Publication number: 20190000358Abstract: A method of initializing a sensor with a voltage sequence including a ramped voltage combined with a biphasic voltage pulse. The initialization scheme results in faster in-vitro sensor run-in and stabilization times. In various examples, the in-vitro sensor stabilization time is reduced from 200 minutes to 40-55 minutes (a reduction by a factor of least 5 as compared to a non-initialized sensor). In addition, staircase voltage initialization is implemented adaptively so that the voltage step size and sweep rates are changed depending on the state of the sensor (characterized by ISIG magnitude). As a result, individual sensors can be initialized in a customized manner rather than by using a general hardwired and harsh initialization scheme.Type: ApplicationFiled: June 30, 2017Publication date: January 3, 2019Applicant: Medtronic MiniMed, Inc.Inventor: Anuj M. Patel

Patent number: 10130767Abstract: An insulin infusion device includes a processor architecture, and a memory element that stores executable instructions to perform a method of controlling delivery of insulin to a user. The method operates the device in a closed-loop mode to deliver insulin, obtains patient-specific parameters for a current time sample, and estimates a plasma insulin value and a blood glucose value for the user based on at least some of the patient-specific parameters. The estimating is also based on a previously estimated plasma insulin value obtained for a previous time sample, and a previously estimated blood glucose value obtained for the previous time sample. A predicted sensor glucose value is generated for the current time sample, and the closed-loop mode or a safe basal mode is selected for controlling operation of the insulin infusion device in accordance with the selected mode.Type: GrantFiled: April 26, 2016Date of Patent: November 20, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Benyamin Grosman, Di Wu, Anirban Roy, Neha J.

Patent number: 10117992Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver fluid to a body of a user involves obtaining measurement values for a physiological condition influenced by the fluid, autonomously operating the infusion device to deliver the fluid based at least in part on the measurement values, and detecting a nonactionable condition based on the measurement values. In response to detecting the nonactionable condition, delivery of the fluid is limited while maintaining autonomous operation of the infusion device. In one exemplary embodiment, the nonactionable condition is a rescue condition indicative of the user having consumed fast-acting carbohydrates, and thus insulin delivery may be automatically limited in response to detecting the rescue carbohydrate consumption.Type: GrantFiled: April 11, 2016Date of Patent: November 6, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Neha J. Parikh, Anirban Roy, Benyamin Grosman, Rebecca K. Gottlieb, Di Wu
