A transtibial prosthetic socket frame may include a distal base assembly having a base plate, a carriage configured to support a socket suspension arrangement, and a distal prosthetic component connector. The distal base assembly supports a set of struts that includes two anterior struts and a single posterior strut. The set of struts and distal base assembly collectively define a prosthetic socket cavity having a central longitudinal axis and a residual limb hosting volume. The distal prosthetic component connector has a connecting adapter that is rotatable with respect to the prosthetic socket, and moveable with respect to the base plate between being aligned with the prosthetic socket's central longitudinal axis and a position offset therefrom.

Various systems and methods for removing perspiration from the interior of a donned polymeric prosthetic liner are disclosed.

An apparatus includes a flexible sheet having a hollow chamber disposed within a thickness of the flexible sheet at a localised region of the flexible sheet, and an opening for transfer of a fluid between an exterior of the flexible sheet and the hollow chamber. A fluid source is configured to supply a fluid to the hollow chamber via the opening to cause an increase in at least one of the surface area or the volume of the flexible sheet at the localised region. A control circuit controls the fluid source. The control circuit is configured to determine a control operation by identifying a category of movement of a user and/or predicting a required change in pressure in the hollow chamber. The control circuit is further configured to implement the control operation by controlling the supply of fluid to or from the hollow chamber.

According to embodiments of the invention a novel prosthetic socket may include one or more inflatable pressure bladders disposed within the socket which may be controlled to be set at a desired pressured by the patient, and then automatically monitored and controlled to maintain the set pressure. The user may further incrementally increase or decrease the pressure as needed for different activities. A control system may comprise an external control device, such as a cell phone/tablet running a proprietary control and monitoring application, and may further include a back-end server which stores patient data, operating values and long term monitoring data.

A sensory cushioning system, method, and associated apparatus and airbag, an internal electronic assembly, an external electronic assembly, and an interconnect. The airbag forms an interior volume and a pocket, wherein the interior volume is substantially airtight. The internal electronic assembly is positioned within the pocket. The external electronic assembly is positioned exterior to the airbag. The interconnect electrically couples the internal electronic assembly to the external electronic assembly.

A limb prosthesis including a socket having an inner cavity configured for disposal therein of a limb stump of a user, and a mechanism for changing an inner diameter of the inner cavity by a remote control, where the inner diameter includes a lining disposed within the cavity, having between fifteen and sixty of only longitudinal inflatable cells where each of the cells is situated immediately adjacent to two other of the cells such that no intervening element aside from a shared border is provided between two such immediately adjacent cells, thereby diminishing blood flow blockage in the limb stump, and a pump assembly, for inflating and deflating the inflatable lining to a desired air pressure set by a user or by a controller, the remote control being in data communication with the pump assembly, for instructing the pump assembly to inflate or deflate the lining to the desired air pressure.
