Abstract
Abstract An atrial defibrillation system includes an implantable atrial defibrillator including an atrial fibrillation detector and an atrial cardiovertor, and an external communication device dimensioned to be hand-held and including an RF transmitter for transmitting a command signal to the implanted defibrillator. The implantable defibrillator includes a receiver for receiving the command signal, activation means responsive to receipt of the command signal for activating the atrial fibrillation detector and the atrial cardiovertor if the atrial fibrillation detector detects atrial fibrillation, and an RF transmitter for transmitting an acknowledgment signal to the external communication device responsive to the receiver receiving the command signal. The external communication device further includes a receiver for receiving the acknowledgment signal and an indicator for providing a perceptible indication responsive to receipt of the acknowledgment signal.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
An atrial defibrillation system comprising: an implantable atrial defibrillator including at least one lead having electrode means for sensing atrial activity of a heart and applying cardioverting electrical energy to atria of the heart, an atrial fibrillation detector responsive to the sensed atrial activity, and a cardioverter for providing the cardioverting electrical energy; and a portable external communication device dimensioned to be entirely hand-held and including an RF transmitter for transmitting a command signal to cause the implantable defibrillator to initiate the performance of a task, the implantable defibrillator including a receiver for receiving the command signal, means for performing the task responsive to receipt of the command signal, means for generating an acknowledgment signal to acknowledge receipt of the command signal and the initiation of the performance of the task, and an RF transmitter for transmitting the acknowledgment signal to the external communication device, and the external communication device further including a receiver for receiving the acknowledgment signal and an indicator for providing a perceptible indication responsive to receipt of the acknowledgment signal.
Claim 2
Dependent Claim
