  • Patent number: 10482187
    Abstract: A custom brace and method for fabricating the custom brace includes marking a body with reference points and/or other indicators. Multiple images of the body from multiple angles are then obtained. The images are used to determine the contours of the body and the other markings are located and used to design the custom brace. Fenestrations can be added to the brace design. The custom brace can be fabricated with the fenestrations as a single piece structure or in multiple pieces that are assembled to complete the custom device.

  • Patent number: 10479028
    Abstract: A socket for a prosthetic limb is created by making a cast of a residual limb. Marks can be applied to the interior surface of the cast to indicate the locations of anatomical features of the residual limb. The marked interior surface can be scanned and the scan data can be sent to a master fabrication center. The scan data can be modified and a master can be produced from the modified scan data. The socket can then be formed from the plastic material on the master.

  • Patent number: 10479068
    Abstract: There is provided an additive manufacturing system comprising a vertical stage (also known as a z-stage) that moves the object being created along an axis of motion that is not perpendicular to the image plane (non-parallel to the z-axis of the image plane). By moving the build platform, upon which the additively manufactured object is being supported, along a predetermined axis of motion, such as one adapted to the dominant axis of the object design, the additive manufacturing system is capable of making larger objects, shortening build times, improving part resolution, and/or reducing the volume of photocurable material needed, among other benefits.

  • Patent number: 10285829
    Abstract: A method for creating tubular inserts is useful for creating custom fitted inserts that correspond to the anatomy of a patient and solve the problem of pressure points, wear of the implant, damage to surrounding tissue, and denting. Surface measurements of the affected portion of a patient's internal cavity are obtained. Those measurements are used to design a core. The core is 3D printed with a soluble material. The core is wrapped with a thin filament or film such that the contours from the core develop on the outer surface of the covering. The covering is hardened and the core is dissolved away, leaving a custom-made implant device that can be deposited in the patient's cavity.

  • Patent number: 10238520
    Abstract: An adjustable brace includes a first portion for supporting one surface of a patient and a plurality of adjustable portions that allow the internal cross section of the brace to be adjusted. When a limb is injured, a patient may have a swollen limb and the adjustable brace can be set to a large cross section. As the limb heals, the swelling decreases and the limb cross section also decreases due to atrophy. The adjustable couplings are adjusted to reduce the cross section to properly fit the limb of the patient and provide proper protection and support during the healing process.
