Patent number: 11235143Abstract: A WCD system is configured to detect when a therapy administered to a patient by the WCD system is unsuccessful, and in response determine whether to send notifications to remote non-witness responders. The WCD system may be configured to decide to send such notifications after the WCD system determines it has administered a predetermined number of unsuccessful shocks to the patient. The predetermined number of unsuccessful shocks may be the maximum number of unsuccessful shocks the WCD system will administer to a patient, or every Xth shock (e.g., 3rd shock). The WCD system can be configured to periodically resend the notification. The notifications may be in form of SMS, voice messages, emails, app notifications, etc. sent to cell phones, smartphones, computers, laptops, tablets etc. of the responders either directly, via a server, or via a CAD-coupled server.Type: GrantFiled: November 10, 2017Date of Patent: February 1, 2022Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Douglas K. Medema, Steven E. Sjoquist

Publication number: 20200398065Abstract: “Artificial Intelligence” or “AI” technology can be applied to Wearable Cardioverter Defibrillators (“WCDs”) and other wearable medical equipment in various ways, including: garment fitting and adjustment; analyzing electrocardiogram (“ECG”), other sensor data and/or other patient data (e.g., age, gender, previous medical conditions, etc.) in real time to detect/assess the patient's present condition and/or need for treatment for cardiac and other conditions (e.g., stroke, coughing, apnea, etc.); detect imminent failure of the wearable medical device components capturing and reporting data collected from the patient for presenting to clinicians adjusting thresholds for alarms and notifications based on patient's responses; improving patient compliance based on the patient's past non-compliant behavior and actions that resulted in the patient becoming compliant; providing tests to the patient (e.g., grip test, dexterity tests, balance tests, etc.Type: ApplicationFiled: June 24, 2020Publication date: December 24, 2020Applicant: West Affum Holdings Corp.Inventors: Zoie R.

Publication number: 20200346026Abstract: In embodiments, a wearable medical system (WMS) for an ambulatory patient, which can be a wearable cardioverter defibrillator (WCD) system, analyzes the patient's ECG signal to generate a detection outcome. The WMS also has an ambulatory user interface that outputs a human-visible indication. A programming device, such as a PC, a tablet, etc., establishes a communication link with the WMS during an in-person session with the patient. The programming device may include a programming screen that reproduces the human-visible indication in real time. An advantage can be that the person programming the WMS need not strain to look also at the ambulatory user interface at the time they are looking at the programming device. Another advantage can be that the patient will recognize that he or she is better protected, and have their confidence in the WMS increased, and therefore better comply with wearing the WMS as required.Type: ApplicationFiled: July 22, 2020Publication date: November 5, 2020Inventors: David Peter Finch, Zoie Engman, Steven E. Sjoquist, Angela M. Stewart, Pamela Breske, Jonathan Paul Niegowski, Laura Marie Gustavson

Patent number: 5285792Abstract: A defibrillator/monitor (10) employing a message processing routine (60) that controls the way in which information from a plurality of sensing circuits (28) is communicated to an attending physician by output devices (30). In that regard, each of the various conditions monitored by the sensing circuits has a priority associated therewith. Each condition may be associated with one or more of five different types of messages: an initial display message, steady state display message, initial sound message, steady state sound message, and display icon message. The different messages, like the different conditions, may also be prioritized. The particular message or messages produced by the output devices in response to a particular set of conditions is then dependent upon the relative prioritization of the conditions and messages as evaluated by a microcomputer (18) in accordance with the routine.Type: GrantFiled: January 10, 1992Date of Patent: February 15, 1994Assignee: Physio-Control CorporationInventors: Steven E.

Patent number: 5247939Abstract: A defibrillator/monitor (10) employing a motion detection circuit 18 and control and processing circuit (20) that cooperatively detect motion at a patient-electrode interface. In that regard, an impedance measurement circuit (24) produces an output indicative of the impedance of the interface. This output is then processed by a number of filter elements before being analyzed by a motion detection routine (52). The motion detection routine includes subroutines (62 and 64) that compare the impedance against distinct upper and lower limits and then monitor the time at which the signal is above and below the limits. Basically, motion is indicated if the signal undergoes relatively large variations for a short time, or smaller variations for a longer time. A third motion clear subroutine (66) is used to determine when motion is no longer detected. Finally, a similar scheme (102) is employed to quickly restore the various filter elements after saturation.Type: GrantFiled: January 10, 1992Date of Patent: September 28, 1993Assignee: Physio-Control CorporationInventors: Steven E.
