Patent number: 8348923Abstract: An infusion system, which may be a closed loop, or “semi-closed-loop”, infusion system, uses state variable feedback to control the rate at which fluid is infused into a user's body. The closed loop system includes a sensor system, a controller, and a delivery system. The “semi-closed-loop” system further includes prompts that provide indications to the user prior to fluid delivery. The sensor system includes a sensor for monitoring a condition of the user and produces a sensor signal which is representative of the user's condition. The delivery system infuses a fluid into the user at a rate dictated by the commands from the controller. The system may use three state variables, e.g., subcutaneous insulin concentration, plasma insulin concentration, and insulin effect, and corresponding gains, to calculate an additional amount of fluid to be infused with a bolus and to be removed from the basal delivery of the fluid.Type: GrantFiled: August 12, 2010Date of Patent: January 8, 2013Assignee: Medtronic Minimed, Inc.Inventors: Sami S. Kanderian, Jr., Garry M. Steil

Publication number: 20120259278Abstract: An infusion system is for infusing a fluid into the body of a patient. The infusion system includes at least one sensor for monitoring blood glucose concentration of the patient and an infusion device for delivering fluid to the patient. The sensor produces at least one sensor signal input. The infusion device uses the at least one sensor signal input and a derivative predicted algorithm to determine future blood glucose levels. The infusion device delivers fluid to the patient when future blood glucose levels are in a patient's target range. The infusion device is capable of suspending and resuming fluid delivery based on future blood glucose levels and a patient's low shutoff threshold. The infusion device suspends fluid delivery when future blood glucose levels falls below the low shutoff threshold. The infusion device resumes fluid delivery when a future blood glucose level is above the low shutoff threshold.Type: ApplicationFiled: June 21, 2012Publication date: October 11, 2012Applicant: MEDTRONIC MINIMED, INC.Inventors: Andrew C.

Publication number: 20110282321Abstract: A system and method for controlling and monitoring a diabetes-management system through the use of a model that predicts or estimates future dynamic states of glucose and insulin from variables such as insulin delivery or exogenous glucose appearance as well as inherent physiological parameters. The model predictive estimator can be used as an insulin bolus advisor to give an apriori estimate of postprandial glucose for a given insulin delivery profile administered with a known meal to optimize insulin delivery; as a supervisor to monitor the operation of the diabetes-management system; and as a model predictive controller to optimize the automated delivery of insulin into a user's body to achieve a desired blood glucose profile or concentration. Open loop, closed-loop, and semi-closed loop embodiments of the invention utilize a mathematical metabolic model that includes a Minimal Model, a Pump Delivery to Plasma Insulin Model, and a Meal Appearance Rate Model.Type: ApplicationFiled: June 27, 2011Publication date: November 17, 2011Applicant: MEDTRONIC MINIMED, INC.Inventors: GARRY M.

Publication number: 20080097289Abstract: An algorithm and method of making intelligent therapy recommendations for insulin pump parameters is described. The pump parameters include basal rates, carbohydrate-to-insulin ratios (CIR), and insulin sensitivity factors (ISF). A determination of whether a therapy recommendation should be made is based on comparing an updated recommended change with a threshold. The updated recommended change to the pump parameter is made based on a previous recommended change to the pump parameter and the difference between a current blood glucose value and a targeted blood glucose level. The algorithm and method confirms the therapy recommendation is within safety parameters before displaying the therapy recommendation.Type: ApplicationFiled: September 6, 2006Publication date: April 24, 2008Applicant: MEDTRONIC MINIMED, INC.Inventors: Garry M.
