Patent number: 8718772Abstract: A system and method for temporary programming of an implantable medical device. The system and method include a repeater uploading temporary programming and instructions to a temporary memory of the device and then instructing the device to operate according to the temporary instructions. If during a first time period, the device is not in continuous periodic communication with the repeater, the device automatically reverts to operation under the normal operating instructions. At the end of the first time period, the caregiver or the patient may decide to revert to the normal programming. During a second time period, the device operates according to the temporary programming unless the caregiver or the patient instructs the device to revert to the normal programming, or the device fails to receive a periodic continuation signal from the repeater. Adverse health effects to the patient may also trigger the device to revert to the normal programming during either the first or second time period.Type: GrantFiled: November 26, 2008Date of Patent: May 6, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Kenneth P. Hoyme, Alan H. Smythe, Howard D. Simms, Jr., Conrad L. Sowder, David Ternes, Sylvia Quiles

Patent number: 8509910Abstract: This document discusses, among other things, an implantable device comprising a communication circuit configured to communicate with an external device, a logic circuit communicatively coupled to the communication circuit, and a processor, communicatively coupled to the logic circuit and the communication circuit. The processor is configured to communicate information with the external device, via the communication circuit and the logic circuit, using a set of communication messages. While in a device safety mode, the processor is held in an inactive state and the logic circuit is configured to communicate with the external device using a subset of the set of communication messages.Type: GrantFiled: December 4, 2008Date of Patent: August 13, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Conrad L. Sowder, Thomas J. Harris, Douglas J. Gifford, William J. Linder, Hiten J. Doshi, Scott R. Stubbs, Kenneth P. Hoyme

Patent number: 8364261Abstract: A pacing monitoring system is described for incorporation in an implantable pacemaker that monitors the pacing rate and/or cumulative pace count in order to protect a patient from excessive pacing. The system includes monitoring circuitry that is configured to operate in multiple monitoring zones, where each zone is adapted to prevent excessively high-rate pacing during a particular mode of device operation.Type: GrantFiled: November 1, 2010Date of Patent: January 29, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Scott Stubbs, Conrad L.

Patent number: 8347149Abstract: Embodiments herein generally relate to implantable medical devices and, specifically, to a system and method for providing fault tolerant processing in an implantable medical device. In an embodiment a system for providing fault tolerant processing in an implantable medical device is provided. The system can include an implantable medical device comprising a processor and memory store configured to execute a plurality of threads, temporal and spatial constraints assigned to one or more of the threads, and a kernel. The kernel can include a scheduler and a thread monitor configured to monitor execution of threads against the temporal and spatial constraints, and further configured to issue a response upon violation of either of the constraints by one of the plurality of threads. In an embodiment a method for providing fault tolerant processing in an implantable medical device is provided. Other embodiments are also included herein.Type: GrantFiled: September 28, 2009Date of Patent: January 1, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Scott R. Stubbs, Conrad L.

Patent number: 8170670Abstract: A system and method is disclosed for system fault recovery by an implantable medical device which employs a global fault response. The system enables the device to consistently recover from transient faults while maintaining a history of the reason for the device fault. Upon detection of a fault, the primary controller of the device signals a reset controller which then issues a reset command. All sub-systems of the primary device controller are then reset together rather than resetting individual sub-systems independently to ensure deterministic behavior.Type: GrantFiled: January 26, 2009Date of Patent: May 1, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Scott R.

Patent number: 7373200Abstract: A system and method is disclosed by which an implantable cardiac device may deliver tachyarrhythmia therapy in the event of a system fault. A hardware-based safety core provides the logic circuitry for detecting tachyarrhythmias and delivering shock therapy in the event of a fault which disables operation of the device's primary control circuitry. The safety core defibrillator eliminates common mode failure of the primary control circuits used in the primary defibrillator system. Failures in the primary controller memory or execution will activate the safety core defibrillator.Type: GrantFiled: May 5, 2005Date of Patent: May 13, 2008Assignee: Cardiac Pacemakers, Inc.Inventors: Scott Stubbs, Conrad L.
