US Patent:

6731983, May 4, 2004
Filed:

Feb 25, 2002
Appl. No.:

10/082981
Inventors:

James H. Ericksen - North Oaks MN
Robert A. Betzold - Fridley MN
Catherine R. Condie - Shoreview MN
Jeffrey M. Gillberg - Coon Rapids MN
Robert W. Stadler - Shoreview MN
John C. Stroebel - Blaine MN
Troy E. Jackson - New Brighton MN
Assignee:

Medtronic, Inc. - Minneapolis MN
International Classification:

A61N 136
US Classification:

607 14
Abstract:

A device-implemented software system operates a detection window and adjusts PAV as needed after confirming the presence or detection of evidence of an arrhythmia. The detection window is monitored based on a preferred length. If the detection window is shorter than required, intervals are adjusted for a specific pacing rate. Further, the software system provides means for selecting detection over pacing based on an analysis of a preferred length in the presence of evidence of an arrhythmia.

US Patent:

6752765, Jun 22, 2004
Filed:

Nov 17, 2000
Appl. No.:

09/715637
Inventors:

Donald N. Jensen - Roseville MN
Linda L. Ruetz - New Brighton MN
Catherine R. Condie - Shoreview MN
Yong Kyun Cho - Maple Grove MN
Ulla Strobel - Zurich, CH
Scott Davie - St. Paul MN
Assignee:

Medtronic, Inc. - Minneapolis MN
International Classification:

A61N 1365
US Classification:

600536, 600547, 607 18
Abstract:

An implantable device having enhanced capabilities for monitoring a patients heart rate and respiration trends over extended periods of time is disclosed. The information collected by the implantable device may be stored and telemetered to an associated external device such as a device programmer for display and analysis. Heart rates are measured by measuring the time intervals between sensed depolarizations of a chamber of the patients heart and preceding sensed depolarizations or delivered pacing pulses. Intervals may be measured in the ventricle and/or atrium of the patients heart. According to another aspect of the invention, an implanted impedance sensor is employed to monitor minute ventilation. The heart rate and minute ventilation data is used to develop long-term trend data used for diagnostic purposes. In one embodiment of the invention, heart interval and minute ventilation measurements are taken only during defined time periods of the night and/or day when the patient is at rest.

Implantable Medical Device (Imd) System Configurable To Subject A Patient To A Stress Test And To Detect Myocardial Ischemia Within The Patient

US Patent:

6882883, Apr 19, 2005
Filed:

Aug 31, 2001
Appl. No.:

09/945195
Inventors:

Catherine R. Condie - Shoreview MN, US
Robert W. Stadler - Shoreview MN, US
Lee Stylos - Stillwater MN, US
Assignee:

Medtronic, Inc. - Minneapolis MN
International Classification:

A61N001/362
US Classification:

607 11
Abstract:

Various implantable medical devices (IMDs) are disclosed for implantation in a patient. The IMD includes pacing circuitry configured to selectively produce pacing pulses at a programmable pacing rate. In one embodiment, the IMD is configurable to subject a patient to a stress test. The IMD may be configurable to subject the patient to the stress test at the time specified by stored timing information, or in response to a signal (e. g. , from a patient activator). Another embodiment of the implantable medical device (IMD) includes sensor circuitry, a memory for storing data, and a control unit. The sensor circuitry produces sensor data relating to cardiac condition. The control unit is configurable to store the sensor data in the memory until a trigger signal is received. Methods are described for performing a stress test in a patient with an IMD, and for subsequently reproducing cardiac operational states.

Automatic Rate Response Sensor Mode Switch

US Patent:

6885891, Apr 26, 2005
Filed:

Dec 31, 2001
Appl. No.:

10/040120
Inventors:

Yong Kyun Cho - Maple Grove MN, US
Catherine R. Condie - Shoreview MN, US
Assignee:

Medtronic, Inc. - Minneapolis MN
International Classification:

A61N001/365
US Classification:

607 18, 607 27
Abstract:

An automatic rate response sensor mode switch is implemented in an implantable medical device to monitor and isolate any sensor in an integrated sensor scheme. The isolated sensor is based on identification of problems associated with the sensor. The implantable medical device will switch to operate with the remainder sensor(s). Specifically, an algorithm tests and determines sensor status to initiate and operate the sensor mode switch. The software continuously monitors, isolates or qualifies a sensor to come back on-line automatically.

US Patent:

7031772, Apr 18, 2006
Filed:

Apr 29, 2002
Appl. No.:

10/134560
Inventors:

Catherine R. Condie - Shoreview MN, US
John D. Wahlstrand - Shoreview MN, US
Gerald A. Portzline - Fridley MN, US
Yong Kyun Cho - Maple Grove MN, US
John S. Brandstetter - Coon Rapids MN, US
Luc R. Mongeon - Minneapolis MN, US
Assignee:

Medtronic, Inc. - Minneapolis MN
International Classification:

A61N 1/365
US Classification:

607 20, 607 18
Abstract:

A method and an apparatus for performing rate responsive control in an implantable medical device using a scaling factor. Sensor data is acquired using a sensor operatively coupled with the implantable medical device. At least one setpoint for controlling a rate of therapy is generated, the setpoint being based upon the sensor data. A scaling factor adjustment process is performed for scaling the internal sensor data to correlate the sensor data to the setpoint. The rate of therapy is adjusted based upon the scaling factor adjustment.

The external data injection process includes providing the external data to the implantable medical device. A second stress test is performed, the second stress test being substantially similar to the first stress test. Internal data resulting from the second stress test is acquired. Internal data resulting from the second stress test along with the external data resulting from the first stress test, are processed.
