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.

Various aspects of upper arm prosthetic system for a human subject having a body and a partial arm are described. According to one aspect, the system may comprise any one or more of a force amplification apparatus, a terminal unit apparatus, and/or an adjustable elbow apparatus. Each apparatus may be body-powered and/or comprise 3D printable structures. Related upper arm prosthetic apparatus, kits, methods, and systems also are described.

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 digit prosthesis assembly is described. Embodiments of the digit prosthesis assembly include, but are not limited to, an attachment assembly, a thumb assembly, one or more finger assemblies, a pinky finger assembly, a palm engagement assembly, and combinations thereof.

A transfemoral prosthetic level socket system for a user's lower limb comprising modular socket components fitted to the individual user's residual limb having a mounting point for an attachment, at least one compliant member attached to at least one stabilizing unit, and at least one second compliant member attached to at least one stabilizing unit wherein the first compliant member and the second compliant member work in cooperation with the stabilizing unit(s) to control bone position and support the limb within the interface.

A prosthetic arm apparatus comprising a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.

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 post-operative support apparatus for a patient's transfemoral residual limb, includes: a planar, stretchable, tensionable and flexible wrap panel sized to wrap around an outer circumference of a patient's transfemoral residual limb, where the wrap panel includes first fastener(s) for maintaining the wrap panel in place around the patient's residual limb; a planar, stretchable, tensionable and flexible hip-band sized to wrap around an outer circumference of a patient's hip or waist, where the hip-band includes second fastener(s) for maintaining the hip-band in place around the patient's hip or waist; and third fastener(s) releasably fastening the wrap panel to the hip-band.

A prosthesis socket having a proximal insertion opening and an inner circumference which at least partially surrounds a limb stump, at least one connection device for a prosthesis component, which is connectable to the prosthesis socket, at least one actuator operable to change the inner circumference of the prosthesis socket, and at least one sensor coupled to a control device, wherein the control device is connected to the actuator and activates or deactivates same, depending on the received sensor signals, and to a method for adjusting the inner circumference.

The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. In one embodiment, the assembly includes an eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A ring configured to receive a user's residual finger is disposed upon the articulation assembly, and may be adjusted to a target location based on a length of the residual finger. The articulation assembly is configured to utilize vertical movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-z plane, and the MCP pivot is configured to utilize lateral movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane. Other embodiments are also disclosed.
