A method of placing a prosthetic system over a residual limb, said method comprising the steps of: providing the prosthetic system; and placing an outer shell of the prosthetic system on the residual limb having an above-knee amputation, the outer shell at least partially surrounds the residual limb, an outer side and an inner side of the outer shell on opposite sides of the residual limb, an upper edge of the outer side above a greater trochanter, the inner side below a lowest edge of an ischium without being directly below the lowest edge of the ischium.

Modular arm prosthesis, for amputations higher than the level of the forearm. With the feature of being modular, which gives us an advantage that reduces the repair time by replacing the module quickly. The Socket-stump module which can be adjusted to several stumps thanks to its pneumatic system for grip, decreases the level of customization of each prosthesis thus reducing the manufacturing time and cost of production of each prosthesis, as well as its easy control by means of myoelectric sensors.

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.

In one aspect, novel robust electroactive polymers (EAPs) is described, which contract and expand at low voltages to provide for a shape-morphing system, e.g., a prosthetic liner, and potentially entire prosthetic socket, to contract and expand in strategic areas as needed to maintain a comfortable and good fit throughout the day. In some embodiments, as the residual limb changes, these novel robust EAPs can change dynamically as needed to maintain a comfortable, snug fit of the prosthetic liner or socket with the hard shell of the prosthetic socket device. In some embodiments, the EAPs used in prosthetic liners or sockets can also be used to detect pressure as the device is being used, and automatically adjust to maintain fit through a control unit, so that the patient does not even have to stop and adjust his or her device as he or she goes about an active day.

A lower limb prosthetic device for use when bathing and showering includes a first shell. A rod is coupled to and extends substantially perpendicularly from an upper face of the first shell. A second shell, which has a top that is open, is coupled to and extends from the rod distal from the first shell. The second shell is substantially complementary to and configured to insert a stump of an amputated leg. A plurality of bladders, which is selectively inflatable, is coupled to an inner surface of the second shell. The bladders are configured to be inflated to couple the second shell to the stump. A plurality of first holes and a plurality of second holes are positioned through the first shell and the second shell, respectively. The first holes and the second holes are configured to drain water from the first shell and the second shell, respectively.

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.

An orthopedic or prosthetic support including at least three layers that allows for aeration and cushioning of the enclosed area is described herein. The orthopedic or prosthetic support includes an inner cushioning layer which is compressed against the skin in use. An intermediate scaffolding layer is situated substantially parallel to the inner cushioning layer and is maintained in spaced apart relationship with the inner cushioning layer by spacer members. An exterior layer overlays the intermediate scaffolding layer and may be either a flexible breathable fabric such as velvet or a thermoplastic with a plurality of perforations. The inner cushioning layer and the intermediate scaffolding layer include a plurality of perforations providing air pathways through the two layers. The grid-like arrangement of spacer members also define air passages between the inner and intermediate layers which further enhance circulation of exterior air to the skin covered by the orthopedic or prosthetic support.

A system for joining a limb liner to a prosthesis. The prosthesis has a socket that is joined to the remainder of the prosthesis using a hub assembly. The hub assembly includes a first hub and a second hub. The first hub is disposed within the interior of the socket. The second hub is disposed outside the interior of the socket. An air conduit extends through the hub assembly that enables air to be drawn into the socket and/or vented from the socket. An inflatable interface is disposed within the socket. The inflatable interface receives air through the air conduit in the hub assembly. The inflatable interface is capable of filling any gaps that may exist between a limb liner being worn by an amputee and the socket.

A disarticulated compression socket configured to secure a residual limb. The disarticulated compression socket may include a rigid socket frame having one or more compression apertures each having one or more disarticulated compression inserts. Each disarticulated compression insert may be coupled with and/or responsive to a compression band configured to compress the disarticulated compression inserts and thereby secure a residual limb within the rigid socket frame.
