A dynamic support system includes a control system for controlling inflation and deflation of at least one actuator having an inlet connectable to the a control unit of the dynamic support system. The control unit may be in communication with a sensor and may control inflation and deflation of the at least one actuator in response to information provided by the sensor.

Systems and methods for modular adjustable prosthetic volume compensation are disclosed herein. In one embodiment, a system for adjusting fit of a prosthetic device includes: a pump having a bleed actuator, a plunger and a pressure bulb. The system also includes a bladder fluidically coupled to the pump. The bladder lines a posterior section of an interior of a prosthetic device. A volume of the bladder is changeable by a pumping action of the pump. The volume of the bladder at least partially determines a space available inside the prosthetic device. The bleed actuator is configured to decrease a volume of the bladder. The plunger in operation squeezes the pressure bulb of the pump.

A dynamic support apparatus having a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic interface is capable of changing its geometry and is disposed on the top surface of the frame. The control system is operably connected to the dynamic interface and controls the changing geometry of the dynamic interface. There is also a temperature control mechanism disposed on the top surface of the frame for maintaining a comfortable temperature and moisture environment between the apparatus and the user's body.

A prosthetic liner for insertion within a socket of a prosthetic limb is provided. The prosthetic liner comprises a body having inflatable bladders and pressure sensors disposed thereon, an electronic circuit, one or more actuators, and a processor. The body receives a residual limb on an interior surface and contacts the socket on an exterior surface. The processor receives a digital pressure signal indicative of a detected pressure from each pressure sensor via the electronic circuit and selectively activates the actuators to adjust a pressure in one or more of the inflatable bladders based on the digital pressure signals and the region of the body corresponding to each digital pressure signal.

Systems and methods are described herein for a prosthetic device that includes a premade outer shell socket with an inner surface contour. A prosthetic insert socket is manufactured via a manufacturing process, such as three-dimensional printing, to have an outer contour that corresponds to the inner surface contour of the premade outer shell socket. The prosthetic insert socket is manufactured to have an inner contour that corresponds to a residual limb surface contour of a patient.

A control unit system. The system includes a control unit which includes a control unit charging interface, at least one magnet located proximate to the control unit charging interface, at least one actuator, a detachable manifold including at least one magnet, fluidly coupled to the at least one actuator, a pump connected to the at least one actuator for causing actuation thereof, and a control system for controlling the pump, wherein the control system controls the pump to actuate the at least one actuator at least in response to a signal received by the control system. The system also includes a recharging device configured to receive the control unit, the recharging device including a reed switch, wherein when the magnet in the control unit is located proximate to the reed switch, the switch is activated.

Apparatus is provided to cushion between a prosthetic socket and an amputee's residual limb. A plurality of putty-filled packets are assembled into a liner that, when assembled, provides a generally smooth contact surface toward the residual limb. At least one of the packets has a fluid bladder positioned between the putty material and the socket, and the fluid volume in the bladder can be adjusted to affect the fit of the assembly on the residual limb. Methods of fabrication, fitting, and use of such prosthetic devices are disclosed.

There is provided an apparatus comprising: 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 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; and a control circuit for controlling the fluid source; wherein 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; and wherein the control circuit is configured to implement the control operation by controlling the supply of fluid to or from the hollow chamber.

The invention provides for an improved disarticulated compression socket configured to secure a residual limb. The disarticulated compression socket may include a rigid socket frame, and preferably a 3-D printed socket having one or more surface channels that may secure a compression cord optionally positioned within a cord cylinder. Such compression cord may be responsive to a compression actuator and one or more disarticulated compression inserts such that activation of the compression actuator causes the retraction of the compression cord initiating the coordinated inward compression of each of said disarticulated compression inserts securing the residual limb within said socket frame.
