Bi-directional fixating/locking transvertebral body screw/intervertebral cage stand-alone constructs
Patent number: 10238505Abstract: A bi-directional fixating transvertebral (BDFT) screw/cage apparatus is provided. The BDFT apparatus includes an intervertebral cage including a plurality of internal angled screw guides, a plurality of screw members, and a cage indentation adjacent to the screw guides that independently or supplemented by other screw locking mechanisms prevents the screw members from pulling out of the internal angled screw guides. The internal angled screw guides orient a first screw member superiorly and a second screw member inferiorly. The intervertebral cage is adapted for posterior lumbar intervertebral placement, anterior lumbar intervertebral placement, anterio-lateral thoracic intervertebral placement, or anterior cervical intervertebral placement.Type: GrantFiled: August 16, 2017Date of Patent: March 26, 2019Assignee: Moskowitz Family LLCInventors: Nathan C. Moskowitz, Mosheh Moskowitz, Ahmnon D. Moskowitz, Pablo A. Valdivia Y. Alvarado -
Patent number: 10213216Abstract: A method for providing therapy to a patient, the method comprising: providing microfracture therapy to the acetabular cup of the patient, wherein providing microfracture therapy to the acetabular cup of the patient comprises forming at least one hole extending from the acetabular shelf to the cortical bone bed of the acetabular cup, such that blood may flow from the cancellous bone underlying the cortical bone bed to the surface of the cortical bone bed, whereby to form a blood clot at the surface of the cortical bone bed.Type: GrantFiled: May 28, 2014Date of Patent: February 26, 2019Assignee: Pivot Medical, Inc.Inventors: James Flom, Julian Nikolchev

Patent number: 10206694Abstract: Methods and drill guide systems that provide internalization of the biceps tendon with use of fixation devices such as the Arthrex BicepsButton™ or Pectoralis Button tensioned outside a smaller converged drill hole. The technique converges two angled drill holes and use the button to fixate a reinforced (whipstitched) biceps tendon into a single bone versus stabilizing two bones. The biceps tendon is being pulled into the larger of the drilled holes and fixed by the button outside of the smaller drilled hole.Type: GrantFiled: January 30, 2015Date of Patent: February 19, 2019Assignee: ARTHREX, INC.Inventors: Dustin T. Libby, William C. Benavitz, Thomas Dooney, Jr., Harri Helio, James J. Guerra

Patent number: 10201358Abstract: Aligning the syndesmosis joint by a novel device and method includes establishing a first plane by attaching a bone plate to the posterolateral aspect of the distal fibula. A second transverse plane arranges perpendicular to the first nominal plane. A syndesmosis targeting guide device includes a post having a post axis extending perpendicular to the first plane and in the second plane. The device includes a curvilinear slider guide extending along an arc in the second plane. The slider is positioned to a first position and fixing that first position to establish a fixed entry point in the fibula wherein the fixed entry point lies in the second plane and further thereby establishing a desired trajectory in the second plane wherein the trajectory includes the fixed entry point based on the slider first position.Type: GrantFiled: June 26, 2015Date of Patent: February 12, 2019Assignee: Acumed LLCInventors: Andrew W. Seykora, James W. Michelinie

Patent number: 10166083Abstract: A computer-assisted surgery system comprises instruments adapted to be used to perform tasks related to surgery. A reference device is in a fixed relation to a bone. A rotating magnet creates a magnetic field plane, the rotating magnet being connected to one of the instrument and the reference device. A magnetometer on the other of the instrument and the reference device produces signals as a function of at least its orientation relative to the magnetic field plane. A processing unit tracks said orientation of the instrument relative to the bone using said signals from the magnetometer subjected to the magnetic field plane.Type: GrantFiled: August 21, 2017Date of Patent: January 1, 2019Assignee: ORTHOSOFT INC.Inventors: Francois Paradis, Joel Zuhars, Karine Duval, Mathieu Chevrier
