Patent number: 11158413Abstract: A medical device system and related method of automatically adjusting parameters of an insulin delivery controller of an insulin infusion device are disclosed. The methodology obtains therapy-related data associated with operation of the insulin infusion device for a number of days in the past, including sensor glucose data associated with glucose levels of the user, and meal data associated with identified meals. The obtained therapy-related data is processed to generate a suitable pharmacokinetic/pharmacodynamic (PK/PD) model of the user, wherein the PK/PD model fits at least some of the sensor glucose data obtained for the user. The PK/PD model can be used to calculate at least one adjusted parameter of the insulin delivery controller, based on additional therapy-related data associated with further operation of the insulin infusion device. The insulin delivery controller can be instructed or controlled to adjust its settings in accordance with the model-calculated parameters.Type: GrantFiled: April 16, 2019Date of Patent: October 26, 2021Assignee: MEDTRONIC MINIMED, INC.Inventors: Benyamin Grosman, Di Wu, Louis J.

Publication number: 20210275742Abstract: A method of automatically initializing an analyte sensor for a user is disclosed here. A first analyte sensor is operated in a first measurement mode to generate first sensor signals indicative of an analyte level of the user. A second analyte sensor is deployed to measure the analyte level of the user, and is operated in an initialization mode, concurrently with operation of the first analyte sensor in the first measurement mode, to receive sensor configuration data generated by the first analyte sensor. During operation of the second analyte sensor in the initialization mode, the second analyte sensor is calibrated with at least some of the received sensor configuration data. After the calibrating, operation of the second analyte sensor is transitioned from the initialization mode to a second measurement mode during which the second analyte sensor generates second sensor signals indicative of the analyte level of the user.Type: ApplicationFiled: March 6, 2020Publication date: September 9, 2021Inventors: Erik Montero, David C.

Publication number: 20210228805Abstract: Medical devices and related systems and operating methods are provided. A method of operating an infusion device capable of delivering fluid influencing a physiological condition to a patient involves obtaining an event indication, such as a meal indication, determining an initial bolus amount based on the event indication, and determining predicted values for the physiological condition of the patient during a time window into the future based at least in part on the initial bolus amount. When the predicted values violate a threshold during the time window, the control system identifies an adjusted bolus amount that results in the predicted values for the physiological condition satisfying the threshold during the time window from within a search space defined by the initial bolus amount and operates an actuation arrangement of the infusion device to deliver the adjusted bolus amount of the fluid to the patient.Type: ApplicationFiled: April 15, 2021Publication date: July 29, 2021Inventors: Louis J.

Patent number: 11007370Abstract: A method is provided for establishing a communication session with an implantable medical device (“IMD”). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The advertisement period and the scan period of the protocol are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD.Type: GrantFiled: January 2, 2018Date of Patent: May 18, 2021Assignee: PACESETTER, INC.Inventors: Reza Shahandeh, Richard Williamson, Gabriel A.

Publication number: 20210093783Abstract: A method of controlling an insulin infusion device involves controlling the device to operate in an automatic basal insulin delivery mode, obtaining a blood glucose measurement for the user, and initiating a correction bolus procedure when: the measurement exceeds a correction bolus threshold value; and a maximum basal insulin infusion rate is reached during the automatic basal insulin delivery mode. The correction bolus procedure calculates an initial correction bolus amount, and scales the initial amount to obtain a final correction bolus amount, such that a predicted future blood glucose level resulting from simulated delivery of the final correction bolus amount exceeds a low blood glucose threshold level. The final amount is delivered to the user during operation in the automatic basal insulin delivery mode.Type: ApplicationFiled: December 15, 2020Publication date: April 1, 2021Inventors: Louis J.

Publication number: 20210060244Abstract: A method and system are provided for verifying whether a non-medical client device is operating correctly with a medical device controlled by the non-medical client device (NMCD) and causing a notification to be generated. In accordance with the method, an application at the non-medical client device monitors for occurrence of a trigger event and when a trigger event is detected, the application can perform one or more diagnostic checks to verify whether a medical control application at the NMCD is operating correctly. When the application determines that the one or more diagnostic checks have failed, the medical control application can attempt to initiate one or more remedial correction measures to restore the medical control application so that it is operating correctly. When the one or more remedial correction measures were unsuccessful, the application causes the notification to be generated via a user interface of the non-medical client device.Type: ApplicationFiled: August 28, 2019Publication date: March 4, 2021Inventors: Afshin Bazargan, Michael Ivey, Virgilio Macion, Ali Dianaty
