Publication number: 20240023998Abstract: Connectors are disclosed herein that can be used to attach a rod to a bone anchor assembly that is already occupied by a separate rod. Various ways of attaching the connector to the bone anchor assembly are disclosed, including arrangements in which the connector is locked to the bone anchor, arrangements in which the connector is constrained in one or more degrees of freedom relative to the bone anchor, arrangements in which the connector is adjustable in one or more degrees of freedom relative to the bone anchor, and arrangements that include a spherical articulation joint. In some embodiments, attachment of the connector to a bone anchor can be aided with the use of a positioner. The geometry of the connector can be selected to minimize the offset between a first rod received in the bone anchor assembly and a second rod received in the connector, for example using an angled or curved rod recess and/or a fastener, or set screw, that is offset from the center of the rod or angled relative to the bone anchor.Type: ApplicationFiled: September 30, 2023Publication date: January 25, 2024Inventors: Robert Carruth, John Dieselman, Kevin Lee, J. Riley Hawkins

Patent number: 11399734Abstract: Methods, systems, and devices are provided for guiding surgical instruments using radio frequency (RF) technology. In general, the methods, systems, and devices can allow a trajectory, e.g., an angular approach, of a surgical instrument relative to a patient to be identified during use of the instrument in a surgical procedure being performed on the patient. The trajectory can be identified using a plurality of RF modules. The methods, systems, and devices can allow the trajectory to be compared to a predetermined trajectory so as to identify whether the trajectory matches the predetermined trajectory. A result of the matching can be communicated to a user of the instrument. Based on the result, the user can maintain the trajectory, e.g., if the trajectory matches the predetermined trajectory, or can adjust the trajectory to closer align the trajectory with the predetermined trajectory, e.g., if the trajectory does not match the predetermined trajectory.Type: GrantFiled: May 11, 2017Date of Patent: August 2, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Sean P. Selover, Joseph Hernandez, John Riley Hawkins, John Dieselman, John Paul Griffin, Jennifer DiPietro

Publication number: 20220192843Abstract: A system for delivering flowable biomaterial to an intervertebral disc space between adjacent vertebral bodies includes a delivery body defining a proximal end, a distal end spaced from the proximal end along a longitudinal direction, a cannulation extending from the proximal end to an opening adjacent the distal end, and a distal region including a tip that extends to the distal end. The distal region defines a maximum height at a location proximal of the distal end and measured along a second direction perpendicular to the longitudinal direction. The distal region is for indicating a distance between the adjacent vertebral bodies. The system includes a carrier having a longitudinally elongate channel for carrying biomaterial and being insertable within the cannulation, as well as an advancement member configured for insertion within the cannulation to forcibly advance the biomaterial from the cannulation, through the opening, and into the disc space.Type: ApplicationFiled: March 14, 2022Publication date: June 23, 2022Inventors: James Murray, John Riley Hawkins, Benjamin Cleveland, Alicia McDermott, Roman Lomeli, John Dieselman, Stephen Bornhoft, Christopher Ramsay, Nicholas Pavento, Jan Klett, Stephane Gully, Eric Buehlmann, Thomas Gamache, Roger Berger

Patent number: 9566098Abstract: An assembly for rigid bone fixation includes a plate and a screw. The screw can be rotated freely within the plate in a non-locking configuration to secure the plate against the bone. A locking mechanism is engaged to prevent the screw from moving relative the plate. In one embodiment, the plate includes a threaded portion and a non-threaded portion. The screw head rotates within the non-threaded portion to tighten the screw and pull the plate against the bone. The locking mechanism can include a moveable nut that rotates within the threaded portion of the plate to lock the screw and plate in a locking mode. The assembly can be used for rigid fixation of bones that experience cyclic loads, such as the sternum and mandible. Methods of rigid bone fixation are also described.Type: GrantFiled: April 19, 2012Date of Patent: February 14, 2017Assignees: University of Massachusetts, Worcester Polytechnic InstituteInventors: Raymond Dunn, Kristen Billiar, Janice Lalikos, Alexander Christakis, John Dieselman
