Publication number: 20100152795Abstract: Implantable stimulation devices can provide intracardiac electrograms (EGMs) and impedance measurements to detect changes in electrical, mechanical, and electromechanical activation of the heart. Many patients with congestive heart failure have conventional intracardiac devices implanted that are not capable of resynchronization therapy and these patients could benefit from resynchronization, but are not candidates based on current criteria. These patient populations can be identified through analyses of intracardiac electrogram data that is available through implantable stimulation devices comprising at least one lead for providing electrical stimulation to the heart of a patient, at least one sensor that detects electrical signals indicative of the depolarization of the heart of the patient, and a controller that is adapted to be implanted within the patient.Type: ApplicationFiled: December 11, 2008Publication date: June 17, 2010Applicant: PACESETTER, INC.Inventor: Stuart O.

Patent number: 7736312Abstract: An acoustic monitoring system that is able to verify the success or failure of the positional adjustment of a valve without the need for additional energy during non-invasive reprogramming is provided. The acoustic monitoring system includes a programmer for generating a sequence of commands to adjust the valve mechanism, and for receiving acoustic signals for analysis, a transmitter to implement the command and adjust the valve, and a sensor for detecting an acoustic signal generated from the valve during execution of the commands. A method for using the acoustic monitoring system is also provided.Type: GrantFiled: January 22, 2004Date of Patent: June 15, 2010Assignee: Codman & Shurtleff, Inc.Inventors: Terri K. Taylor, Meir Rosenberg, Rainuka Gupta, Stephen Ferrer Wilson, Pierre S. Ostiguy, Bertil Romner, Alan J. Dextradeur

Publication number: 20100137927Abstract: A pacemaker system 100 includes a pacemaker device 160, cardiac leads 120 and 150, guide catheter 110, an ultrasound transmitter 133 and an ultrasound receiver 130. Cardiac lead 150 is implanted in the right atrium (RA) 82 and includes an electrode 152 at its distal end that is actively fixed into location 102 of the right atrium 82. Electrode 152 is used for pacing of the RA. Cardiac lead 120 is implanted in the right ventricle (RV) 84 and includes two separate electrodes. A first electrode 140 is actively fixed into location 101 close to the apex 98 of the right ventricle 84 and is used for pacing, sensing and/or defibrillating of the RV. A second electrode 130 perforates the apex 98 of the right ventricle 84 and is actively fixed into the apex 99 of the left ventricle (LV) 86. Electrode 130 is used for pacing, sensing and/or defibrillating of the LV.Type: ApplicationFiled: December 1, 2009Publication date: June 3, 2010Inventor: TENGIZ TKEBUCHAVA

Publication number: 20100125174Abstract: Exemplary medical devices and systems for providing remote support relating to implantable medical devices (IMDS) are described. One method generates a graphical user-interface (GUI) relating to an IMD on a local medical device configured to interrogate the IMD. The method also recreates the GUI on a remote medical device effective that a cursor of the GUI can be manipulated from both the local medical device and the remote medical device while selection of IMD parameter values is available only at the local medical device.Type: ApplicationFiled: November 18, 2008Publication date: May 20, 2010Applicant: PACESETTER, INC.Inventors: Gregory C.

Patent number: 7720543Abstract: An implantable medical device (IMD) includes a telemetry module to communicate with an external device according to a given protocol. To establish a communication session, the IMD will extend active periods of reception on a given channel when some confirmed data is received from the external device. In addition, once a session has been opened, the programmer transmits a short data set (or preamble) for each cycle which the IMD is set to receive. This data set indicates whether additional data will or will not be sent. If no additional data is to be sent during that cycle, then the IMD powers down the receiver for that cycle.Type: GrantFiled: January 19, 2006Date of Patent: May 18, 2010Assignee: Medtronic, Inc.Inventors: Charles H. Dudding, Javaid Masoud
