Patent number: 7548788Abstract: An operating room connector is used in conjunction with a multiple electrode SCS system which can easily detach and connect to an external trial stimulator (ETS). By connecting the electrode SCS system to a stylet handle, and then locking the stylet handle within a slot of the connector platform, a user is able to minimize the required steps in connecting the ETS to the implanted SCS lead system. The ETS can then be used to readjust the position of the electrode array(s) previously implanted to deliver an optimal stimulation therapy.Type: GrantFiled: July 28, 2005Date of Patent: June 16, 2009Assignee: Boston Scientific Neuromodulation CorporationInventors: Kenny Kinyen Chinn, Carla Mann Woods, Stephen L Goldman

Publication number: 20090062883Abstract: A spinal cord stimulation (SCS) system includes multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) which channels can provide concurrent, but unique stimulation fields, permitting virtual electrodes to be realized. The SCS system includes a replenishable power source (e.g., rechargeable battery), that may be recharged using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery can be used to charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. An included bi-directional telemetry link in the system informs the patient or clinician the status of the system, including the state of charge of the IPG battery. Other processing circuitry in the IPG allows electrode impedance measurements to be made. Further circuitry in the external battery charger can provide alignment detection for the coil pairs.Type: ApplicationFiled: November 29, 2007Publication date: March 5, 2009Applicant: ADVANCED BIONICS CORPORATIONInventors: Paul M. Meadows, Carla Mann Woods, David K. Peterson, Joey Chen, David H. Payne

Patent number: 7450997Abstract: Leads and introduction tools are proposed for deep brain stimulation and other applications. Some embodiments of the present invention provide lead designs with which may be placed with a stylet, while others do not require a stylet. Some lead embodiments use standard wire conductors, while others use cable conductors. Several embodiments incorporate microelectrodes and/or microelectrode assemblies. Certain embodiments of the present invention provide introduction tools, such as cannula and/or cannula systems, which ensure proper placement of, e.g., leads.Type: GrantFiled: April 21, 2006Date of Patent: November 11, 2008Assignee: Boston Scientific Neuromodulation CorporationInventors: Anne M Pianca, Carla Mann Woods

Publication number: 20080221637Abstract: An implantable pulse generator includes a current steering capability that allows a clinician or patient to quickly determine a desired electrode stimulation pattern, including which electrodes of a group of electrodes within an electrode array should receive a stimulation current, including the amplitude, width and pulse repetition rate of such current. Movement of the selected group of electrodes is facilitated through the use of remotely generated directional signals, generated by a pointing device, such as a joystick. As movement of the selected group of electrodes occurs, current redistribution amongst the various electrode contacts takes place. The redistribution of stimulus amplitudes utilizes re-normalization of amplitudes so that the perceptual level remains fairly constant. This prevents the resulting paresthesia from falling below the perceptual threshold or above the comfort threshold.Type: ApplicationFiled: May 13, 2008Publication date: September 11, 2008Applicant: BOSTON SCIENTIFIC NEUROMODULATION CORPORATIONInventors: Carla Mann Woods, David K.L.

Patent number: 7295878Abstract: An implantable medical device, such as an implantable pulse generator (IPG) used with a spinal cord stimulation (SCS) system, includes a rechargeable lithium-ion battery having an anode electrode with a substrate made substantially from titanium. Such battery construction allows the rechargeable battery to be discharged down to zero volts without damage to the battery. The implantable medical device includes battery charging and protection circuitry that controls the charging of the battery so as to assure its reliable and safe operation. A multi-rate charge algorithm is employed that minimizes charging time while ensuring the battery cell is safely charged. Slow charging occurs at lower battery voltages (e.g., battery voltage below about 2.5 V), and fast charging occurs when the battery voltage has reached a safe level (e.g., above about 2.5 V). When potentially less-than-safe very low voltages are encountered (e.g., less than 2.Type: GrantFiled: October 22, 2004Date of Patent: November 13, 2007Assignees: Advanced Bionics Corporation, Quallion LLCInventors: Paul M Meadows, Carla Mann Woods, Joey Chen, Hisashi Tsukamoto

Patent number: 7239920Abstract: A neural stimulation system automatically corrects or adjusts the stimulus magnitude in order to maintain a comfortable and effective stimulation therapy. Auto correction of the stimulus magnitude is linked to the measurement of pressure in the vicinity of the electrode-tissue interface. Because the pressure near the electrode-tissue interface can provide a measure of the electrode contacts' proximity to the neural tissue, and hence quantity of electrical energy delivered to the neural tissue, a change in the measured pressure or pressure morphology indicates that the stimulation energy may need to be adjusted. Hence, changes in pressure provide a feedback mechanism that permit the system to effectively auto correct the stimulus amplitude in order to maintain a desired therapeutic effect.Type: GrantFiled: February 11, 2003Date of Patent: July 3, 2007Assignee: Advanced Bionics CorporationInventors: James R Thacker, Carla Mann Woods

Patent number: 7177690Abstract: A system and method for detecting the status of a rechargeable battery included within an implantable medical device. The medical device can incorporate a status indicator which signals the user concerning the battery status, e.g., low battery level. The signal may be audible or it may arise from an electrical stimulation that is perceptually distinguished from the operative, therapeutic stimulation. The external programmer may also incorporate a second battery status indicator that is visual, audible, or physically felt. Battery status data may be conveyed on visual displays on the external programmer by uploading this information from the medical device using a bi-directional telemetry link. Such battery status data are helpful to the user to indicate when the battery should be recharged and to the clinician to monitor patient compliance and to determine end-of-useful life of the rechargeable battery.Type: GrantFiled: January 31, 2003Date of Patent: February 13, 2007Assignee: Advanced Bionics CorporationInventors: Carla Mann Woods, James R Thacker, David K.

Publication number: 20030153959Abstract: A neural stimulation system automatically corrects or adjusts the stimulus magnitude in order to maintain a comfortable and effective stimulation therapy. Auto correction of the stimulus magnitude is linked to the measurement of coupling efficiency. Because the events that lead to the necessity of an output amplitude change are all associated with how much electrical energy is coupled to the neural tissue, and because there are several physiologic parameters that reflect in some measure how much energy is actually coupled to the tissue, the measurement of the one or more of such physiologic parameters is used as an indicator of the electrode's effectiveness in providing therapeutic stimulation.Type: ApplicationFiled: February 11, 2003Publication date: August 14, 2003Inventors: James R.
