A system and method are provided for electronically capturing a subject's anatomy comprising an electronic device with a camera, display screen, and end-user software program to interface with the user. The software program tracks a target placed in view area, and gives visual feedback to the user based on target tracking. The software program includes criteria represented visually, via audio feedback, or haptic feedback, to the user indicating how to position the camera relative to the anatomy. The end-user software program may have means to automatically capture anatomy on the electronic device based on the criteria being met. The end-user software program may include an auto-zoom, target distortion correction features, and/or other features such as the use of a virtual markers.

A prosthetic foot comprises a hollow triangular lightweight top section that is an integral part of a first leafspring that originates from a top portion to the toe of the prosthetic foot. The prosthetic foot further comprises a second leaf spring. The second leaf spring originates from the heel to the toe.

A prosthetic device includes a polymer lattice structure. The lattice structure includes a first surface arranged to face toward a residual limb, a second surface arranged to face away from the residual limb, a thickness between the first and second surfaces, and a variable lattice density across the thickness.

Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

A prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an outer textile with variable stretch characteristics due to the knit construction and stitching and an interior gel layer. The distal region of the liner textile has less stretch than does the intermediate region or proximal region and is stitched together to form a unitary liner. The liner advantageously minimizes a condition referred to as “pistoning” wherein the distal most portion of the residual limb ascends and descends in the lower portion of the socket creating an unhealthy condition for the residual limb.

A liner system for reducing motion of a skeletal structure within a limb is described. The liner system includes a liner adapted to be worn over the limb and one or more shims adapted to be pre-placed along a length of the skeletal structure of the limb prior to donning the liner on the limb. The one or more shims each have a durometer, a radial thickness, a width, and a longitudinal dimension configured to compress a target area of soft tissue against the skeletal structure such that motion of the skeletal structure towards a wall of the shim is reduced.

An osseointegratable prosthetic device suitable for implantation via a one-step surgical process includes a threaded insertion end, an externally accessible tool interface end, and an intermediately arranged scaffold portion defining recesses that permit ingrowth of skeletal tissue. Such recesses may include multiple longitudinal fins as well as transverse ribs, which may embody or be coated with porous material to promote bone ingrowth. A split flange portion includes discontinuous portions and may permit pretensioning of the device. The device may be fabricated as a unitary body structure from thermoplastic materials using techniques such as fused filament fabrication (a form of 3D printing). The osseointegratable prosthetic device enables one-step surgical implantation without requiring separately implantable fixture/sleeve and abutment portions according to conventional osseointegratable prosthetics. Methods for fabricating an osseointegratable prosthetic device are further provided.

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.

The present invention provides a three-dimensional bioprinter for fabricating cellular constructs such as tissues and organs using electromagnetic radiation (EMR) at or above 405 nm. The bioprinter includes a material deposition device comprising a cartridge for receiving and holding a composition which contains biomaterial that cures after exposure to EMR. The bioprinter also includes an EMR module that emits EMR at a wavelength of about 405 nm or higher. Also provided is a bioprinter cartridge which contains cells and a material curable at a wavelength of about 405 nm or greater. The cells are present in a chamber and are extruded through an orifice to form the cellular construct.

Methods of fabricating a liner for reducing motion between a socket and a skeletal structure in a body part are described. Methods include selecting a plurality of compression areas, lying the compression areas along the longitudinal axis of the liner, and spacing the compression areas circumferentially around the liner. The durometer, radial thickness, width, and longitudinal dimension of the compression areas are selected to compress soft tissue of the body part against the skeletal structure to reduce motion of the skeletal structure towards a wall of the socket. Methods also include selecting a plurality of attachment areas on the liner and affixing a plurality of attachment area materials to the plurality of attachment areas. The durometer, radial thickness, width, and longitudinal dimension of the attachment area materials are selected to compress soft tissue of the body part and reduce motion of the skeletal structure towards a wall of the socket.
