Filed:

Feb 25, 2000

Appl. No.:

09/513886

Inventors:

Jeffery D. Snell - Oak Park CA

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 137

US Classification:

607 27, 607 28

Abstract:

An implantable cardiac stimulation system and method wherein the implanting physician may store, in the system, parameters which define the expected performance of the device in conjunction with the programming of the device to address the needs of the patient. The person performing follow-up testing of the device and its interaction with the patient may, with an external programmer, be advised of the expected performance of the device at follow-up. The implanted device generates performance data indicative of the interaction between the device and the patients heart. Limits, defining the expected interaction of the device and the patients heart associated with the generated data are established and stored, either in the implantable device or in the external programmer. After implant, the generated data is evaluated to determine if the generated data satisfies the established limits. The evaluation results are then reported.

Appl. No.:

09/410517

Inventors:

Jeffery D. Snell - Oak Park CA
Laurence S. Sloman - West Hollywood CA

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 137

US Classification:

607 31, 607 32, 607 60

Abstract:

An implantable cardiac stimulation device establishes communication with at least first and second external devices which communicate using first and second communication protocols, respectively, and wherein the first and second protocols are different. The implantable device includes a pulse generator configured to generate stimulation pulses and a telemetry circuit arranged to establish communication with the first and second external devices according to the first and second communication protocols, respectively. A control circuit coupled to the telemetry circuit and the pulse generator detects the first and second external devices based upon the protocol used in establishing communication to provide a first response when the first external device is detected and a second response when the second external device is detected.

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 108

US Classification:

607 30, 607 32, 607 59, 607 60

Abstract:

To permit remote programming of implantable cardiac stimulation devices such as pacemakers, a central device programmer is provided in conjunction with a network of remote telemetry units for use in patient homes or in remote clinics. To reprogram a device implanted within a patient, a physician enters programming commands within the central programmer which relays the programming commands to a remote telemetry unit in proximity to the patient. The remote telemetry unit, in turn, forwards the programming commands to the implanted device. In this manner, the patient need not return to the physician for reprogramming of the device. Remote telemetry units may be provided within patient homes, clinics, hospital emergency rooms, hospital patient rooms, and the like. Depending upon the implementation, different levels of programmability may be permitted depending upon the degree of supervision of the patient. For an unsupervised patient, limited programmability is permitted.

Appl. No.:

Inventors:

Jeffery D. Snell - Chatsworth CA

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 108

US Classification:

607 59

Abstract:

Upon interrogating a pacemaker, implantable cardioverter defibrillator or other implantable cardiac stimulation device, an external programmer accesses previously-stored physician comments maintained within the implanted device. The programmer disables any reprogramming of the implanted device until the physician comments have been displayed via the programmer for review by the physician or other medical professional seeking to reprogram the implanted device. In this manner, critical information pertaining to a previous programming session is presented to the physician before any additional reprogramming is permitted so as to ensure that the critical information is reviewed. In one example described herein, physician comments are designated as being either general or parameter-specific. General comments are displayed for review before any reprogramming is permitted. Parameter-specific comments are displayed for review only if the physician seeks to reprogram particular parameters associated therewith.

Inventors:

Jeffery D. Snell - Chatsworth CA, US

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61B005/04

US Classification:

600519, 607509

Abstract:

Methods and systems for monitoring heart rate recovery are described. In one embodiment, an implantable monitoring device monitors a patient's heart activity. The monitor looks for periods of increased activity, such as those that are experienced during some level of exercise, and periods of lesser activity (such as rest) directly following. The patient's heart rate recovery is monitored as the heart recovers from the active period to the rest period. Data associated with the patient's heart rate recovery can then be diagnostically used to ascertain certain conditions associated with the patient.
