A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

A prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person is provided. The residual limb has particular dimensions and anatomical contours; the prosthetic socket has dimensions and contours that fit the dimensions and contours of the residual limb. The prosthetic socket may also fit in a manner that is biomechanically appropriate for the individual. The prosthetic socket may be an assembly from groups of components that include (a) struts arranged longitudinally with respect to the residual limb, (b) proximal brim members arranged proximally to the struts and connected thereto; and (c) distal socket members disposed at the distal base of the prosthetic socket. The socket components within these groups may be modular in that they can vary with respect to dimensions and/or contours, and yet have common connecting features that permit assembly of the components together to form the prosthetic socket.

A prosthetic foot includes a cap, a retaining element and a plurality of blades. Each of the plurality of blades includes a proximal portion coupled with the cap, a middle portion coupled with the retaining element and a distal portion extending outwardly from the retaining element.

An outer frame for a prosthetic limb is provided. The outer frame is formed from one or more parts and has a plurality of air flow openings.

Prosthetic devices, such as prosthetic hands (including, e.g., bionic prosthetic hands controlled by myoelectric signals and/or equipped with force sensors for feedback) can utilize a modular design to simplify assembly and repair. In some embodiments, low-cost additive manufacturing techniques are employed, e.g., to create prosthetic device parts with complex interior geometries and/or functionally integrated components.

Systems, devices and methods for detecting ground contact with a lower-limb POD. A sensor array for the POD on a first or second body may include two or more sensors in an array that each detect a distance to a respective target on the other of the first or second body. The first and second bodies may move relative to each other thereby changing an offset distance or distances between the two bodies which is detected by the sensors. In some embodiments, the sensors may include Hall Effect sensors that detect distances to respective magnets. Load data based on the detected distances may be generated for control of the POD, such as for stance phase control.

The invention relates to a closure device (V) comprising at least one first and second closure part (1, 2). In particular, a first connection element (12) of the first closure part (1) has at least one guide portion (121), and a second connection element (22) of the second closure part (2) has at least one closure portion (221), wherein—the guide portion (121) has a guide surface (1210) which is inclined relative to the connection axis (A), with which the closure portion (221) comes into contact when the second closure part (2) is placed on the first closure part (1), and which forces the second connection element (22) to rotate about the connection axis (A) relative to the first connection element (12) along a first rotational direction (D1) when the two closure parts (1, 2) further approach each other under the effect of at least two magnet elements (M1, M2; M3, M4) of the closure device (V), —the closure device (V) has an adjusting device (M3, M4; 24) by means of which a force is applied to the second connection element (22), which has now assumed an intermediate position, in a second rotational direction (D2) opposite the first rotational direction (D1) such that the second connection element (22) is automatically rotated out of the intermediate position into a closed position relative to the first connection element (12) along the second rotational direction (D2), and —in the closed position (a), the closure portion (221) at least partly engages behind the guide portion (121) in order to hold the connection elements (12, 22), and thus the closure parts (1, 2), against each other, and (b) the second connection element (22) can be rotated in the first rotational direction (D1) in order to release the two closure parts (1, 2) from each other in order to open the closure device (V).

A prosthetic socket includes a conical cup, an outer layer on the outer surface of the conical cup, and a reinforcement layer on the inner surface of the conical cup. The prosthetic socket is shapeable after being heated to a shaping temperature. The outer layer is less malleable than the conical cup at the shaping temperature but has a higher rigidity than the conical cup at the shaping temperature and has smoother outer surface than an outer surface of the conical cup. The reinforcement layer has a higher resistance against circumferential stress than the conical cup. A residual limb or a model of a residual limb can be inserted into the preformed prosthetic socket. The prosthetic socket is then heated to the shaping temperature and molded to conform to the contour of the residual limb or the model to form a prosthetic socket.

In embodiments, a shock absorber system for a prosthesis includes an outer housing having a bore and attachable to a prosthetic limb; an inner housing, attachable to a prosthetic socket, within the bore for axial and rotational movement relative to the outer housing; a first resilient element within the outer housing that resists axial movement of the inner housing into the bore and urges the inner housing back to an uncompressed configuration; and alternatively or in addition a second resilient element within the outer housing that resists rotational movement of the inner housing relative to the outer housing, wherein a torsional force urging relative rotation between the inner housing and the outer housing causes compression of the second resilient element such that the second resilient element resists the torsional force and urges the inner housing and outer housing back to an aligned configuration.

A prosthesis includes first and second prosthetic limb components and a fastening system for fastening the first and second prosthetic limb components. The first prosthetic limb component is provided with a first coupling member and the second prosthetic limb component is provided with a second coupling member. The first coupling member includes a cylindric member having an axis, with a wall generally parallel with said axis. The second coupling member includes a circular skirt element having an axis and having corresponding external dimensions to the cylindric member whereby to permit a sliding fit therewith in an unfastened state. The fastening system includes a resilient member having an axis and is operable to expand laterally, orthogonally with respect to the axis such that, in a coupling mode of operation, the lateral expansion operates to cause the skirt to be in a state of frictional engagement with the other coupling member.
