Abstract:
Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.
Abstract:
A prosthetic foot comprises a resilient bottom member, a resilient top member, wherein the anterior top end is connected to the anterior bottom end of the resilient bottom member, and wherein the resilient top member is positioned over the resilient bottom member, and an elastomeric bumper member comprising a tapered surface configured to contact the resilient bottom member and attached to an underside of the posterior of the resilient top member. The prosthetic foot can further comprise a toe pad having a spacer coupled to, and creating space between, the bottom member and the top member, and an adhesive bonding one of the bottom member and one end of the top member, where the adhesive is commingled with the spacer between the first bottom end and the first top end.
Abstract:
Systems and methods for assistive devices for replacing or augmenting the limb of an individual, such devices comprising a joint and a powered system; the powered system having a first configuration in which the powered system rotates the joint by applying power to the joint, and a second configuration that allows for rotation of the joint without actuation of the powered system.
Abstract:
An articulating connection or joint for a limb support device having a first support member and a second support member pivotably couples together the first support member and the second support member. The articulating connection can include one or more first articulating connection member, or load-bearing pin, and one or more second articulating connection member, or bushing, disposed about the first and second support members. The load- bearing pin is coupled to one of the support members and the bushing is coupled to another of the support members. The bushing is configured to rotatingly receive the load-bearing pin and interacts with an actuation member configured to apply a force on the load-bearing pin to eccentrically align the load-bearing pin relative to the bushing so that the load-bearing pin continuously follows and contacts a bearing surface of the bushing during use of the limb support device, thereby inhibiting noise generation from the interaction of the bushing and load- bearing pin.

Überschreiten eines vorbestimmten Drucks in der ersten Kammer die erste Drossel schliesst, und eine zweite Drossel, die das Austreten des Fluids aus der zweiten Kammer drosselt, und eine zweite Einrichtung, die so ausgebildet ist, dass sie bei Erreichen bzw. Überschreiten eines vorbestimmten Drucks in der zweiten Kammer die zweite Drossel schliesst.
Abstract:
A prosthesis or orthosis (orthotic brace) comprises at least two parts (1, 2) connected to each other by means of an artificial joint (K), and a control device for the joint, to brake or lock the joint. The prosthesis or orthosis comprises a sensor (5) which detects the position in relation to a fixed line (L) of a part connected to the joint (K) and which is connected to a control device (4) arranged to influence the joint (K) on the basis of position data given by the sensor (5). The prosthesis or orthosis is a lower limb prosthesis, such as a thigh prosthesis or a hip ex-articulation prosthesis, or a lower limb orthosis. The sensor (5) is arranged to detect the position of the thigh part (1) in relation to a vertical line (L). The control device (4) is arranged to influence the movement resistance properties of the joint (K) on the basis of data given by the sensor (5). The sensor (5) is based on detecting the direction of earth's gravity.
Abstract:
The invention relates to a prosthesis comprising two prosthesis parts (1, 3) connected for mutual movement which are characterized by actuable means (21) for locking respectively releasing the prosthesis parts (1, 3) relative to each other. The parts (1, 3) are preferably connected for mutual movement by means of an artificial joint (2) comprising a first (17) and a second (18) joint part. The locking means consist for instance of a tiltable locking element (21) under spring bias, a part of which co-acts in the locked position with a recess (27) in one of the joint parts (17), whereby tilting of the locking element (21) is bounded, and which in the released position is substantially freely tiltable. The prosthesis can be further provided with means (16) for actively placing the locking element (21) out of the active reach of the limiting recess (27). One (1) of the two prosthesis parts (1, 3) connected for mutual movement is formed by means for fixing the prosthesis to the remaining part of an amputated extremity (5), such as a cup (6) for receiving the outer end of the remaining part, means (9, 10, 11, 12) for fixing the prosthesis part (1) to a higher located part of the remaining part of the amputated extremity (5) and means for connecting the cup (6) and the fixing means (8). The second prosthesis part (3) is formed for instance by a device for replacing at least a part of the amputated extremtiy (5) and is preferably provided with damping means (49).

Abstract:
A prosthetic knee (100) provides security and stability, particularly to low activity users, household and limited community ambulators, single and/or slow speed ambulators, and those with little voluntary control, while also balancing walking (dynamic) performance for low activity users. The prosthetic knee (100) includes a housing (2), parallel anterior links (4, 5), a posterior link (3), and a chassis (1). The geometry of the links and their relationship to one another (3, 4, 5) allow for low voluntary control, shortening of mid-swing, which reduces stumbling risk, and geometric stability in stance. The anterior links (4, 5) are particularly oriented, sized and located to provide for stability. The anterior links (4, 5) both extend above the posterior link (3) and substantially below the posterior link (3). The prosthetic knee includes a friction adjustment mechanism (6), a stability adjustment mechanism (110), and an adjustable extension assist mechanism (14).
