Abstract:
1. A flexible implantable cardiac device configured for placement within a pericardial space, adjacent an epicardial surface having a contour, said device comprising: a capacitor; a battery separate from the capacitor; an electronic component separate from both the capacitor and the battery and adapted to sense cardiac signals and to generate cardiac stimulation signals; a plurality of flexible interconnections adapted to couple the electronic component to the capacitor and the battery; a flexible housing having a longitudinal axis and containing the electronic component, the capacitor, the battery and the interconnections, wherein the electronic component, the capacitor and the battery are spaced apart in a linear arrangement along the longitudinal axis of the housing such that the only physical connection between the electronic component, the capacitor and the battery is provided by the interconnections, and the spacing of the electronic component, the capacitor and the battery in combination with the flexibility of the housing and the flexibility of the interconnections provides a device configured to conform to the contour of the epicardial surface; and four electrodes carried by the flexible housing and coupled to the electronic component, wherein the spacing of the four electrodes and the flexibility of the housing are such that the device is adaptable to form an arcuate shape whereby the four electrodes form a first pair and a second pair of substantially diametrically opposite electrodes.
