Publication number: 20170172754Abstract: An expandable tube having a substantially semicircular unexpanded shape is inserted into the disc space after the disc material has been removed therefrom. A plurality of expandable lockable rings are passed over this tube in their unexpanded states and positioned along the anterior edge of the endplates. The tube is then expanded, thereby forcing the rings to expand. The rings hold their final expanded configuration via a one-way locking mechanism. Once sufficient distraction is achieved and the rings locked, the tube is collapsed and removed, thereby leaving the expanded, locked rings behind to support the disc space.Type: ApplicationFiled: March 9, 2017Publication date: June 22, 2017Applicant: DePuy Synthes Products, Inc.Inventors: William Frasier, Narendren Renganathan, Glen Presbrey, Michael A. Fisher, John Riley Hawkins

Patent number: 9180022Abstract: An instrument system for performing spinal surgery that helps provide optimal plate selection as well as an improved temporary alignment and retention means, without the need to penetrate the vertebral bodies with temporary fixation pins. The instrument system of the present invention has a clip that possesses features that temporarily center, align and position the plate to the interbody cage. This clip mates with the cage by hugging the outside parameters of the cage, as well as within the window (central through-hole) of the cervical plate.Type: GrantFiled: June 28, 2013Date of Patent: November 10, 2015Assignee: DePuy Synthes Products, Inc.Inventors: Bacem Georges, Thomas Gamache, Carl Legge, Glen Presbrey

Patent number: 8882810Abstract: A device intended for the treatment of spinal stenosis. This device is an inter-spinous spacer that is introduced through a single posterior incision. It uses a single piece insertion technique with a unilateral approach. The surgeon does not need to access the opposite side of the spinous process. It allows the user infinite adjustability in distraction height with a single locking mechanism.Type: GrantFiled: July 27, 2012Date of Patent: November 11, 2014Assignee: DePuy Synthes Products, LLCInventors: Christopher Ramsay, Christine Rusbarsky, Katherine Selover, Glen Presbrey, Hassan Serhan

Patent number: 8685029Abstract: An instrument for reducing a spinal rod includes a reduction member sized and shaped to be positioned about an anchor extension connected to a bone anchor, an actuator assembly connected to the reduction member and operable to move the reduction member distally relative to the anchor extension along a longitudinal axis of the anchor extension, and a connection mechanism for removable and replaceable connection of the actuator assembly to a proximal end of the anchor extension. The connection mechanism is adjustable between a first position in which the connection mechanism connects the actuator assembly to the proximal end of the anchor extension and a second position in which the connection mechanism and the actuator assembly are released from the anchor extension.Type: GrantFiled: September 26, 2011Date of Patent: April 1, 2014Assignee: DePuy Synthes Products, LLCInventors: Sara Dziedzic, James Donahue, Glen Presbrey

Publication number: 20120316652Abstract: Various spinal implants and methods for stabilizing the spine are provided. In one exemplary embodiment, a spinal implant is provided having an expandable container with an interior volume that is selectively expandable between a compressed condition and an expanded condition. The expandable container is coupled to a superior endplate member having a bone-contacting surface and an engagement surface effective to mate with a superior surface of the expandable container, and an inferior endplate member having a bone-contacting surface and an engagement surface effective to mate with an inferior surface of the expandable container. In addition, at least one inlet port is formed in the expandable container and is effective to communicate a fluid to at least one cavity disposed within the interior volume of the expandable container.Type: ApplicationFiled: July 30, 2012Publication date: December 13, 2012Applicant: DEPUY SPINE, INC.Inventors: Naren Renganath, Steven Connolly, Michael Alan Fisher, Glen Presbrey
