US Patent 7899537 Pericardial cardioverter defibrillator

An implantable pericardial device provides therapy to a heart of a patient. In one embodiment electronics, electrodes and other components are provided in a unitary assembly. These components may be implemented such that the unitary assembly has a sufficient degree of flexibility. The implantable pericardial device may be implanted into the pericardial space using a relatively low-invasive technique such as a sub-xiphoid approach.
