An adjustable prosthetic socket includes proximal and distal ends and an axis extending between the proximal and distal ends. A distal base is adapted to support a distal portion of a residual limb and is located at the distal end of the socket. First and second spines extend upward from the distal base that define at least part of a circumference of the socket about the axis. A proximal support is connected to the second spine and arranged to distribute pressure from the second spine over a portion of the residual limb. A tensioning system is operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket. The tensioning system includes a dial tensioner connected to the first spine.

A prosthetic connector system for use with a prosthetic socket having a distal end includes a plate defining a plurality of holes and attachable to the distal end of the prosthetic socket. A component is removably attachable to the plate via the plurality of holes and arranged to connect a prosthesis to the prosthetic socket. The plate defines an outer periphery having an asymmetrical configuration contoured to substantially correspond to at least a portion of the component when the component is attached to the plate via at least some of the holes.

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.

An adjustable prosthesis system for a residual limb includes: an adjustable outer shell surrounding the residual limb having a plurality of overlapping flaps, a top opening along a top edge extending around the outer shell, a bottom having a bottom edge opposite the top edge and extending around the bottom, a first side, and a second side having an adjustable width, and a plurality of adjustable overlapping side ends, some of which overlap and some do not, extending from the top edge to the bottom edge; a base adjacent the bottom of the outer shell and connected to it; and a closure component attached to the outer shell to compress the residual limb. Tightening the closure component applies a pulling force to at least one of the first side and the second side, thereby causing a reduction in width of a discontinuity and increased overlap of the side ends.

A prosthetic apparatus and system for a trans-tibial amputee consisting of a post-operative interface socket that can be adjusted to accommodate the size of an amputated limb and changes in size of the limb. The prosthetic apparatus includes a lower socket into which the post-operative socket can be inserted, the lower socket being adjustable for changes in size of the post-operative interface socket. The post-operative socket also has a removable upper back shell that immobilizes movement of the knee during an initial recovery phase but can be removed to allow the knee of the amputee to flex.

A method of forming a stump socket is disclosed. The method includes obtaining a stump casting, obtaining a socket adaptor, positioning the socket adaptor on a distal end of the stump casting, and applying a binder material to encapsulate the socket adaptor. A socket adaptor may have a main body and multiple flanges. Each of the flanges may have a proximal end and a distal end. The proximal end may pivotably connect to the main body. Accordingly, pivoting of the flanges with respect to the main body may enable the socket adaptor to better and more easily conform to the stump casting.

A liner for a prosthesis, wherein the liner is made of a liner material and comprises a proximal opening for accommodating an amputation stump, a distal end, a longitudinal direction, which extends from the proximal opening to the distal end, and an auxetic material The auxetic material is a two-dimensional-auxetic material, which is arranged in such a way that an extension of the liner in the longitudinal direction leads to an expansion of a diameter of the liner.

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.

A prosthetic socket, comprising a base for distal connection means for attaching a prosthesis component to the prosthetic socket and comprising at least one side wall, which extends from the base in the proximal direction and at least partially extends around a stump to be held in the prosthetic socket, and at least one support for fastening the side wall to the base being arranged on the base.
