Abstract
The invention discloses a subcutaneous electrode array or SEA for use in medical devices. The arrangement provides an enhanced capability for detecting and gathering electrical cardiac signals via the array of relatively closely spaced subcutaneous electrodes. Further, switching circuits, signal processors and memory to process electric cardiac signals are implemented to enable a leadless orientation-insensitive SEA scheme for receiving the electrical signal from the heart. The SEA is distributed over the perimeter of the implanted medical device and includes a non-conductive surround shroud of biocompatible material. The surround shroud is placed around the periphery of the case of the implanted medical device. Various configurations of recesses, each of which contain individual electrodes, are implemented to provide an enhanced signal to noise ratio for improved signal quality.
