Patent number: 11723738Abstract: A small diameter surgical tool implements an agonist-antagonist deflectable joint. The deflectable joint is an actuatable bendable structure that uses push-pull, agonist-antagonist action of a pair of nested tubes to actuate the joint. The tubes are designed to have non-central, offset neutral axes, and they are fixed together at locations distal to the deflectable joint, such as at their distal ends. Axial translations of the tubes relative to each other causes a push-pull, agonist-antagonist action between the tubes, which causes the deflectable joint to bend. In one implementation, a deflectable joint can be created in nested tubes by configuring radial portions of the tube sidewalls extending along the joint to have an axial region of reduced stiffness. As a result, axial agonist-antagonist motion between the tubes can cause bending of the deflectable joint.Type: GrantFiled: November 6, 2017Date of Patent: August 15, 2023Assignees: UNIVERSITY OF TENNESSEE RESEARCH FOUNDATION, VANDERBILT UNIVERSITYInventors: Katherine E. Riojas, Robert J. Webster, Daniel Caleb Rucker, Kaitlin Oliver Butler, Ryan Ponten

Patent number: 11724111Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.Type: GrantFiled: April 19, 2021Date of Patent: August 15, 2023Assignee: Medtronic, Inc.Inventors: Hyun J.
