Patent number: 10226282Abstract: A bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, a compression member positioned within the receiver member, and a closure mechanism including an outer set screw and an inner set screw. The outer set screw delivers a distal force to the compression member to fix the bone anchor relative to the receiver member. The proximal surface of the compression member has a shape configured to restrict deformation of the compression member arms including motion of the compression member arms relative to each other. The distal surface of the outer set screw has a shape that is complementary to the shape of the proximal surface of the compression member.Type: GrantFiled: August 31, 2017Date of Patent: March 12, 2019Assignee: Medos International SarlInventors: Frank Spratt, Ernest Quintanilha, Thibault Chandanson

Patent number: 9918747Abstract: Various exemplary methods and devices are provided for fixing bone anchors to bone. In general, the methods and devices can allow for a bone anchor to be fixed to a bone at a desired angle to a receiver member. In an exemplary embodiment, a bone anchor assembly is provided that includes a bone anchor configured to engage bone, a receiver member that polyaxially seats a spherical head of the bone anchor, and a compression member seated within the receiver member, proximally of the head of the bone anchor. The compression member can have a distal end with gripping features thereon configured to create at least one line contact and/or one band contact with the head of the bone anchor, thus providing a firm grip on the head of the bone anchor and reducing a risk of slippage of the bone anchor with respect to the receiver member.Type: GrantFiled: December 11, 2015Date of Patent: March 20, 2018Assignee: DePuy Synthes Products, Inc.Inventors: Frank Spratt, Philip A. Cormier, Ernest Quintanilha, Sara Dziedzic, Nicholas Pavento, Derek Shaw, Thibault Chandanson

Publication number: 20170360491Abstract: Bone anchor assemblies and methods are provided having a multi-component bone anchor that is configured to allow the shank of the bone anchor to be bottom loaded into a receiver member. In one embodiment, a bone anchor assembly is provided having a shank with a distal threaded portion and a proximal head portion, a ball having a spherical exterior surface and a central lumen sized to receive the head portion of the shank, and a clip configured to be engaged between the head portion and the ball such that the clip is effective to lock the ball in engagement with the shank.Type: ApplicationFiled: August 31, 2017Publication date: December 21, 2017Inventors: Frank Spratt, Thibault Chandanson, Ernest Quintanilha, Shawn D. Stad, Ralf Klabunde

Patent number: 9833263Abstract: Bone anchor assemblies are disclosed herein that include one or more features for indicating the relative positioning of the receiver member and the shank, or for selectively maintaining the receiver member and the shank in a fixed relative position. For example, the head of the shank can include a surface feature that interacts with a drag ring to provide tactile or audible feedback when the shank is positioned at a particular orientation with respect to the receiver member. By way of further example, the head of the shank and a compression cap disposed in the receiver member can each include engagement features that cooperate to allow for selective locking of the orientation of the shank with respect to the receiver member.Type: GrantFiled: April 13, 2015Date of Patent: December 5, 2017Assignee: Medos International SarlInventors: Thibault Chandanson, Frank Spratt, Ernest Quintanilha, Philip Cormier

Patent number: 9827024Abstract: Various devices and methods for breaking and retaining surgical reduction tabs are provided. In general, the devices and methods can allow a single surgical instrument to break a plurality of surgical reduction tabs off one or more surgical implants and retain the broken tabs within the instrument. In an exemplary embodiment, a surgical instrument can include an opening at a distal end thereof that is configured to receive a surgical reduction tab therein when the tab is connected to a surgical implant. A retention element at least partially disposed within the instrument can be configured to engage the tab received in the opening so as to hold the tab securely within the instrument. With the tab received in the opening and held by the retention element, the surgical instrument can be configured to be manipulated to break the tab off the surgical implant. The broken tab can be retained within the surgical instrument by being held therein by the retention element.Type: GrantFiled: January 12, 2017Date of Patent: November 28, 2017Assignee: DePuy Synthes Products, Inc.Inventors: Philip A.

Patent number: 9622779Abstract: A novel posterolateral inter-muscular approach has been developed to access the cervical spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises i) an anterior superior border of the trapezius muscle; ii) an anterior inferior border of the splenius capitis muscle, and iii) a posterior superior border of the levator scapulae muscle. Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.Type: GrantFiled: September 26, 2012Date of Patent: April 18, 2017Assignee: DePuy Synthes Products, Inc.Inventors: William C Horton, John Riley Hawkins, Christopher L Ramsay, Edward Zalenski, Alexander Grinberg, Hassan Serhan, Ernest Quintanilha
