Patent number: 9839783Abstract: Magnetic field detectors include a proof mass suspended by deformable arms similar to a three dimensional accelerometer. The magnetic field detectors further include magnetically sensitive material present on the proof mass and/or deformable arms to cause movement of the proof mass and/or deformable arms when in the presence of a magnetic field. This movement is converted to an electrical signal and that electrical signal is compared to a reference to determine if a magnetic field of interest is present. The magnetic field detector may be included within an implantable medical device, and when the magnetic field detector indicates that a magnetic field of an MRI scanner is present, the implantable medical device may switch to an MRI mode of operation. The device may also switch back to a normal mode of operation once the MRI scanner is no longer detected such as after a predefined amount of time.Type: GrantFiled: July 25, 2014Date of Patent: December 12, 2017Assignee: Medtronic, Inc.Inventors: Randal C.

Patent number: 8543190Abstract: A device includes a flexible substrate, N coiled conductors, and a plurality of folding regions. The N coiled conductors are deposited on the flexible substrate and connected in series by conductive interconnects. N is greater than 1. Each of the folding regions is defined by a separation distance between adjacent ones of the N coiled conductors. The conductive interconnects traverse the folding regions between the N coiled conductors to connect the N coiled conductors in series. The flexible substrate is folded such that the N coiled conductors form a stack of N coiled conductors.Type: GrantFiled: July 30, 2010Date of Patent: September 24, 2013Assignee: Medtronic, Inc.Inventors: James R.

Patent number: 8160834Abstract: The invention disclosed herein provides methods and materials for observing the state of a sensor, for example those used by diabetic patients to monitor blood glucose levels. Typically a voltage such as a voltage pulse is applied to the sensor in order to solicit a current response from which for example, factors such as impedance values can be derived. Such values can then be used as indicators of a sensor's state, for example the state of sensor hydration, sensor noise, sensor offset, sensor drift or the like.Type: GrantFiled: June 2, 2011Date of Patent: April 17, 2012Assignee: Medtronic MiniMed, Inc.Inventors: Bradley Chi Liang, Larry E.
