Patent number: 12133641Abstract: The present disclosure relates to methods and devices for surgically manipulating tissue. In general, the methods and devices can include an elongate retractor shaft having a distal retractor tip that is configured to manipulate tissue, for example the tip can be configured to separate muscle and nerve fibers surrounding a vertebra. The elongate retractor shaft can include an illumination source such that at least a portion of the surgical field is illuminated by the device when the device is used in the body. A sensor can also or alternatively be included on the elongate retractor shaft, for example on the blunt retraction tip, such that the sensor can monitor physiological parameters of the tissue in or adjacent to the surgical field.Type: GrantFiled: June 27, 2022Date of Patent: November 5, 2024Assignee: DePuy Synthes Products, Inc.Inventors: John Riley Hawkins, Nicholas Pavento, Sean P.

Publication number: 20240099805Abstract: A system for facilitating a medical procedure includes an access device that is configured to provide distance information regarding anatomical structures as the access device is driven to a target anatomical site. For instance, the access device can have either or both of a camera and neuromonitoring electrodes. The camera can send real-time images of the anatomical structures as the access device is driven toward the target anatomical site. The electrodes can emit an electrical current to identify a distance from nerve structure. A visual display can include the anatomical structure identified to the operator to assist in guiding the access device to the target anatomical site.Type: ApplicationFiled: September 26, 2022Publication date: March 28, 2024Inventors: Joern Richter, Thomas Gamache, John Riley Hawkins

Publication number: 20240016521Abstract: Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.Type: ApplicationFiled: July 21, 2023Publication date: January 18, 2024Inventors: Kevin Lee, Mark Hall, Christopher Ramsay, John Riley Hawkins, Albert Montello, Joseph Peterson, Benjamin Johnston, Heiko Koller, Todd Albert, Christopher Ames, Bradford Currier, Claudius Thorne, Masashi Neo

Patent number: 11844702Abstract: A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.Type: GrantFiled: June 28, 2021Date of Patent: December 19, 2023Assignee: DePuy Synthes Products, Inc.Inventors: Nicholas Pavento, John Riley Hawkins, Sheryl Furlan, Douglas Raymond

Patent number: 11766279Abstract: Devices and methods for enhancing the effectiveness of spinal stabilization, and particularly that of cervical spinal stabilization, are provided herein. More specifically, methods and systems are disclosed for effectively positioning occipital plates and spinal fixation assemblies within target vertebrae, while also reducing any associated patient trauma (e.g., muscle stripping, tissue damage, etc.). The systems and methods can utilize trans-lamina delivery of the spinal fixation assemblies to allow for the positioning of the fixation elements along the midline of the patient's spine.Type: GrantFiled: March 13, 2020Date of Patent: September 26, 2023Assignee: DePuy Synthes Products, Inc.Inventors: John Riley Hawkins, Thomas J.

Patent number: 11660149Abstract: Electronic devices that detect their position and/or orientation with respect to earth's frame of reference are described. A coupler can removeably maintain the electronic devices in physical proximity of one another. Each electronic device can have a housing and the coupler can be included on the housing and arranged to physically connect the housing of the electronic device to the housing of at least one other electronic device. Alternatively, the coupler can be a packaging that maintains the electronic devices in physical proximity of one another. Each electronic device can be calibrated using the orientation or position information obtained by other electronic devices maintained by the coupler. Further, each electronic device can include a power source that remains inactive until the device is ready for use.Type: GrantFiled: October 25, 2021Date of Patent: May 30, 2023Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: William Frasier, John Riley Hawkins, Roman Lomeli, Mark Hall, Dennis Chien

Patent number: 11638592Abstract: Disclosed herein are devices and methods for removing tissue. In one aspect, a device for removing tissue includes a hollow elongate member having an outer wall and a lumen, a selectively deployable tissue-cutting element extending from the hollow elongate member, and an actuation member extending through the lumen and coupled to the hollow elongate member at a location that is distal to the tissue-cutting element. Movement of the actuation member can cause the tissue-cutting element to move from the insertion configuration where the tissue-cutting element is not deployed to a tissue-cutting configuration where the tissue-cutting element is deployed such that it is radially extended relative to the insertion configuration.Type: GrantFiled: August 20, 2018Date of Patent: May 2, 2023Assignee: DePuy Synthes Products, Inc.Inventors: Shawn D.
