tryggvi Sveinbjörnsson, Hilmar Br.
