Patent number: 11229796Abstract: A device and method are described for transmitting tissue conductance communication (TCC) signals. A device may be is configured to establish a transmission window by transmitting a TCC test signal at multiple time points over a transmission test period to a receiving device and detect at least one response to the transmitted TCC test signals performed by the receiving device. The IMD is configured to establish the transmission window based on the at least one detected response so that the transmission window is correlated to a time of relative increased transimpedance between a transmitting electrode vector and receiving electrode vector during the transmission test period.Type: GrantFiled: December 14, 2018Date of Patent: January 25, 2022Assignee: Medtronic Inc.Inventors: Yanzhu Zhao, Yong K. Cho, Michael D. Eggen, Wei Gan, Kathryn Hilpisch, Srikara V. Peelukhana, Darrell J. Swenson, Joshua J. Blauer

Patent number: 10143847Abstract: In some examples, this disclosure describes a method for identifying a position within a patient for a first implantable medical device (IMD) to be implanted to facilitate tissue conductive communication (TCC) between the first IMD and a second IMD implanted within the patient. In some examples, the method includes storing model data that associates patient parameter data and second IMD position data with first IMD positions based on TCC communication performance, receiving patient parameter data indicating one or more anatomical or physiological parameters of the patient, receiving second IMD position data, performing analysis by at least one of comparing the model data to the patient parameter data and the second IMD position data, performing real-time computer simulations, or a combination of comparing and performing simulations, and outputting to a user an indication of the position for the first IMD to be implanted within the patient based on the analysis.Type: GrantFiled: July 20, 2017Date of Patent: December 4, 2018Assignee: Medtronic, Inc.Inventors: Jonathan D.
