Patent number: 9959683Abstract: A 3-D model of a body part is created by using an object comprising markers, fixation members, and struts. The method involves first and second roentgenograms of the body part and the object disposed between an x-ray source and an x-ray imager. It then determines first and second sets of distances between projections of the markers or the struts, and determines first and second 3-D positions of the x-ray source and of the object with respect to the x-ray imager using predetermined distances between the markers or struts and the first and second sets of distances between their projections. The method then aligns the first and second 3-D object projections in a 3-D reference frame using the 3-D positions of the markers or struts with respect to the x-ray imager in the two orientations. The method creates the 3-D model of the object based on the 3-D object projections.Type: GrantFiled: March 15, 2013Date of Patent: May 1, 2018Assignees: Texas Scottish Rite Hospital for Children, AMEI Technologies, Inc.Inventors: Konstantin Evgenevich Mikheev, Petr Stanislavovich Vvedenskiy, Alexander Alexandrovich Morenko, Dmitry Alexandrovich Sivachev, Mikhail Samchukov, Alexander Cherkashin

Publication number: 20130245625Abstract: An orthopedic fixation system having two rings or other base/frame elements separated by a plurality of struts. The struts are attached to the rings by a combination of a attachment mechanism having at least two degrees of movement each, and at least one connecting mechanism. The connecting mechanisms may be moveably or non-moveably connected to one or more tracks located on either or both rings of base elements. A combination of these elements provides a fixation device that allows for six degrees of freedom of movement between the rings or other base elements.Type: ApplicationFiled: April 29, 2013Publication date: September 19, 2013Applicant: AMEI TECHNOLOGIES, INC.Inventors: Paul Vasta, David Crook, Michael Thomas

Publication number: 20130218217Abstract: A fixation device may be used for supporting and/or stretching an injured body part. An exemplary fixation device uses a thumb wheel control element to provide controlled rotational micromovements of a joint. The control element and its associated drive system allow for movement along a particular axis, while the position remains fixed with relation to the other axis. In addition, the fixation device may incorporate a drive system that introduces a simultaneous longitudinal translation with rotation, in order to provide for a common point of origin of rotation between the fixation device and the affected body part supported by the fixation device.Type: ApplicationFiled: March 28, 2013Publication date: August 22, 2013Applicant: AMEI TECHNOLOGIES, INC.Inventor: AMEI TECHNOLOGIES, INC.

Publication number: 20130131675Abstract: A fixator system includes an active strut that that can be gradually or acutely adjusted. Adjustments can be made in six degrees of freedom. Embodiments of the active strut can provide for two of the six degrees of freedom being about a first common point of rotation, and another two of the six degrees of freedom being about a second common point of rotation. Embodiments of the fixator can include one or more active struts in combination with one or more passive struts. The passive struts can be rigidly locked or can be unlocked so as to be freely and acutely adjustable while gradual or acute adjustments are made using the one or more active struts.Type: ApplicationFiled: January 19, 2013Publication date: May 23, 2013Applicant: AMEI TECHNOLOGIES, INC.Inventor: AMEI Technologies, Inc.

Patent number: 8398687Abstract: Disclosed embodiments describe a volar plate generally for use treating distal volar fractures. The volar plate is designed in accordance with anatomical features and is generally Y-shaped, having a wider distal head portion that tapers to a narrower proximal body portion. A plurality of holes in the distal head of the volar plate allow for fixation means to fix the position of bone fragments with respect to the volar plate. The plurality of holes in the distal head basically form two substantially non-linear rows, with the distal row generally curving inward proximally and the proximal row generally curving outward distally such that the fixation means inserted through the holes generally converge. A central cavity may be located in the proximal body of the volar plate to promote bone growth, and mounting screws may border the central cavity on either side to provide secure support. Additionally, K-wire holes may be included which are visually linked to corresponding holes in the distal head.Type: GrantFiled: December 6, 2006Date of Patent: March 19, 2013Assignee: AMEI Technologies, Inc.Inventors: Paul J.
