In this illustrative example, the unit has a unit sensory output (e.g., a speaker or a display), and the pads, and/or their associated packaging, have an ancillary sensory output (e.g. a speaker or display). Programming in the AED unit controls output to the sensory outputs such that the user's attention is directed between the unit and the ancillary components.Type: GrantFiled: January 5, 2010Date of Patent: July 16, 2013Inventors: Gintaras A Vaisnys, Glenn W. Laub, Giovanni C Meier

Patent number: 8483829Abstract: An external programming system for programming an implantable medical device includes a user display and a memory storing multiple intracardiac lead images. The intracardiac lead images correspond to lead types and includes electrodes spaced according to the spacing of electrodes of a particular lead type. The programmer selects one of the lead images for display based on an indication of which type of lead has been implanted in a patient. The selected image is displayed to a user as part of a graphical user interface for programming cardiac pacing therapy for the patient.Type: GrantFiled: September 20, 2012Date of Patent: July 9, 2013Assignee: Medtronic, Inc.Inventors: Marilyn C. Rochat, Arathi Sethumadhavan, Elizabeth A. Schotzko

Patent number: 8478418Abstract: A data collection system collects and stores physiological data from an ambulatory patient at a high resolution and/or a high data rate (“more detailed data”) and sends a low-resolution and/or downsampled version of the data (“less detailed data”) to a remote server via a wireless network. The server automatically analyzes the less detailed data to detect an anomaly. A two-tiered analysis is used, where the first tier is less specific than the second tier. If the less specific analysis detects or suspects the anomaly, the server signals the data collector to send more detailed data that corresponds to a time period associated with the anomaly. The more specific second tier analysis the more detailed data to verify the anomaly. The server may also store the received data and make it available to a user.Type: GrantFiled: April 13, 2012Date of Patent: July 2, 2013Assignee: InfoBionic, Inc.Inventor: Michael Fahey

Patent number: 8478408Abstract: Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.Type: GrantFiled: March 8, 2007Date of Patent: July 2, 2013Assignee: Boston Scientific Scimed Inc.Inventors: Roger N. Hastings, William J. Drassler, Daniel M. Lafontaine, Scott R. Smith, Anupama Sadasiva

Patent number: 8473066Abstract: By incorporating magnetic field sensing coils in an external charger, it is possible to determine the position of an implantable device by sensing the reflected magnetic field from the implant. In one embodiment, two or more field sensing coils are arranged to sense the reflected magnetic field. By comparing the relative reflected magnetic field strengths of the sensing coils, the position of the implant relative to the external charger can be determined. Audio and/or visual feedback can then be communicated to the patient to allow the patient to improve the alignment of the charger.Type: GrantFiled: July 6, 2009Date of Patent: June 25, 2013Assignee: Boston Scientific Neuromodulation CompanyInventors: Daniel Aghassian, Lev Freidin, Joey Chen

Patent number: 8467873Abstract: In a medical telemetry system for synchronizing an implantable medical device to a base station of the telemetry system, a communication channel is selected for communication between the implantable medical device and the base station, and the implantable medical device is synchronized to the base station by selecting a synchronizing word associated with the selected channel, wherein at least two different communication channels within the medical telemetry system are associated with different synchronization words. By this procedure, crosstalk is eliminated.Type: GrantFiled: September 27, 2007Date of Patent: June 18, 2013Assignee: St. Jude Medical, ABInventors: Pär Edlund, Johan Franzén

Patent number: 8463392Abstract: An external controller/charger system for an implantable medical device is disclosed, in which the external controller/charger system provides automatic switching between telemetry and charging without any manual intervention by the patient. The external controller/charger system includes an external controller which houses a telemetry coil and an external charging coil coupled to the external controller. Normally, a charging session is carried out using the external charging coil, and a telemetry session is carried out using the telemetry coil. However, when a patient requests to carry out telemetry during a charging session, the external charging coil is used instead of the internal telemetry coil.Type: GrantFiled: November 11, 2009Date of Patent: June 11, 2013Assignee: Boston Scientific Neuromodulation CorporationInventor: Daniel Aghassian
