Patent number: 11116557Abstract: An orthopedic locking screw arranged in a bore of an orthopedic implant enables easy removal of a broken locking screw out of the implant. The orthopedic locking screw for a cooperation with a thread in the orthopedic implant comprises a longitudinally extending shaft. The shaft comprises a thread pattern section extending at least partially along the shaft. The thread pattern section comprises a first thread with a first direction, which is a functional thread configured for the cooperation with the thread in the orthopedic implant. The thread pattern section further comprises a second thread with a second direction opposite to the first direction of the first thread. The second thread is superimposed on the first thread and intersects the first thread. An orthopedic locking system comprises the orthopedic locking screw and the orthopedic implant. The locking screw is manufactured by applying the thread pattern section to the longitudinally extending shaft.Type: GrantFiled: December 6, 2017Date of Patent: September 14, 2021Assignee: Stryker European Operations Holdings LLCInventors: Nils Zander, Manfred Wieland

Patent number: 11116558Abstract: A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.Type: GrantFiled: August 19, 2020Date of Patent: September 14, 2021Assignee: Treace Medical Concepts, Inc.Inventors: W. Bret Smith, Paul Dayton, Sean F. Scanlan, F. Barry Bays, Carlos Eduardo Gil, John T. Treace, Robert D. Santrock, Daniel J. Hatch, Joe W. Ferguson

Patent number: 11116559Abstract: A surgical instrument includes a first member that includes a first element engageable with an inner surface of a head of a bone fastener and a second element engageable with an outer surface of the head. The first member defines a first-member longitudinal axis and the bone fastener defines a bone-fastener longitudinal axis. A second member defines a second-member longitudinal axis and is movable relative to the first member and engageable with the second element to dispose the first element and the second element with the head in a co-axial, capture orientation. wherein the first-member, bone-fastener, and second-member longitudinal axes are aligned. Systems, spinal constructs, implants and methods are disclosed.Type: GrantFiled: February 19, 2018Date of Patent: September 14, 2021Assignee: Warsaw Orthopedic, Inc.Inventors: Alexander J. Rohlfing, Jason M. May, Dustin Bobbitt

Patent number: 11116560Abstract: A catheter is provided comprising a flexible heat transfer element provided on an outer surface of the catheter. The catheter further comprises a conduit arranged to supply an inflation fluid for inflating the flexible heat transfer element so as to form an inflated balloon, and a plurality of cooling elements arranged to cool the inflation fluid for inflating the balloon. Each cooling element comprises a first tube provided inside a second tube, wherein the first tube is substantially parallel to the second tube. The second tube is configured to receive a flow of a coolant for cooling the cooling element from the first tube.Type: GrantFiled: November 16, 2016Date of Patent: September 14, 2021Assignee: Cryotherapeutics GmbHInventors: Maurice Buchbinder, Stewart M.

Patent number: 11116561Abstract: Devices, agents, and associated methods for selective modulation of renal nerves by localized delivery of neural ablative substances are disclosed herein. One aspect of the present technology is directed to a method for delivering a neuromodulatory agent (e.g., capsaicin) via a catheter to a kidney of the patient. The neuromodulatory agent selectively neuromodulates afferent renal nerves in a patient compared efferent renal nerves of the patient. The method can also include removing the catheter from the patient after delivering the neuromodulatory agent to conclude the procedure.Type: GrantFiled: January 17, 2019Date of Patent: September 14, 2021Assignee: MEDTRONIC ARDIAN LUXEMBOURG S.A.R.L.Inventor: Robert J.

Patent number: 11116564Abstract: Methods for treating anxiety disorders and for reducing a risk associated with developing an anxiety disorder in patients via therapeutic renal neuromodulation and associated systems are disclosed herein. Sympathetic nerve activity can contribute to several cellular and physiological conditions associated with anxiety disorders as well as an increased risk of developing an anxiety disorder. One aspect of the present technology is directed to methods for improving a patient's calculated risk score corresponding to an anxiety disorder status in the patient. Other aspects are directed to reducing a likelihood of developing an anxiety disorder in patients presenting one or more anxiety disorder risk factors. Renal sympathetic nerve activity can be attenuated to improve a patient's anxiety disorder status or risk of developing an anxiety disorder. The attenuation can be achieved, for example, using an intravascularly positioned catheter carrying a therapeutic assembly configured to use, e.g.Type: GrantFiled: July 3, 2018Date of Patent: September 14, 2021Assignee: MEDTRONIC ARDIAN LUXEMBOURG S.A.R.L.Inventors: Gabriel Lazarus, Douglas Hettrick
