Patent number: 11235141Abstract: Disclosed are systems and methods for use of an inductive link for a communication channel in a transcutaneous energy transfer system. An example system may include a resonant circuit associated with an external primary, a power transistor connected to the resonant circuit and configured to drive the resonant circuit with a first time-varying electrical signal having a frequency, and a power driver connected to the power transistor that is configured to set the frequency of the first time-varying electrical signal to a resonant frequency to enable power transfer from the external primary to an implanted secondary. The example system may further include a communication driver operatively connected to the power transistor and configured to encode the first time-varying electrical signal with a data signal by modulating an attribute of the time-varying electrical signal as electrical power is transferred from the external primary to the implanted secondary.Type: GrantFiled: September 9, 2019Date of Patent: February 1, 2022Assignee: Minnetronix, Inc.Inventors: Lori Lucke, Vlad Bluvshtein, James Kurkowski, William Weiss

Patent number: 10898628Abstract: Present embodiments are directed to measuring and calculating parameters to control and monitor a power transfer in an implanted medical device. The medical device may be implanted in a subject and typically includes an artificial heart or ventricle assist device. The system measures parameters and uses the parameters to calculate a coupling coefficient for coils that transfer power between an external primary and an implanted secondary. The system uses the calculated coupling coefficient to estimate heat flux being generated in the system. Based on the level heat flux detected, the system may issue alerts to warn the subject or control actions to mitigate the effects of the heat flux.Type: GrantFiled: December 11, 2018Date of Patent: January 26, 2021Assignee: Minnetronix, Inc.Inventors: Vlad Bluvshtein, Lori Lucke
