Patent number: 11937797Abstract: 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: January 2, 2020Date of Patent: March 26, 2024Assignee: DePuy Synthes Products, Inc.Inventors: William C. Horton, John Riley Hawkins, Christopher L Ramsay, Edward B. Zalenski, Alexander Grinberg, Hassan Serhan, Ernest Quintanilha

Patent number: 11311318Abstract: 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 seats a spherical head of the bone anchor and a spinal fixation element, a compression member seated within the receiver member, proximally of the head of the bone anchor, and a closure mechanism seated within the receiver member, proximally of the compression member. One or more of the receiver member, the compression member, and the closure mechanism can have gripping features thereon configured to secure the bone anchor and/or the spinal fixation element within the receiver member, thereby reducing a risk of slippage of the bone anchor and/or the spinal fixation element with respect to the receiver member.Type: GrantFiled: June 25, 2019Date of Patent: April 26, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Frank Spratt, Philip A.

Publication number: 20210212730Abstract: 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 surface of the bone. In an exemplary embodiment, a bone anchor assembly is provided that includes a bone anchor configured to engage bone, a receiver member for seating a head of the bone anchor, and a compression member for securing the bone anchor at fixed angle with respect to the receiver member when the compression member is seated within the receiver member. Corresponding engagement features of the compression member and the receiver member can be engaged in a secured configuration to inhibit or prevent removal of the compression cap from the receiver member and optionally to substantially prevent longitudinal and/or rotational movement of the compression member with respect to the receiver member.Type: ApplicationFiled: March 31, 2021Publication date: July 15, 2021Applicant: Medos International SarlInventors: Thibault Chandanson, Ernest Quintanilha, Frank Spratt, Philip A.

Patent number: 10786284Abstract: 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: February 15, 2019Date of Patent: September 29, 2020Assignee: Medos International SarlInventors: Frank Spratt, Ernest Quintanilha, Thibault Chandanson
