Patent number: 11123210Abstract: It is the object of the invention to provide a knee bracing system that bolsters the body's natural ligaments to reduce the knees proneness to injury or re-injury. The invention is a cable system that acts much like the body's natural way that resists the forces that cause excessive joint movement and injury to the ACL and or MCL. As the leg travels through the range of motion the cables provide external hyper extension, bending, and rotation support preventing the tibia bone from moving forward (hyper extending) or twisting (lateral rotation) and or laterally bending with respect to the femur.Type: GrantFiled: April 22, 2013Date of Patent: September 21, 2021Assignee: MOBIUS TECHNOLOGIES, LLCInventor: Darren Fleming

Patent number: 10596024Abstract: A dynamic platform with extending struts has fastened thereto a bi-directional torsional power unit to selectively deliver force opposing either extension or flexion, and to provide assistance in a respective opposite direction. The power unit is threadably mounted on a hinge pin (spline) centrally located on the platform, and is latched to a catch assembly radially located thereto, the hinge pin of the platform communicating with one end of a torsion spring of the power unit and the catch assembly communicating with another end of the torsion spring, to selectively deliver the extension/flexion force. The power unit can be detached, with simple manual operation of the catch assembly, without tools, flipped over and reattached to the same platform attachment points to switch (reverse) extension torque to flexion torque and vice versa.Type: GrantFiled: July 30, 2018Date of Patent: March 24, 2020Assignee: Ultraflex Systems, Inc.Inventor: Mark DeHarde

Patent number: 10575831Abstract: An evidence retaining enclosure for receiving a limb for purposes of retaining DNA evidence and the like. The enclosure includes an elongated body having a first open end and a second closed end, with the limb adapted to being inserted into the open end such that an end thereof is retained in proximity to the closed end. At least one pair of circumferential extending straps are associated with the open end for sizing about a projecting dimension of the limb, the straps being inter-engaged in order to secure the enclosure in place. The body further includes first and second telescoping portions, the first portion integrating the closed end and the second portion integrating the circumferential straps. Axial fixing straps extend between the first and second telescoping portions for fixing an inter-telescoping relationship established therebetween.Type: GrantFiled: July 3, 2017Date of Patent: March 3, 2020Inventor: Raymond R. Shaw

Patent number: 10561506Abstract: An orthopedic joint system having an upper part and a lower part mounted thereon so as to pivot about a pivoting axis, and a pawl which prevents in a locking position any relative movement between the upper part and the lower part about the pivoting axis, and allows in a release position a relative movement about the pivoting axis. The pawl, in the locking position, interlockingly engages a locking element and can be shifted to the release position via a pull element, a first end of the pull element being attached to the upper part or to the lower part and moved along the outside of the pawl in a curved section, and a second end of the pull element being provided with an actuating device which causes the curved section to be shortened and the pawl to be moved to the release position when the actuating device is actuated.Type: GrantFiled: July 9, 2015Date of Patent: February 18, 2020Assignee: OTTOBOCK SE & CO.
