US Classification:

607 60, 6048901, 6048911, 607 32
Abstract:

A method of preventing inadvertent signal transmission sent from a remote control for controlling the operation of an implantable infusion device. The method includes maintaining the remote control in a locked state prior to a user intentionally unlocking the remote control in order to generate transmission of a signal from the remote control to the implantable infusion device. The unlocking of the remote control can include moving a button control element, unlocking a button lock, pressing a button other than the signal generation button, pressing the signal generation button in a specific sequence or shaking the remote control.

Variable Atrail Blanking Period In An Implantable Medical Device
view source
US Patent:

57358818, Apr 7, 1998
Filed:

Apr 14, 1997
Appl. No.:

8/843225
Inventors:

Andre Routh - Lake Jackson TX
Annette Bruls - Brussels, BE
Craig Housworth - Lake Jackson TX
Joseph Vandegriff - Brazoria TX
Yves Verboven - Kessel-lo, BE
Assignee:

Sulzer Intermedics Inc. - Angleton TX
International Classification:

A61N 1365
US Classification:

607 14
Abstract:

An implantable medical device for electrically stimulating the heart to beat including a pulse generator, a logic and control unit, and an atrial sense circuit. The atrial sense circuit processes signals from electrodes implanted in an atrial chamber of the heart. The atrial sense circuit provides an atrial sense signal to the logic and control unit when the magnitude of electrical activity in the atria exceeds a threshold. The medical device preferably paces the ventricles in response to detected electrical activity in the atria indicative of atrial contraction. Immediately following ventricular pacing, the medical device initiates an absolute atrial blanking period followed by an atrial sensing period and a programmable blanking period. During both the absolute atrial blanking period and the programmable blanking period, atrial sensing is disabled, while during the atrial sense period, atrial sensing is enabled. The time durations of the atrial sensing period and the programmable blanking period are programmable and may be programmed noninvasively while the medical device is implanted.

US Patent:

58431330, Dec 1, 1998
Filed:

Apr 14, 1997
Appl. No.:

8/843236
Inventors:

Andre Routh - Lake Jackson TX
Annette Bruls - Brussels, BE
Drury Woodson - Alvin TX
Joseph Vandegriff - Brazoria TX
Yves Verboven - Kessel-lo, BE
Assignee:

Sulzer Intermedics Inc. - Angleton TX
International Classification:

A61N 118
US Classification:

607 14
Abstract:

An implantable medical device for electrically stimulating the heart to beat includes a sense circuit for detecting cardiac electrical activity. The sense circuit includes a band pass filter with an adjustable frequency response. The frequency response can be repeatedly adjusted after implantation of the medical device and preferably is adjusted upon detection of the loss of normal sinus rhythm (NSR) in the heart's atria. The loss of NSR often indicates atrial fibrillation (AF), and the filter's frequency response is adjusted to increase the sensitivity of the sense circuit to the cardiac electrical activity typical during AF. The medical device is calibrated during implantation or at subsequent doctor visits with the aid of a calibration device external to the body. Cardiac electrical activity in the form of an electrogram is transmitted from the medical device to the external calibration device. The transmitted electrogram preferably includes both NSR and AF rhythms.

Control Of Pacing Rate In Dual-Chamber, Rate-Adaptive Pacemakers

US Patent:

56096135, Mar 11, 1997
Filed:

May 3, 1995
Appl. No.:

8/433788
Inventors:

Drury Woodson - Angleton TX
Michael Lee - Angleton TX
Joseph Vandegriff - Angleton TX
Eckhard Alt - Ottobrunn, DE
Lawrence J. Stotts - Angleton TX
Assignee:

Intermedics, Inc. - Angleton TX
International Classification:

A61N 100
US Classification:

607 19
Abstract:

A programmable dual-chamber artificial cardiac pacemaker senses atrial activity and normally tracks the sensed atrial activity in pacing the ventricular activity. An accelerometer located in the case of the pulse generator portion senses physical exercise by a patient when the pacemaker is implanted in the patient, and generates a rate control signal indicative of extent of the sensed physical exercise. The pulse generator is programmed for ventricular pacing rate control in multiple rate zones bounded by rate limits including a ventricular tracking limit (VTL) that varies dynamically with sensed physical exercise and a higher mode switch rate. The ventricular pacing rate tracks the sensed atrial activity on a 1:1 basis for atrial rates below the dynamic VTL (DVTL) during a predetermined interval of time for which the DVTL applies, and tracks the sensed atrial activity in Wenckebach behavior for atrial rates above the DVTL up to the mode switch rate with the ventricular pacing rate limited by the DVTL. The mode switch rate is set to effect a switch from dual-chamber to single-chamber mode when the sensed rate of atrial activity exceeds the mode switch rate for a programmed number of cardiac cycles, in which the ventricular pacing rate is controlled solely by sensed spontaneous ventricular activity without regard to the DVTL or sensed physical exercise. The mode switch rate also effects a reversion to the dual-chamber mode when the sensed rate of atrial activity drops below the mode switch rate for a programmed number of cardiac cycles, in which the ventricular pacing rate is controlled according to the respective one of the multiple rate zones in which the atrial activity rate is present.

Diagnostic Test Protocol In An Implantable Medical Device

US Patent:

58738940, Feb 23, 1999
Filed:

Feb 17, 1998
Appl. No.:

/025123
Inventors:

Joseph W. Vandegriff - Brazoria TX
Bryan J. Thome - Angleton TX
Assignee:

Sulzer Intermedics Inc. - Angleton TX
International Classification:

A61N 1362
US Classification:

607 9
Abstract:

An implantable medical device electrically stimulates the heart to beat and senses electrical activity in the heart. The medical device generally includes a processor, a plurality of electrodes, and a sense amplifier. The medical device is capable of performing a variety of diagnostic tests, such as a sensing test in which a suitable sensitivity setting is computed for the sense amplifier. An external programmer is also provided to initiate the diagnostic tests. The programmer transmits a start signal to the implantable medical device and the medical device's processor initiates the diagnostic test specified by the programmer via the start signal. The implantable device is capable of completing the diagnostic test without further communication from the programmer or may initiate communication with the programmer during a refractory period in which signals from the programmer will not interfere with the diagnostic test. In the latter case, the programmer responds before the refractory period ends.
