Patent number: 10016605Abstract: 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 IPG control through software on 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: December 8, 2016Date of Patent: July 10, 2018Assignee: GLOBUS MEDICAL, INC.Inventors: Saif Khalil, Raghavendra Angara, Miles Curtis, Christopher Biele, Daniel Fellmeth

Patent number: 9965656Abstract: One aspect of the invention provides a method for multi-nozzle biopolymer deposition of heterogeneous materials to create or modify a composite biopolymer multi-part three-dimensional assembly having at least one biomimetic and at least one non-biomimetic feature. The method includes: (a) utilizing a CAD environment to design and/or modify a composite multi-part assembly, thereby producing a CAD design; (b) converting the CAD design into a three-dimensional heterogeneous material and multi-part assembly model in a format suitable for three-dimensional, multi-nozzle printing, wherein the design comprises at least one biomimetic feature and at least one non-biomimetic feature; and (c) printing the composite assembly by simultaneously depositing the heterogeneous materials using multiple, different, specialized nozzles, wherein the simultaneous depositing includes direct deposition of cells.Type: GrantFiled: October 28, 2015Date of Patent: May 8, 2018Assignee: Drexel UniversityInventors: Wei Sun, Jae Hyun Nam, Andrew Leete Darling, Saif Khalil

Publication number: 20180123380Abstract: 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: ApplicationFiled: December 22, 2017Publication date: May 3, 2018Inventors: Raghavendra Angara, Saif Khalil, Miles Curtis, Christopher Biele, Daniel Fellmeth

Patent number: 9950174Abstract: An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body includes a timing generator and high frequency generator. The timing generator generates timing signals that represent stimulation signals for multiple channels. The high frequency generator determines whether to modulate the timing signals and modulates them at a burst frequency according to stored burst parameters if the decision is yes. As such, the IPG provides the ability to generate both the low frequency and high frequency stimulation signals in different channels according to user programming.Type: GrantFiled: July 6, 2017Date of Patent: April 24, 2018Assignee: GLOBUS MEDICAL, INC.Inventors: Christopher Biele, Raghavendra Angara, Saif Khalil

Publication number: 20180101861Abstract: 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: ApplicationFiled: December 13, 2017Publication date: April 12, 2018Inventors: Raghavendra Angara, Saif Khalil, Miles Curtis, Christopher Biele, Daniel Fellmeth

Patent number: 9878170Abstract: A wireless charger for inductively charging a rechargeable battery of an implantable pulse generator (IPG) is provided. The charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. The alignment circuit continuously detects a reflected impedance of the charging coil through a reflected impedance sensor, and controls a vibrator to output a tactile signal which is indicative of the alignment of the charging coil to the receiving coil based on the detected reflected impedance. Advantageously, the tactile feedback to the patient provides an optimal way to indicate the extent of the charger's alignment with the IPG.Type: GrantFiled: March 10, 2015Date of Patent: January 30, 2018Assignee: Globus Medical, Inc.Inventors: Raghavendra Angara, Saif Khalil, Miles Curtis, Christopher Biele, Daniel Fellmeth
