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.

The walking canister system and method are for manufacturing a prosthetic socket. The system includes a rigid canister, a suspension bladder positioned within the rigid canister, and an outer chamber wicking material arranged in an outer chamber defined between the suspension bladder and the rigid canister. A foam insert includes a contoured exterior surface configured to transfer pressure through to an interior surface thereof to produce consistent surface contact with a residual limb, of a walking patient, having casting material thereon. An inner chamber wicking material is arranged in an inner chamber defined between the foam insert and the suspension bladder. An outer chamber vacuum port is in fluid communication with the outer chamber, and an inner chamber vacuum port is in fluid communication with the inner chamber. An outer chamber suspension sleeve is configured to extend from the residual limb and over the rigid canister.

A prosthetic cover (104) for a prosthetic support element (102) can include a substantially cylindrical hollow body (106) with a first end and a second end and sized to fit around a support element of a prosthesis. A first flexible end seal (108) and a second flexible end seal (110) can each attach with the substantially cylindrical hollow body at the first and second ends, respectively, and connect the hollow body with the support element of the prosthesis by deforming about the support element when the prosthetic cover is installed around the support element.

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.

A prosthetic liner includes a flexible elongate, generally conical body portion formed from an elastomeric material. The body portion defines an inner surface, an outer surface forming a liner profile between a distal end and a proximal end, and an axis extending between the distal and proximal ends. At least one seal element extends circumferentially about the axis and protrudes radially outward a distance from the liner profile. The at least one seal element has a seal height defined between the liner profile and a radially outward end of the at least one seal element. The seal height varies circumferentially about the axis between a first seal height and a second seal height.

A prosthesis liner provided for fitting over a stump of a limb. The prosthesis liner includes a main body having an inner face directed towards the skin of the stump, and an outer face directed away from the stump. The prosthesis liner also includes a proximal access opening and a side wall, which extends from the access opening as far as a closed distal end portion of the liner. At least one sealing lip is arranged on the outer face of the main body and protrudes radially outwards from the main body.

A training device for stimulating nerve cell ends in a training manner, includes a housing having at least one first housing portion and a plurality of stimulators for stimulating physionomie-typical nerve area portions. A plurality of stimulators are arranged systematically at least on the first housing portion of the housing so that the plurality of stimulators in the training state each act on nerve cell ends with which they are associated. Also disclose are a method for operating the training device, the use of the training device as a modular stimulation device for stimulating nerve cell ends, a prosthesis, a method for producing a prosthesis and the use of a training device for stimulating nerve cell ends in a prosthesis.

A prosthesis suspension system comprises a socket for receiving a residual limb, a locking liner having a locking pin for attaching the liner to the socket and a sealing cap disposed between the locking line and the socket. The system further comprises a gap between a skirt of the sealing cap and an interior wall of the socket in which the skirt of the sealing cap is able to move between first and second positions.

A method for making a mould of an amputation stump, in which the amputation stump is inserted into a liner of a moulding aid, the liner having a longitudinal direction and a circumference, and the liner having an expansion coupling such that when the liner is extended in the longitudinal direction, this necessarily results in a reduction of the circumference.

Embodiments herein relate to socket liners for prosthetic systems and prosthetic systems including the same. In an embodiment, a socket liner for a prosthetic system is included having a polymeric wall member defining an interior volume. The polymeric wall member having an inner surface bordering the interior volume and an outer surface. The polymeric wall member can include an anterior side, a posterior side, a first lateral side and a second lateral side the second lateral side opposite the first lateral side. A plurality of horizontal ridges can be disposed on the inner surface of the polymeric wall member on the first lateral side and the second lateral side. A plurality of vertical channels can be disposed on the inner surface of the polymeric wall member on the anterior side and the posterior side. Other embodiments are also included herein.
