Publication number: 20130066201Abstract: An angiographic injector system and a method of controllably delivering medical fluid to a patient from an angiographic injector system are disclosed. A multiple processor control system is used to actively control the injection process and to monitor sensed functions of the system. The multiple processors provide dual redundancy safety circuits for critical control functions such as syringe motor drive speed and current. A motor/servo-amplifier nested control function is also disclosed. A unique method and apparatus are disclosed for establishing injection parameter default values just prior to an injection procedure that are based on physiological values of the patient to be treated. The injector system uses an interactive display panel that presents sequenced set-up screens to the user and which enables the user to select injection procedures, parameters and other modes of operation directly through the interactive panel.Type: ApplicationFiled: September 14, 2012Publication date: March 14, 2013Applicant: ACIST MEDICAL SYSTEMS, INC.Inventors: Douglas J. Duchon, James P. Smith, Katherine H. Anderson, Robert F. Wilson, Jiyan Liu

Patent number: 8369946Abstract: An implantable medical device and associated method classify therapy outcomes and heart rhythms in association with therapy outcome. A therapy success time interval is started in response to delivering an arrhythmia therapy. If normal sinus rhythm is detected after the therapy success time interval expires, the delivered therapy is classified as unsuccessful and the detected arrhythmia is classified as a self-terminating rhythm.Type: GrantFiled: September 16, 2008Date of Patent: February 5, 2013Assignee: Medtronic, Inc.Inventors: Anne M. Gillis, Katherine H. Anderson, Douglas A. Hettrick, David E. Ritscher

Patent number: 8290588Abstract: With a method and apparatus for detecting cardiac arrhythmias during overdrive pacing, a maximum paced rate and a reduced paced rate for a heart are determined, the maximum paced rate being higher than the reduced paced rate. The heart is paced at the maximum paced rate. After the heart is paced at the maximum paced rate for a predetermined amount of time, the heart is paced at the reduced paced rate.Type: GrantFiled: March 12, 2010Date of Patent: October 16, 2012Assignee: Medtronic, Inc.Inventors: Douglas A.

Publication number: 20110282225Abstract: A computing device includes a memory device, a communication module, an interface, a processor, a display controller, and an input device. The communication module wirelessly receives a stream of first electrogram waveforms (EGMs) from an implantable medical device (IMD). The interface receives a stream of second EGMs. The processor stores the first and second EGMs and retrieves the stored first and second EGMs. The display controller displays the first and second EGMs together when the first and second EGMs are received. The input device is configured to receive a selection command from a user. The processor retrieves a portion of at least one of the first and second stored EGMs in response to the selection command. The display controller displays the retrieved portion of the at least one of the first and second stored EGMs while the processor concurrently stores the streams of the first and second EGMs.Type: ApplicationFiled: May 12, 2010Publication date: November 17, 2011Applicant: Medtronic, Inc.Inventors: Katherine H.

Patent number: 7689279Abstract: A pacing control is used in a multiple-chamber cardiac pacing system, which, upon detecting an atrial arrhythmia, automatically switches to a special therapy mode and administers a selected anti-tachycardia pacing (ATP) therapy in the atrium, and which switches to a standard pacing mode following delivery of the ATP therapy. The pacing control adjusts the timing of pacing pulses to be delivered to the atrium and/or the ventricle to minimize any potential ventricular pauses that may result from the switch from the therapy mode to the standard pacing mode.Type: GrantFiled: November 10, 2005Date of Patent: March 30, 2010Assignee: Medtronic, Inc.Inventors: Paul D.

Patent number: 5919212Abstract: An automated external defibrillator automatically performs periodic self-tests on a daily and weekly basis. Self-test failures are identified by a watchdog timer which is reset upon activation of each periodic self-test. If the watchdog timer times out a maintenance indication is activated. The timeout period of the watchdog timer is non-repeating and non-periodic (typically 30 hrs.). Tested functions include the presence and interconnection of defibrillator electrodes, battery charge state, and the operability of the high voltage circuit. Visual and audible indicators are actuated to alert an operator if faults are identified. A record of each self-test is stored in memory, and can be subsequently retrieved through a communications port.Type: GrantFiled: November 26, 1997Date of Patent: July 6, 1999Assignee: SurVivaLink CorporationInventors: Kenneth F.
