The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in an H-shape with a first end forming a first split prong and a second end forming a second split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and H-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. Other embodiments are also disclosed.

A mechanical interface connecting a biological body segment, such as a limb, portion of a limb or other body segment, to a wearable device such as a prosthetic, orthotic or exoskeletal device, is fabricated by quantitatively mapping a characterized representation of the body segment to form a digital representation of the mechanical interface shape and mechanical interface impedance. The mechanical interface includes a continuous socket defining a contoured inside surface and a contoured outside surface, and includes a material having an intrinsic impedance that varies through the material, so that the intrinsic impedance varies along the contoured inside surface.

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.

A unibody transtibial prosthetic device includes a socket personalized for a specific patient's residual limb. A pylon extends from the socket, the pylon being a unitary polymer structure of interconnected elongated supports having open spaces therebetween. The device also includes a foot-ankle complex, the foot-ankle complex being a unitary polymer extending from the pylon, the foot and ankle unitary structure being shaped to provide multi-axial dynamic flex to enable dorsiflexion, plantar flexion, inversion and eversion motion for smooth symmetric gait performance and energy capture and return. The socket, pylon and foot-ankle complex are portions of a unibody.

Disclosed herein are a method and system for producing a digital model of a customised device, comprising the steps of: importing a first digital file of a base part; importing a second digital file of a target shape; determining a warping interpolation function based on source point positions associated with the base part and target point positions associated with the target shape; and applying the warping interpolation function to the points of said base part to generate a model of said customised device.

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.

The invention relates to a medical container unit for designing and/or manufacturing an implant, comprising a plurality of container subunits, each of which forms a sector, is equipped with at least one means for designing and/or manufacturing an implant, and is formed by self-supporting partial substructures on at least two sides.

An upper extremity prosthesis may include a prosthetic hand including a prosthetic thumb having a base and a tip, and a prosthetic index finger having a base and a tip. Actuators may be coupled to the upper extremity prosthesis. Prosthetic flexion tendons may have first ends operably coupled to the actuators and second ends coupled to the tips of the thumb and the index finger. Biasing systems may be operably coupled to the prosthetic thumb and the index finger. Upon actuation of the actuators in a first direction, the prosthetic flexion tendons cause the thumb and index finger to flex. Upon actuation of the linear actuators in a second direction opposite the first direction, the biasing systems cause the thumb and index finger to extend.

A method for manufacturing a customized apparatus with a shape adapted to a specific user's morphology, or a mold for such an apparatus, includes obtaining a description of a generic apparatus, or of the mold for such an apparatus, the generic apparatus being adapted to a generic morphology. A description of the generic morphology and a description of the specific user's morphology is obtained. The descriptions of the generic morphology and of the specific user's morphology are processed to identify a geometric transformation mapping together the generic morphology and the specific user's morphology. The geometric transformation is applied to the description of the generic apparatus, or the description of the mold for such apparatus, in order to define the description of the customized apparatus or the mold therefor. The customized apparatus is then manufactured.
