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

Publication number: 20080243201Abstract: A combination pacer/defibrillator is tailored for bradycardia patients. In one example, its shock-delivery specificity exceeds its sensitivity to shockable ventricular tachyarrhythmias. In another example, its specificity exceeds 95%, or 99%, or even 99.5%. Sensitivity is programmed to a high desired sensitivity value, but only if it can be done without decreasing the specificity below the desired specificity threshold value. This can be conceptualized as “avoiding at all costs” delivering false shocks, even at the expense of failing to deliver a shock to a treatable ventricular tachyarrhythmia. Specificity enhancements include, among other things, inhibiting shock delivery when the patient is breathing or not supine, using multiple channels or a high rate VT/VF detection threshold.Type: ApplicationFiled: June 9, 2008Publication date: October 2, 2008Applicant: Cardiac Pacemakers, Inc.Inventors: Joseph M. Bocek, Richard M. Dujmovic, Phil Foshee, Harley White, Jaeho Kim, Anthony Harrington, Richard S. Sanders, Douglas R. Daum, Paul De Coriolis, Joseph Smith, Richard Fogoros

Patent number: 7050853Abstract: An implantable cardiac rhythm management device is programmed and configured to detect a death event. When such an event is detected, the device ceases recording of physiological data, thus preserving in the device's memory the data collected at and shortly before the time of death. A death event may be detected by detecting of an absence of intrinsic electrical activity in the patient's heart and a lack of an evoked response to a predetermined number of pacing pulses.Type: GrantFiled: July 7, 2003Date of Patent: May 23, 2006Assignee: Cardiac Pacemakers, Inc.Inventors: Geng Zhang, Richard S.

Patent number: 6955640Abstract: An apparatus and method for brachytherapy. One method includes locating a region of cardiac tissue having a relatively large probability of originating or transmitting electrical signals which result in arrhythmic activity and irradiating the region of cardiac tissue to reduce the amount of arrhythmic activity. Irradiating can include regulating protein expression of myocardial cells, killing myocardial cells, ablating myocardial cells, irradiating sleeves of atrial muscle that extend from a left atrial wall around the pulmonary veins, and/or creating lesions that block electrical conduction through myocardial tissue. Locating the region can include locating a foci of an atrial arrhythmia or locating the foci adjacent a pulmonary vein.Type: GrantFiled: September 28, 2001Date of Patent: October 18, 2005Assignee: Cardiac Pacemakers, Inc.Inventors: Richard S.

Patent number: 6952611Abstract: A method for assessing cardiac function suitable for incorporation into an implantable cardiac rhythm management device. By measuring daily exertion levels in accordance with the invention, an assessment of cardiac function can be made that has been found to correlate well with conventional clinical classifications. The invention also provides for assessing cardiac function in conjunction with different pacing schemes designed to treat heart failure and using the assessment to select the best such scheme for the patient.Type: GrantFiled: April 30, 2002Date of Patent: October 4, 2005Assignee: Cardiac Pacemakers, Inc.Inventors: Weimin Sun, Veerichetty Kadhiresan, Bruce H.

Publication number: 20040215240Abstract: A reconfigurable cardiac device includes a housing, and detection circuitry and energy delivery circuitry provided in the housing. One or more subcutaneous, non-intrathoracic electrodes are coupled to the energy delivery and detection circuitry. A lead interface is provided on the housing and coupled to the energy delivery and detection circuitry. The lead interface is configured to receive at least one lead that includes one or more intrathoracic lead electrodes. A controller is provided in the housing and coupled to the lead interface and the energy delivery and detection circuitry. The system is operable in a first configuration using the subcutaneous electrodes in the absence of the lead and operable in a second configuration using at least one or more of the lead electrodes. The system is capable of providing cardiac activity sensing and stimulation in each of the first and second system configurations, respectively.Type: ApplicationFiled: April 8, 2004Publication date: October 28, 2004Inventors: Eric G.

Patent number: 5609615Abstract: A cardiac simulator including a patient warning apparatus, having an electrically conductive suture point in electrical communication with the patient warning apparatus. An electrically conductive suture passed through the suture point connects said stimulator mechanically and electrically to excitable tissue such as skeletal tissue. Inside the suture point is a connection for assuring a reliable electrical contact between the suture point and the suture. The cardiac stimulator automatically alters the peak voltage of its output stimulus whenever a condition exists requiring patient notification or warning. A specialized shunt circuit mounted within the stimulator or in the header of the stimulator re-directs electrical current from the standard stimulation electrode to the electrically conductive suture point. A controlled switch may be mounted within a hermetically sealed can of the stimulator to re-direct a stimulation pulse to the suture point. The controlled switch could also be mounted in the header.Type: GrantFiled: September 22, 1995Date of Patent: March 11, 1997Assignee: Intermedics, Inc.Inventors: Richard S. Sanders, Patrick J.
