Patent number: 11932497Abstract: A method of inverting workpieces in a mass production process includes: advancing an end effector in electronic synchronization with advancement of a carrier to synchronize arrival of the carrier at a stop position with arrival of the end effector at an unloading position, in which the end effector is in alignment with a workpiece held by the carrier for engaging the workpiece; while the end effector is in engagement with the workpiece, retracting the end effector away from the carrier to unload the workpiece from the carrier and advancing the end effector back toward the carrier to load the workpiece back into the carrier; and rotating the end effector relative to the carrier to invert the workpiece in electronic synchronization with the retracting and advancing of the end effector for loading the workpiece back into the carrier when inverted.Type: GrantFiled: March 17, 2022Date of Patent: March 19, 2024Assignee: ATS CORPORATIONInventors: Kenneth Wayne Nicholson, Philip David Munroe, James Mark McLean, Robert James MacGregor, David Andrew Tait, Gustavo Barea, Roger Craig Hogan

Publication number: 20200352439Abstract: Provided are a localization system and method useful in the acquisition and analysis of cardiac information. The localization system and method can be used with systems that perform cardiac mapping, diagnosis and treatment of cardiac abnormalities, as examples, and in the retrieval, processing, and interpretation of such types of information. The localization system and method use high impedance inputs, improved isolation, and relatively high drive currents for pairs of electrodes used to establish a multi-axis coordinate system. The axes can be rotated and scaled to improve localization.Type: ApplicationFiled: April 15, 2020Publication date: November 12, 2020Inventors: Daniel J. Welsh, Marcus F. Julian, Graydon E. Beatty, Xinwei Shi, Derrick R. Chou, Randell L. Werneth, J. Christopher Flaherty, Mark MacGregor

Patent number: 10729891Abstract: Disclosed are devices, systems, and methods for providing access to a patient. The patient access device comprises a proximal end, a distal end and a lumen therethrough. The patient access device further comprises a hollow shaft, an input port and a liquid supply port. At least a portion of the lumen passes through the shaft. The input port is coupled to the lumen, and the lumen and the input port are constructed and arranged to receive an elongate probe. The liquid supply port is in fluid communication with the lumen. The patient access is constructed and arranged to reduce gas from exiting the distal end while a portion of the elongate probe is positioned in the patient access device.Type: GrantFiled: August 24, 2018Date of Patent: August 4, 2020Assignee: ACUTUS MEDICAL, INC.Inventors: Randell L. Werneth, David Zarbatany, Mark MacGregor, Ricardo David Roman, R. Maxwell Flaherty, J. Christopher Flaherty

Publication number: 20160354010Abstract: A system for determining a position of a medical device within a body is provided that reduces positional error by establishing a reference origin closer to the device and/or simplifies the system by integrating components and functions. In one embodiment, a pair of drive electrodes are affixed to opposed surfaces of the body and create a pathway for transmission of current through a position sensor related to the medical device. A pair of reference electrodes proximate the drive electrodes are coupled to a common reference node outputting a reference signal establishing the reference origin. An electronic control unit determines the position of the medical device responsive to the position signal and the reference signal. In another embodiment, a patch affixed to an external surface of the body has a base layer and multiple devices supported on the base layer, electrically isolated from one another, and configured to perform different functions.Type: ApplicationFiled: June 23, 2016Publication date: December 8, 2016Inventors: John A.
