An intracorporeal portion of a percutaneous device for a joint disarticulation prosthesis or joint replacement prosthesis, the intracorporeal portion having an extracorporeal portion or having means for rigidly coupling directly to an extracorporeal portion, the extracorporeal portion being for location exterior to the skin, the intracorporeal portion having an articulating component for articulating with an articulating surface, wherein the articulating component is intracorporeal when installed in a human or animal subject.

The present disclosure is directed to prosthetic limb sockets that couple prosthetic limbs to residual limbs. The sockets include a conical cup sized to engage and couple to the residual limb, and a base to secure the socket to the prosthetic limb. The sockets are direct heat-formable onto the residual limb, such that they can be heated and formed as they are secured to the residual limb.

The present invention relates to a an attachment device for attaching a prosthesis to a bone, comprising: a base plate having an extension in an xy-plane; a first holder for holding a first abutment; a second holder for holding a second abutment; a locking plate attached to the base plate to restrict movement of the holders in a z-direction away from the base plate. The locking plate is configured to allow rotation of the first and second holder around a z-axis perpendicular to the xy-plane. The locking plate and the base plate is configured to allow movement of the first holder along the x-direction and to prevent movement the y-direction and to prevent movement of the second holder in the x- and y-direction. At least one flexible member is arranged between each of the first and second holders and the base plate, the flexible member being flexible in the z-direction to allow movement of the first and second holder in the z-direction and to allow the first and second holder to tilt with respect to the xy-plane.

A system and method for improving limb function through the use of percutaneous mechanical and neural interfaces. The system generally uses a hollow long bone axial rod that is inserted into the long bone medullary cavity. A transfer rod with a central channel is mounted to the long bone axial rod. An exterior body attachment is connected to the transfer rod and attachment rings attach muscle groups, fascia layers and dermal layers to the transfer rod. Additionally, the system is configured to collect and transmit nerve signaling data to an external processor and additionally configured to transmit data from the external processor to the plurality of nerves.

A surgical implant for supporting a prosthetic device at a distal end of an amputated limb, including:

a cup having a base and surrounding side wall for defining therein a volume for accommodating a terminal end of a bone of the amputated limb;

a central intramedullary stem extending from the cup base for insertion into a medullary cavity of the bone;

a plurality of extramedullary struts extending from the side wall generally parallel to the central intramedullary stem and locatable in contact with or in a closely adjacent relation with an outer surface of the bone; and

an attachment member extending from an outer face of the cup base.

A prosthetic coupling device including a first coupling part and a second coupling part is provided. The first coupling part has a first end and a second end and the second coupling part has a first end and a second end. The first end of the first coupling part is connectable to the first end of the second coupling part, and the second end of the first coupling part is connectable to a prosthetic adapter element of a first prosthetic member. The second end of the second coupling part is connectable to a prosthetic adapter element a second prosthetic member. The prosthetic coupling device further includes first and second manually operable locking arrangements, which are separately operable and each locking arrangement has a locked configuration and a release configuration. Furthermore, the prosthetic coupling device is transferable from a connected state to a disconnected state only when both of the locking arrangements are in the release configuration. A use of a prosthetic coupling device is also provided. Further, a prosthetic assembly is also provided. A coupling part for use in the coupling device is also provided. method for connecting and disconnecting a first prosthetic member to a second prosthetic member is also provided.

A magnetic and electrical interface that may be used with an assistive device. The interface comprises a proximal connector and a distal connector. The proximal connector may be attached to a liner for a residual limb and the distal connector may be attached to a hard socket or other aspect of an assistive device. Other aspects of and uses for the connector interface are also disclosed.

An abutment system for operatively coupling an implant stem to an exo-prosthesis. The abutment system includes a plurality of interlocking sleeve elements that are operatively coupled to an implant stem positioned within a prepared site of a selected bone. The interlocking sleeve elements of the abutment system are selectively removable and replaceable.

An implant assembly for a long bone having a longitudinal axis. The implant assembly has a stem that is received in a surgically prepared medullary canal of the long bone. The stem defines at least one transverse through-opening that extends through the stem from a first portion of the outer surface of the stem to an opposed second portion of the outer surface of the stem. Each transverse through-opening has a central axis that is substantially perpendicular to the longitudinal axis of the stem. Each transverse through-opening receives a fastener and has a longitudinal dimension, measured relative to the longitudinal axis of the stem, that is sufficient to permit axial movement, relative to the longitudinal axis of the stem, of the stem relative to each fastener.
