Patent number: 11938303Abstract: Techniques disclosed herein relate to determining a calibrated measurement value indicative of a physiological condition of a patient using sensor calibration data and a performance model. In some embodiments, the techniques involve obtaining one or more electrical signals from a sensing element of a sensing arrangement, where the one or more electrical signals are influenced by a physiological condition in a body of a patient. The techniques also involve obtaining calibration data associated with the sensing element from a data storage element of the sensing arrangement, converting the one or more electrical signals into one or more calibrated measurement parameters using the calibration data, obtaining a performance model associated with the sensing element, obtaining personal data associated with the patient, and determining, using the performance model and based on the personal data and the one or more calibrated measurement parameters, a calibrated output value indicative of the physiological condition.Type: GrantFiled: December 14, 2022Date of Patent: March 26, 2024Assignee: MEDTRONIC MINIMED, INC.Inventors: Steven C. Jacks, Peter Ajemba, Akhil Srinivasan, Jacob E. Pananen, Sarkis Aroyan, Pablo Vazquez, Tri T. Dang, Ashley N. Sullivan, Raghavendhar Gautham

Patent number: 9848805Abstract: A new biostable glucose permeable polymer has been developed which is useful, for example, in implantable glucose sensors. This biostable glucose permeable polymer has a number of advantageous characteristics and, for example, does not undergo hydrolytic cleavage and degradation, thereby providing a composition that facilitates long term sensor stability in vivo. The versatile characteristics of this polymer allow it to be used in a variety of contexts, for example to form the body of an implantable glucose sensor. The invention includes the polymer composition, sensor systems formed from this polymer composition, and methods for making and using such sensor systems.Type: GrantFiled: December 18, 2015Date of Patent: December 26, 2017Assignee: Medtronic MiniMed, Inc.Inventors: Tri T.

Publication number: 20160354500Abstract: Medical devices are typically sterilized in processes used to manufacture such products and their sterilization by exposure to radiation is a common practice. Radiation has a number of advantages over other sterilization processes including a high penetrating ability, relatively low chemical reactivity, and instantaneous effects without the need to control temperature, pressure, vacuum, or humidity. Unfortunately, radiation sterilization can compromise the function of certain components of medical devices. For example, radiation sterilization can lead to loss of protein activity and/or lead to bleaching of various dye compounds. Embodiments of the invention provide methods and materials that can be used to protect medical devices from unwanted effects of radiation sterilization.Type: ApplicationFiled: June 2, 2015Publication date: December 8, 2016Applicant: Medtronic MiniMed, Inc.Inventors: Tri T.
