Leadless Implantable Cardioverter Defibrillator
First Claim
1. A leadless implantable defibrillator comprising a controller having a controller sensor for sensing patient conditions, a controller electrode for imparting a stimulation to the patient, and a controller wireless communicator, and further comprising at least one remote module having a remote sensor, a remote electrode, and a remote wireless communicator for wirelessly communicating with the controller wireless communicator.

Abstract
A leadless implantable cardioverter defibrillator (5) for treatment of sudden cardiac death includes a controller and at least one remote module. The defibrillator does not require transvenous/vascular access for intracardiac lead placement. The controller is leadless and uses subcutaneous tissue in proximity of the chest and abdomen for both sensing and defibrillation. The controller and one or more remote sensors sense a need for defibrillation and wireless communicate with the controller. The controller and one of the sensors discharge a synchronized defibrillation pulse to the surrounding subcutaneous tissue in proximity to the heart.

15. A method for defibrillating the heart of a patient, the method comprising:
-
implanting a controller in the subcutaneous tissue in proximity to the chest and abdomen; implanting a remote module subcutaneously in a posteriolateral location in the left chest area of the patient; sensing a patient condition at the remote module and at the controller; wirelessly transmitting the patient condition from the remote module to the controller; determining at the controller when defibrillation of the heart is required based on the sensed patient conditions; wirelessly transmitting a defibrillation signal from the controller to the remote module in response to determining when defibrillation of the heart is required; and applying a defibrillation pulse by the controller and the remote module in response to receiving the defibrillation signal.

16. A leadless implantable apparatus for the treatment of sudden cardiac death of a subject wherein the subcutaneous tissue in proximity to the chest and abdomen is used for both sensing and defibrillation, comprising:
-
a controller located in the subcutaneous tissue; a remote module located subcutaneously in the upper right quadrant of the subject'"'"'s chest and in radio frequency communication with the controller; and a microthin patch located in a posteriolateral position in the upper left quadrant of the chest with an electrical wire connected to the controller. - View Dependent Claims (17)
