Patent number: 11704688Abstract: A wireless charger system for inductively charging a rechargeable battery of an implantable pulse generator (IPG) implanted in a human body is provided. A charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An end-of-charge (EOC) circuit continuously monitors the reflected impedance from a reflected impedance sensor and determines the end of charge when a predetermined pattern of the reflected impedance corresponding to an EOC signal from the IPG is received. Advantageously, receiving the EOC signal through the charging coil eliminates the need to provide a separate communication circuit in the IPG that communicates with the charger.Type: GrantFiled: October 16, 2020Date of Patent: July 18, 2023Assignee: Cirtec Medical Corp.Inventors: Raghavendra Angara, Saif Khalil, Miles Curtis, Christopher Biele, Daniel Fellmeth

Patent number: 11590351Abstract: Spinal cord stimulation (SCS) system having a recharging system with self alignment, a system for mapping current fields using a completely wireless system, multiple independent electrode stimulation outsource, and control through software on a Smartphone/mobile device and tablet hardware during trial and permanent implants. SCS system can include multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) providing concurrent, but unique stimulation fields. SCS system can include a replenishable power source, rechargeable using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery, can charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. A bi-directional telemetry link informs the patient or clinician the status of the system, including the state of charge of the IPG battery.Type: GrantFiled: April 22, 2019Date of Patent: February 28, 2023Assignee: CIRTEC MEDICAL CORPORATIONInventors: Saif Khalil, Raghavendra Angara, Miles Curtis, Christopher Biele, Daniel Fellmeth

Patent number: 11260230Abstract: An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body has a programmable signal generator that can generate the signals based on stored signal parameters without any intervention from a processor that controls the overall operation of the IPG. While the signal generator is generating the signals the processor can be in a standby mode to substantially save battery power. The IPG also contains circuity to indicate to a patient that proper alignment exists between the IPG and an external charger to charge a battery in the IPG.Type: GrantFiled: September 17, 2019Date of Patent: March 1, 2022Assignee: Cirtec Medical CorporationInventors: Saif Khalil, Raghavendra Angara, Miles Curtis, Christopher Biele, Daniel Fellmeth, Hrishikesh Gadagkar

Patent number: 11005305Abstract: A wireless charger for automatically tuning an optimum frequency to inductively charge a rechargeable battery of an implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body is provided. The charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An optimization circuit detects a reflected impedance of the charging coil through a reflected impedance sensor, and select an optimum frequency of a charging signal supplied to the charging coil based on the detected reflected impedances of a plurality of charging frequencies in a selected frequency range. Advantageously, the optimum charging frequency provides a more efficient way to charge the IPG's rechargeable battery.Type: GrantFiled: February 4, 2019Date of Patent: May 11, 2021Assignee: CIRTEC MEDICAL CORP.Inventors: Raghavendra Angara, Saif Khalil, Miles Curtis, Christopher Biele, Daniel Fellmeth
