Patent number: 10886751Abstract: Various embodiments of a wireless connector system are described. The system has a transmitter module and a receiver module that are configured to wirelessly transmit electrical energy and/or data via near field magnetic coupling. The wireless connector system is designed to increase the amount of wirelessly transmitted electrical power over a greater separation distance. The system is configured with various sensing circuits that alert the system to the presence of the receiver module to begin transfer of electrical power as well as undesirable objects and increased temperature that could interfere with the operation of the system. The wireless connector system is a relatively small foot print that is designed to be surface mounted.Type: GrantFiled: August 25, 2017Date of Patent: January 5, 2021Assignee: NuCurrent, Inc.Inventors: Vinit Singh, Pavel Shostak, Alberto Peralta, Jason Luzinski, Jacob D.

Patent number: 10881420Abstract: Retrieval assemblies configured to capture an obstruction located in a bodily duct of a patient and associated methods of manufacture are provided. According to one implementation a retrieval assembly is provided that includes a distal collar fixed stationary on an elongate wire, a proximal collar slideable along a portion of the length of the elongate wire, and a plurality of shape memory elongate clot capturing elements that each has a proximal end coupled to the proximal collar and a distal end coupled to the distal collar. The retrieval device is configured to automatically transition from a radially constrained state to an expanded rest state with the proximal collar located nearer the distal collar when in the expanded rest state. As the retrieval device transitions from the radially constrained state to the expanded rest state, proximal portions of the clot capturing elements invert around the proximal collar.Type: GrantFiled: November 8, 2019Date of Patent: January 5, 2021Inventor: Timothy William Ingraham Clark

Patent number: 10861604Abstract: Presented are systems and methods that provide patients with diagnostic measurement tools and clear and concise audio/video guidance to reliably and accurately perform clinical grade diagnostic measurements of key vital signs. In various embodiments, this is accomplished by using an automated remote (or local, e.g., in the form of a kiosk) end-to-end medical diagnostic system that monitors equipment usage for accuracy. The diagnostic system analyzes patient responses, measurement data, and patient-related information to generate diagnostic and/or treatment information that may be shared with healthcare professionals and specialists, as needed. Automation provides for timely, hassle-free, and cost-effective health care management that takes the stress out of doctor visits, while delivering personalized health care. The high accuracy of generated diagnostic data improves health care to patients and reduces the risk of medical malpractice for treating physicians.Type: GrantFiled: November 4, 2016Date of Patent: December 8, 2020Assignee: AdviNow, Inc.Inventor: James Stewart Bates
