Patent number: 11464991Abstract: In some embodiments, a wearable medical device system includes a processor configured to determine whether a patient requires electrical therapy to be provided via a plurality of therapy electrodes, the electrical therapy comprising discharging at least a portion of a stored electrical charge from an energy storage module, and if so, cause a fluid deploying mechanism to deploy a portion of the stored fluid to an interface between at least two therapy electrodes and the patient's skin prior to providing the electrical therapy, the deployed portion of fluid adapted to decrease the impedance measured by an impedance measurement circuit, and cause the fluid deploying mechanism to deploy an additional portion of fluid in response to the impedance measured by the impedance measurement circuit increasing above a threshold during the electrical therapy.Type: GrantFiled: December 17, 2019Date of Patent: October 11, 2022Assignee: West Affum Holdings Corp.Inventors: Daniel Ralph Piha, Joseph Leo Sullivan, Phillip Dewey Foshee, Jr., David Peter Finch, Isabelle Banville, Laura Marie Gustavson, Kenneth Frederick Cowan, Richard C.

Patent number: 11026578Abstract: Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patient's skin. A patient electrode includes a pad for attaching to the skin of a patient, a lead coupled to the pad, and a contact detector that can change state, when the pad does not contact fully the skin of the patient. When the detector changes state, an output device may emit an alert, for notifying a rescuer or even the patient.Type: GrantFiled: June 8, 2018Date of Patent: June 8, 2021Assignee: West Affum Holdings Corp.Inventors: Blaine Krusor, Isabelle Banville, Joseph Leo Sullivan, David Peter Finch, Daniel Ralph Piha, Laura Marie Gustavson, Kenneth Frederick Cowan, Richard C.

Patent number: 10507331Abstract: In embodiments, a wearable cardiac defibrillator system includes an energy storage module configured to store a charge. Two electrodes can be configured to be applied to respective locations of a patient. One or more reservoirs can store one or more conductive fluids. Respective fluid deploying mechanisms can be configured to cause the fluids to be released from one or more of the reservoirs, which decreases the impedance at the patient location, and decreases discomfort for the patient. In some embodiments an impedance is sensed between the two electrodes, and the stored charge is delivered when the sensed impedance meets a discharge condition. In some embodiments, different fluids are released for different patient treatments. In some embodiments, fluid release is controlled to be in at least two doses, with an intervening pause.Type: GrantFiled: January 9, 2018Date of Patent: December 17, 2019Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Daniel Ralph Piha, Joseph Leo Sullivan, Phillip Dewey Foshee, Jr., Daniel Peter Finch, Isabelle Banville, Laura Marie Gustavson, Kenneth Frederick Cowan, Richard C.

Patent number: 9987496Abstract: A wearable medical device includes a garment and a medical device. The medical device has a functionality that can transition between an operative state and an inoperative state. When the functionality is in the inoperative state, a protrusion extends so as to poke the patient, as an indication that steps need to be taken to make the device ready for use.Type: GrantFiled: August 8, 2017Date of Patent: June 5, 2018Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Joseph Leo Sullivan, Isabelle Banville, Blaine Krusor, Daniel Ralph Piha, Laura Marie Gustavson, David Peter Finch, Kenneth Frederick Cowan, Richard C.

Patent number: 9795782Abstract: RFID-based sensors, RFID readers and software sense a changed condition. In one embodiment, an RFID-based sensor includes a base that may be placed at a location where a condition may change. The sensor includes an RFID tag that is coupled to the base. The sensor also includes a detector that can be electrically coupled to the RFID tag. If the condition changes, an electrical property of the detector also changes, impacting an operation of the RFID tag. The impacted operation can be detected by an RFID reader/interrogator so as to provide a notification. An advantage over the prior art is that the condition change can be sensed wirelessly over a domain that can be laborious or hazardous to access otherwise. Moreover, RFID based sensors can be made by modifying common RFID tags.Type: GrantFiled: March 14, 2016Date of Patent: October 24, 2017Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Blaine Krusor, Isabelle Banville, Joseph Leo Sullivan, David Peter Finch, Daniel Ralph Piha, Laura Marie Gustavson, Kenneth Frederick Cowan, Richard C.

Patent number: 9757576Abstract: A portable medical device having a reliable readiness indicator. Embodiments provide a reliable readiness indicator with an active clasp that holds the garment in place. The clasp is enabled by the defibrillator when it is ready for use. If the clasp is not enabled the garment cannot be worn comfortably, and it becomes apparent to the patient that steps need to be taken to make the device ready for use.Type: GrantFiled: March 18, 2015Date of Patent: September 12, 2017Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Joseph Leo Sullivan, Isabelle Banville, Blaine Krusor, Daniel Ralph Piha, Laura Marie Gustavson, David Peter Finch, Kenneth Frederick Cowan, Richard C Nova
