Patent number: 11770016Abstract: Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue during a charging session used to recharge the rechargeable power source. In one example, a temperature sensor may sense a temperature of an internal portion of a device, wherein the housing of the device is not directly thermally coupled to the temperature sensor. A temperature for the housing of the device may then be estimated based on the sensed temperature provided by the non-thermally coupled temperature sensor. A processor may then control charging of the rechargeable power source based on the determined temperature for the housing.Type: GrantFiled: April 2, 2021Date of Patent: September 26, 2023Assignee: Medtronic, Inc.Inventors: Kunal Paralikar, Elizabeth A. Fehrmann, Venkat R. Gaddam, Boysie R. Morgan, David P. Olson, Jadin C. Jackson

Patent number: 9622700Abstract: Techniques relate to operating a medical device by classifying a detected posture state of a patient. This classification may be performed by comparing the detected posture state of the patient to posture state definitions available within the system. Each definition may be described in terms of a parameter (e.g., vector) indicative of a direction in three-dimensional space. The posture state definitions may be calibrated by automatically estimating values for these parameters, thereby eliminating the need for the patient to assume each posture state during the calibration process to capture actual parameter values. According to another aspect, the estimated parameter values may be updated as the patient assumes various postures during a daily routine. For instance, estimated vectors initially used to calibrate the posture state definitions may be changed over time to more closely represent posture states the patient actually assumes, and to further adapt to changes in a patient's condition.Type: GrantFiled: October 1, 2015Date of Patent: April 18, 2017Assignee: Medtronic, Inc.Inventors: Rajeev M. Sahasrabudhe, Lynn A. Davenport, Jon P. Davis, Wende L. Dewing, Elizabeth A. Fehrmann, Steven M. Goetz, Shyam L. Gokaldas, Eric J. Panken
