A prosthetic appendage for attachment to an outer extremity of an amputated limb that is composed of modular elements fabricated by three-dimensional printing. In one embodiment the prosthetic appendage is a leg. The prosthetic leg includes a foot portion and a plurality of modular and three-dimensionally printed limb elements. One of the plurality of limb elements is pivotally coupled to the foot portion and another of the limb elements is configured at one end to receive the outer extremity of the amputated leg. In another embodiment of the present invention the prosthetic appendage is a hand. The prosthetic hand includes a wrist element with one end configured to receive the outer extremity of an amputated hand, a base portion attached to the wrist element and a plurality of modular and three-dimensionally printed finger elements selectively coupled to adjacent finger elements or the base to form prosthetic fingers.

Systems and methods for creating custom-fit prosthetic devices, orthotic devices, and related medical devices via three-dimensional printing (3D printing) or additive manufacturing techniques are described. Through the described systems and methods, a residual limb or other body part of a patient is scanned and analyzed to determine measurements and characteristics of the residual limb. The measurements and characteristics of the residual limb are used to design a customized device for the residual limb. The customized device uses multiple different materials. For example, the customized device may use a first material for a frame and a second material for a liner, wherein the first material is more rigid than the second material. The customized device is fabricated using a three-dimensional printer that is capable of printing and bonding multiple different materials at the same time.

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 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 lower limb modular prosthetic system that may be fabricated by a 3D printer capable of printing with composite fiber filament, nylon, or metal. The production process may include a 3D printer that is capable of routing fiber in specifically programmed patterns. The components of the prosthetic system may be designed for direct patient end-use, and may be energy returning in nature.

A passive prosthetic foot enables a below-knee amputee to walk with near able-body walking motions. The prosthetic foot includes a resilient heel that enables the heel to strike a walking surface more softly than in the prior art and more accurately transition the leg from swing phase to stance phase. The prosthetic foot is modeled generally as a wide Bzier curve, and the foot is characterized according to a set of at least 12 variables, including h, C1d, C2x, C2y, C2d, C3x, C3y, C3d, C4x, C4d, C5d and C6d, where C3y is heel size, C4x is heel geometry and C6d is curve intersection location. The variables are optimized to minimize a difference between a normal lower leg trajectory during gait and a modeled trajectory that includes the prosthetic foot.
