Atrial defibrillation system having patient selectable atrial fibrillation detection
First Claim
Patent Images
1. An atrial defibrillation system comprising:
- an implantable atrial defibrillator including an atrial fibrillation detector for detecting atrial fibrillation and a cardioverter for cardioverting the atria of a heart, the implantable atrial defibrillator further including a receiver for receiving commands from an external nonimplanted transmitter; and
a nonimplantable communication device adapted for use by the patient including a transmitter for transmitting a first command to the receiver for activating only the atrial fibrillation detector to cause the atrial fibrillation detector to detect for atrial fibrillation and wherein the cardioverter is not activated in response to the detection of atrial fibrillation unless a further command is transmitted from the nonimplantable communication device to the receiver in the implantable atrial defibrillator.

Abstract
An atrial defibrillation system includes an implantable atrial defibrillator having an atrial defibrillation detector for detecting atrial fibrillation and a cardioverter for cardioverting the atria of a heart. The implantable atrial defibrillator further includes a receiver for receiving commands from an external nonimplanted transmitter. A nonimplantable communication device includes a transmitter for transmitting a command to the receiver. The command causes only the atrial fibrillation detector to be activated resulting only in the detection for atrial fibrillation without committing to atrial fibrillation cardioversion should atrial fibrillation be detected.

5. An atrial defibrillation system comprising:
-
an implantable atrial defibrillator including an atrial fibrillation detector for detecting fibrillation of a patient'"'"'s atria, an atrial cardioverter for applying cardioverting electrical energy to the patient'"'"'s atria, a receiver for receiving operation commands transmitted from an external transmitter, and a mode selecting stage for causing the defibrillator to operate in a first mode of operation wherein only the atrial fibrillation detector is activated to detect for atrial fibrillation and wherein the cardioverter is not activated if atrial fibrillation is detected or in a second mode of operation wherein the atrial fibrillation detector is activated to detect for atrial fibrillation and the cardioverter is automatically activated for applying cardioverting electrical energy to the patient'"'"'s atria if atrial fibrillation is detected; and
a nonimplantable communication device dimensioned to be hand-held and operable by the patient including a transmitter for selectively transmitting a first operation command to cause the mode selector stage to render the implantable atrial defibrillator in the first mode of operation and a second operation command to cause the mode selector stage to render the implantable atrial defibrillator in the second mode of operation. - View Dependent Claims (6)

7. A method of operating an atrial defibrillation system including an implantable atrial defibrillator including an atrial fibrillation detector for detecting atrial fibrillation, a cardioverter for cardioverting the atria of a heart, and a receiver for receiving commands transmitted from an external nonimplanted transmitter in a nonimplantable communication device adapted for use by the patient, comprising the steps of:
-
transmitting a first command from the nonimplantable communication device to the implantable atrial defibrillator; and
activating only the atrial fibrillation detector to detect for atrial fibrillation in response to the first command and not automatically activating the cardioverter if atrial fibrillation is detected. - View Dependent Claims (8, 9)
transmitting a further command from the nonimplantable communication device to the implantable atrial defibrillator; and
activating the atrial fibrillation detector to redetect for atrial fibrillation and automatically activating the cardioverter to cardiovert the atria in response to redetection of atrial fibrillation in response to the further command.

9. The method of claim 7 wherein the nonimplantable communication device includes a receiver for receiving status messages transmitted from a transmitter in the implantable atrial defibrillator and comprising the additional steps of transmitting a status message indicative of detected atrial fibrillation from the implantable atrial defibrillator to the nonimplantable communication device and providing a perceptible indication in response to receipt of the status message by the nonimplantable communication device.
