Patent number: 8761895Abstract: A telemetry wake-up circuit is electrically disposed between a telemetry transceiver associated with an AIMD, and an RF tag. The RF tag may be remotely interrogated to generate a signal to which the telemetry wake-up circuit is responsive to switch the telemetry transceiver from a sleep mode to an active telemetry mode. In the sleep mode, the telemetry transceiver draws less than 25,000 nanoamperes from the AIMD, and preferably less than 500 nanoamperes.Type: GrantFiled: March 8, 2010Date of Patent: June 24, 2014Assignee: Greatbatch Ltd.Inventors: Robert A.

Patent number: 8761878Abstract: An implantable cardiac monitor upgradeable to an implantable pacemaker or an implantable cardiac resynchronization device allows the use of a single implantable medical device for monitoring cardiac conditions and later, if needed, for cardiac pacing. The implantable medical device includes a circuit that can be configured, by programming through an external programmer, to either the implantable cardiac monitor or the implantable pacemaker. The implantable medical device is first configured to and used as the implantable cardiac monitor for acquisition of physiological data indicative of a need for a pacing therapy if the pacing therapy is to follow, the implantable medical device is reconfigured from the implantable cardiac monitor to the implantable pacemaker, thus eliminating the need of using two implantable medical devices.Type: GrantFiled: April 18, 2012Date of Patent: June 24, 2014Assignee: Cardiac Pacemakers, Inc.Inventor: Richard S. Sanders

Patent number: 8757485Abstract: The present disclosure involves a medical system. The medical system includes a medical device configured to deliver a medical therapy to a patient, a clinician programmer configured to program the medical device, and a manufacturing database configured to store and maintain an electronic inventory of a plurality of types of medical devices. The clinician programmer is configured to acquire a visual representation of the medical device, generate an electronic ticket identifying the medical device based on the visual representation, and send the electronic ticket to the manufacturing database. The manufacturing database is configured to receive the electronic ticket from the clinician programmer and perform at least one of the following tasks in response to the received electronic ticket: updating the electronic inventory, analyzing a usage trend of the medical device, predicting a potential shortage of the medical device, and suggesting a production schedule for the medical device.Type: GrantFiled: September 5, 2012Date of Patent: June 24, 2014Assignee: Greatbatch Ltd.Inventors: Scott Drees, Norbert Kaula, Yohannes Iyassu

Patent number: 8755885Abstract: The invention relates to medical devices such as pacemakers, pulse generators, cardioverter-defibrillators and the like and more particularly relates to modular and reconfigurable medical system platforms and methods of designing, testing, controlling and implementing diverse therapies, diagnostics, physiologic sensors and related instrumentation using said medical system platforms. Methods, systems and devices provide a new design platform for implantable and external medical devices such as pacemakers, defibrillators, neurostimulators, heart monitors, etc. A real-time, highly flexible system of software and hardware modules enables both prototypes and products to respond to patient and customer needs with greater design and manufacturing efficiency. Certain embodiments integrate a general-purpose processor with interface circuitry to provide a standard platform for implementing new and conventional therapies with software models rather than custom circuitry.Type: GrantFiled: April 28, 2005Date of Patent: June 17, 2014Assignee: Medtronic, Inc.Inventors: D.

Publication number: 20140163636Abstract: A method and apparatus for treatment of hypertension and heart failure by increasing vagal tone and secretion of endogenous atrial hormones by excitory pacing of the heart atria. Atrial pacing is done during the ventricular refractory period resulting in atrial contraction against closed AV valves, and atrial contraction rate that is higher than the ventricular contraction rate. Pacing results in the increased atrial wall stress. An implantable device is used to monitor ECG and pace the atria in a nonphysiologic manner.Type: ApplicationFiled: August 2, 2013Publication date: June 12, 2014Applicant: BackBeat Medical, Inc.Inventors: Howard Levin, Mark Gelfand
