Publication number: 20170106192Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients. A titration process is used to gradually increase the stimulation intensity to a desired therapeutic level. Between titration sessions one or more parameters, such as, for example, an acclimation interval, may be adjusted based on the patient's response to the stimulation. This personalized titration process can minimize the amount of time required to complete titration so as to begin delivery of the stimulation at therapeutically desirable levels.Type: ApplicationFiled: November 23, 2016Publication date: April 20, 2017Applicant: CYBERONICS, INC.Inventors: Imad Libbus, Bruce H. KenKnight, Badri Amurthur, Scott R. Stubbs

Publication number: 20170095669Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients. Stimulation from an implantable medical device (IMD) may be suspended in response to detecting a patient discomfort event, such as a cough, throat irritation, or voice alteration. The suspension period may be based on at least one of a severity level of the patient discomfort event and a patient physical state, such as being asleep or lying down. Detection of a patient discomfort event may be calibrated.Type: ApplicationFiled: October 4, 2016Publication date: April 6, 2017Applicant: CYBERONICS, INC.Inventors: Imad LIBBUS, Scott R.

Patent number: 9561378Abstract: Energy delivered from an implantable medical device to stimulate tissue within a patient's body is controlled. An electrical signal used to stimulate the tissue is changed from a first energy state to a second energy state during a magnetic resonance imaging (MRI) scan. The energy delivered is maintained at the second energy state after the MRI scan. A capture threshold of the tissue is then measured, and the energy delivered to the tissue is adjusted based on the measured capture threshold of the tissue.Type: GrantFiled: October 14, 2013Date of Patent: February 7, 2017Assignee: Cardiac Pacemakers, Inc.Inventors: Scott R. Stubbs, Kevin G. Wika

Patent number: 9381371Abstract: An implantable medical device (IMD) includes a lead having one or more sensing electrodes and one or more therapy delivery electrodes, and a sensor configured to detect the presence of static and time-varying scan fields in a magnetic resonance imaging (MRI) environment. A controller, in electrical communication with the lead and the sensor, is configured to process signals related to tachycardia events sensed via the one or more sensing electrodes and to deliver pacing and shock therapy signals via the one or more therapy delivery electrodes. The controller compares the sensed static and time-varying scan fields to static and time-varying scan field thresholds. The controller controls delivery of anti-tachycardia pacing and shock therapy signals as a function of the detected tachycardia events, the comparison of the sensed static scan field to the static scan field threshold, and the comparison of the time-varying scan fields to the time-varying scan field thresholds.Type: GrantFiled: October 20, 2013Date of Patent: July 5, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Scott R.

Patent number: 9037232Abstract: A system and method of enabling detection enhancements selected from a plurality of detection enhancements. In a system having a plurality of clinical rhythms, including a first clinical rhythm, where each of the detection enhancements is associated with the clinical rhythms, the first clinical rhythm is selected. The first clinical rhythm is associated with first and second detection enhancements. When the first clinical rhythm is selected, parameters of the first and second detection enhancements are set automatically. A determination is made as to whether changes are to be made to the parameters. If so, one or more of the parameters are modified under user control.Type: GrantFiled: August 11, 2014Date of Patent: May 19, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: James O.

Patent number: 9026213Abstract: A medical device lead includes a lead body having a proximal end and a distal end. The proximal end is configured for connection to a pulse generator. One or more electrodes are at a distal end of the lead body, and a lead conductor extends through the lead body and is electrically coupled to at least one of the one or more electrodes. The conductor is configured to deliver electrical signals between the proximal end and the at least one of the one or more electrodes. A sacrificial conductor extends through the lead body adjacent to lead conductor and is configured to fail at a lower stress than the lead conductor.Type: GrantFiled: July 13, 2012Date of Patent: May 5, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Arthur J. Foster, Christopher Perrey, Jeffrey E. Stahmann, Scott R. Stubbs

Patent number: 8977356Abstract: Systems and methods for arrhythmia therapy in MRI environments are disclosed. Various systems disclosed utilize ATP therapy rather than ventricular shocks when patients are subjected to electromagnetic fields in an MRI scanner bore and shock therapy is not available. As the patient is moved out from within the scanner bore and away from the MRI scanner, the magnetic fields diminish in strength eventually allowing a high voltage capacitor within the IMD to charge if necessary. The system may detect when the electromagnetic fields no longer interfere with the shock therapy and will transition the IMD back to a normal operational mode where shock therapy can be delivered. Then, if the arrhythmia still exists, the system will carry out all of the system's prescribed operations, including the delivery of electric shocks to treat the arrhythmia.Type: GrantFiled: January 23, 2014Date of Patent: March 10, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Scott R.

Patent number: 8653930Abstract: This document discusses, among other things, an inductive component that can include a core having two portions: (1) a first portion composed of a first material having a first magnetic saturation level; and (2) a second portion composed of a second material selected to provide inductance for the inductive component when an external magnetic field is greater than the first magnetic saturation level. In an example, the first portion can be composed of a material having a relatively low magnetic saturation level (e.g., a ferrite), and the second portion can be composed of a material having a relatively high magnetic saturation level (e.g., a high permeability iron alloy).Type: GrantFiled: February 18, 2013Date of Patent: February 18, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Jeffrey E.
