Patent number: 9788869Abstract: A spinal fixation element rotation instrument with two lever arms is provided. The lever arms are connected to each other at distal ends thereof. The second lever arm rotates relative to the first lever arm. The distal ends of the first and second lever arms are adapted to couple to a spinal fixation element. The distal ends of the lever arms may have a dual ratchet feature that prevents rotation in a set direction. When one arm rotates back and forth, the other arm is held stationary. As a result, the spinal fixation element rotates in a predetermined direction and is prevented from rotating back toward its initial position. The direction of the rotation of the spinal fixation element may be set using knobs or switches provided at a proximal end of one or both of the lever arms.Type: GrantFiled: February 27, 2009Date of Patent: October 17, 2017Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Shawn D.

Patent number: 9782265Abstract: An implant is insertable in the joint space to separate bones of the joint. The implant has two endplates each configured to engage a separate articulating bone of the joint, and a threaded member positioned between the two endplates and configured to increase the space between the two endplates when the threaded member is rotated. A rotatable gear is engaged with the threaded member, and is engageable with a rotating gear of a connected implantation tool, so that rotation of the gear on the tool causes rotation of the threaded member and expansion of the implant to separate the bones. Connector portions on the tool and the implant may be rotated together to securely engage the implant and the tool so that the gears of the tool and the implant can be rotated using an actuator outside of the body, when the implant is inside the body.Type: GrantFiled: February 15, 2013Date of Patent: October 10, 2017Assignee: Globus Medical, IncInventors: Mark Weiman, John Matthews, Kevin Gahman, Colm McLaughlin, Chad Glerum, Adam Friedrich, Jason Gray, Marcin Niemiec, Michael Harper

Patent number: 9743964Abstract: Described is a locking intramedullary nail for insertion in the medullary cavity of hollow bones for treating bone fractures or for joint stiffening. The nail comprises an oblong shaft having at least one holder for a locking screw. In the region of an opening a roller or ball-shaped sleeve having a bore for receiving the locking screw is arranged. The sleeve which is supported in the shaft in a freely pivotable manner can be locked in a positionally stable manner in the shaft. This affords the ability to introduce the locking screws during the implantation of the intramedullary nail at an optimum angle for the respective anatomical or pathological situation of the patient and to subsequently lock it permanently at a constant angle.Type: GrantFiled: May 20, 2008Date of Patent: August 29, 2017Assignee: OT MEDIZINTECHNIK GMBHInventors: Ulrich Schreiber, Stefan Eichhorn

Patent number: 9724135Abstract: Provided are methods and systems for enlarging a spinal canal of a vertebra. Using the methods and systems disclosed the spinal canal of the vertebra is enlarged by cutting the posterior arch portion of the vertebra to create one or two implant receiving spaces in the posterior arch portion. The cutting of the posterior arch portion is completed through a minimally invasive approach. Once cut, the detached portion of the posterior arch portion is repositioned and an implant is positioned in the implant receiving space of the posterior arch portion to thereby enlarge the spinal canal such that the spinal cord is no longer compressed. The insertion of the implant is also completed through a minimally invasive approach.Type: GrantFiled: December 16, 2011Date of Patent: August 8, 2017Assignee: DePuy Synthes Products, Inc.Inventors: David Koch, Simon Kamber, Reto Halbeisen, Lukas Giger, Michael Guetlin, Felix Aschmann, Jann-Paul Suedkamp, Marco Messias, Tom Overes, Bruno Laeng, Roger Berger, Joern Richter
