Active can with dedicated defibrillation and sensing electrodes

摘要

Cardiac devices employing an active can and/or electrode assembly with dedicated defibrillation and sensing electrodes. A housing is configured for subcutaneous non-intrathoracic placement in a patient, the housing having a first face and a second face. One of the first and second face is directed away from the patient's heart, and the other of the first and second face is directed towards the patient's heart. A cardiac arrhythmia may be sensed using an electrode assembly positioned in or on the first face of the housing. A cardiac defibrillation therapy may be delivered to the patient's heart using an electrode assembly positioned in or on the second face of the housing in response to the detected arrhythmia.
