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: 20220117606Abstract: An assembly at a proximal end of an intravascular delivery system can allow the proximal end of a pull wire to move independently of a delivery tube. The assembly can generally include the pull wire, the delivery tube, a feature to prevent the proximal end of the pull wire from becoming inaccessible due to distal movement of the pull wire, and a feature to protect the proximal end of the pull wire from inadvertent, premature manipulation. When the intravascular delivery system is navigating tortuous vasculature, the proximal end of the pull wire can move distally in relation to the proximal end of delivery tube, relieving stress on the distal end of the pull wire. The proximal end of the pull wire can be protected from inadvertent manipulation during delivery and made available for manipulation once the distal end of the delivery system is in place.Type: ApplicationFiled: December 29, 2021Publication date: April 21, 2022Applicant: DePuy Synthes Products, Inc.Inventors: Tyson MONTIDORO, Juan LORENZO

Patent number: 11309764Abstract: Systems and apparatus for reliably sealing a surgical device are disclosed herein. Specifically, a surgical device including a drive shaft tube that is coupled to a drive shaft is disclosed. Because the drive shaft tube is coupled to the drive shaft, the drive shaft tube rotates at the same rotational speed as the drive shaft, which is less than the rotational speed of a cannulated motor shaft. The drive shaft tube can extend through the cannulated motor shaft. In addition, a sealing member can be provided to seal between the drive shaft tube (which rotates slowly) and the motor instead of between the motor shaft (which rotates more quickly) and the motor. The sealing member can be provided in a gap defined between an outer surface of a portion of the drive shaft tube extending beyond the cannulated motor shaft and the motor.Type: GrantFiled: April 13, 2020Date of Patent: April 19, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Urs Dürrenberger, Martin Münch, Nils Schmuckli

Patent number: 11304710Abstract: An orthopaedic surgical instrument includes a customized patient-specific surgical instrument having a body. The body has a bone-facing surface and an outer surface positioned opposite the bone-facing surface. The body includes a number of bone-contacting segments raised relative to the bone-facing surface. The bone-contacting segment include negative contours shaped to match corresponding positive contours of a patient's bone. The positive contours correspond to silhouette curves of a three-dimensional model of the patient's bone that correspond to contours of the patient's bone captured in images used to generate the model. The body further includes a number of surgical guides extending from the outer surface to the bone-contacting surface or the bone-facing surfaces. A method associated with the instrument is also disclosed.Type: GrantFiled: December 28, 2019Date of Patent: April 19, 2022Assignee: DePuy Synthes Products, Inc.Inventors: James M. Rhodes, R.

Patent number: 11305112Abstract: A bone implant kit includes an implant and first and second electrical stimulation anchors. The implant defines an inner surface inner configured to face a bone to which the bone implant kit is configured to attach, and an outer surface opposite the inner surface. The implant further defines first and second bone fixation holes that each extend from the inner surface to the outer surface. The first and second bone fixation holes are spaced from each other along a longitudinal direction. The first electrical stimulation anchor can be sized and configured for insertion into the first bone fixation hole, and the second electrical stimulation anchor can be sized and configured for insertion into the second bone fixation hole. The first and second electrical stimulation anchors can be configured to respond to a magnetic field so as to generate an electric field between the first and second electrical stimulated anchors.Type: GrantFiled: May 16, 2018Date of Patent: April 19, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Jochen Walser, Mario Gehri, Andre Furrer

Patent number: 11298233Abstract: A surgical procedure method includes accessing an implanted joint prosthesis having an implant engaged within a bone of the joint and a first articulating component mounted by a first mating component to a first insert component removably mounted to the implant, and partially disassembling the accessed implanted joint prosthesis by removing the first insert component with the first articulating component fixed thereto from the implant while the implant is engaged with the bone. The angular position of the first mating component with respect to the first insert component is then determined and replicated with a second insert component and a second mating component. The second insert component and the second mating component are then fixed at the replicated angle and the fixed second insert component and second mating component are mounted to the implant engaged within the bone. A new articulating component is then mounted to the second mating component.Type: GrantFiled: October 6, 2020Date of Patent: April 12, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Conrad Klotz, Jack Long

Patent number: 11291484Abstract: A bone plate system for internal fixation of bone fractures includes a bone plate having a plurality of bone plate holes. The holes are constructed to receive either a non-locking, locking, or variable-angle locking bone screw. The holes have discrete columns of teeth or thread segments arranged around the inner surface of the hole for engaging threads on the heads of locking and variable-angle locking bone screws. Conventional locking bone screws engage the bone plate coaxially with the central axis of the bone plate hole. Variable-angle locking bone screws can engage the bone plate at a selectable angle within a range of selectable angles relative to the central axis of the bone plate hole. The head of the variable-angle locking screw is at least partially spherical, and the thread thereon has a profile that follows the arc-shaped radius of curvature of the spherical portion of the screwhead.Type: GrantFiled: June 13, 2019Date of Patent: April 5, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Jason S.

Patent number: 11273050Abstract: An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.Type: GrantFiled: June 21, 2017Date of Patent: March 15, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Fausto Olmos, Brad S.
