Publication number: 20240157155Abstract: An implantable stimulator device is disclosed for executing a stimulation program comprising a plurality of sub-programs, wherein the sub-programs are configured to be automatically sequentially executed by stimulation circuitry in the device. Control circuitry periodically stores log data to indicate where each sub-program is in its execution. If the device experiences an interruption that prevents the stimulation circuitry from executing the stimulation program, and upon receiving an indication that the stimulation circuitry can continue execution of the stimulation program, the control circuitry is configured to query the log data to determine a sub-program during which the interruption occurred, and using the log data, cause the stimulation circuitry to continue execution of the stimulation circuitry either at the beginning of the sub-program, or at a point during the sub-program when the interruption occurred.Type: ApplicationFiled: January 23, 2024Publication date: May 16, 2024Inventors: Que Doan, Sridhar Kothandaraman, Adam Featherstone, Dennis Vansickle

Patent number: 11925810Abstract: A filtering algorithm implemented by a filtering module in an implantable medical device (IMD), or in an external device for communicating with an IMD, is disclosed which reviews blocks based on a number of rules. The filtering module preferably comprises both firewall and instruction analysis modules. The instruction analysis module analyzes the instructions and associated data (if present) in each block to determine whether such blocks would compromise operation of the IPG or injure a patient if executed. Instruction rules corresponding to an instruction identified in the block are retrieved by the instruction analysis module. The instruction analysis module reviews the block per the retrieved rules, and possibly also in light of current and historical IPG therapy setting or mode data, or other received but un-executed blocks. If a block is compliant, it is executed by the IMD or transmitted to the IMD.Type: GrantFiled: December 8, 2020Date of Patent: March 12, 2024Assignee: Boston Scientific Neuromodulation CorporationInventors: Sridhar Kothandaraman, Dennis Zottola

Publication number: 20240040649Abstract: An advertising algorithm is disclosed which operates in an Implantable Medical Device (IMD) to adjust an interval at which the IMD will transmit advertising data packets to an external device able to connect with the IMD. When a communication session between the IMD and an external device is terminated, the advertising algorithm will issue advertising data packets at a higher rate for a set duration. This will allow the external device to connect more quickly with the IMD in a next communication session. After the set duration, when it may be assumed that the external device is less likely to connect with the IMD, the algorithm reduces that rate at which advertising data packets are issued, which saves power in the IMD.Type: ApplicationFiled: October 9, 2023Publication date: February 1, 2024Inventors: Berj Doudian, Chirag Shah, Joshua Uyeda, Sridhar Kothandaraman, John Rivera, Damon Moazen
