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 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.

A prosthetic liner having a lower longitudinal stretch in the distal region than in either the proximal or optional intermediate region. The distal region may stretch anywhere from 0-30% vertically and 10-200% horizontally as compared to the proximal region's vertical stretch of 55-125% and 100-175% horizontally. The stretch of the liner at various pressure sensitive regions of a residual limb can also be lowered or heightened depending on the area. A variety of stitches may be used at the distal end to implement this lowered longitudinal stretch. Preferably, the liner is made of a stretchable material. The liner also has an interior layer of elastomer gel. The design of this prosthetic liner is primarily to prevent the “pistoning” of the amputee's residual limb within the liner and for comfort over pressure-sensitive areas of the residual limb. The liner also includes the use of a low extensibility material which is adhered to the fabric portion of a prosthetic liner or orthotic liner either internally or externally and limits the longitudinal movement while allowing for transversal movement. The customizable nature of the invention allows for shaping and personalization depending on the needs of the user.

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.

Devices and methods for obtaining external shapes and internal tissue geometries, as well as tissue behaviors, of a biological body segment are provided. A device for three-dimensional imaging of a biological body segment includes a structure configured to receive the biological body segment, the structure including a first array of imaging devices disposed about a perimeter of the device to capture side images of the biological body segment and a second array of imaging devices disposed at an end of the device to capture images of a distal portion of the biological body segment. The second array has a generally axial viewing angle relative to the perimeter. A controller is configured to generate a three-dimensional reconstruction of the biological body segment based on cross-correlation of captured images from the first and second arrays.

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.

A low extensibility material for use in prosthetics and orthotics. The low extensibility material is adhered to the fabric portion of a prosthetic liner or orthotic liner either internally or externally and limits the longitudinal movement while allowing for transversal movement. The customizable nature of the invention allows for shaping and personalization depending on the needs of the user.

An adjustable seal system includes a suspension liner having a liner body and an outer surface. A plurality of seal bands are located along a height of the liner body. A seal component is arranged for removably securing to the liner body. The seal component includes open upper and lower ends defining an opening therethrough and an internal surface arranged to frictionally engage at least one of the seal bands and secure on the outer surface of the liner. The seal component also includes an upper portion descending to at least one seal, and a lower portion.

A system and method for method including receiving data representing coordinates of a shape of a body part, forming a model of a flexible inner liner based upon the received data, the flexible inner liner configured to be placed over the body part, receiving, as input, a thickness and an offset of the model of the flexible inner liner, assigning a default density to an internal structure of the model; and varying the default density of the model without changing an outer geometry of the model to create a modified model of the flexible inner 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.
