Abstract
A seed assembly for delivery to an interior of a heart includes an electrical stimulation circuit for delivering an electrical stimulus to cardiac tissue. A first electrode assembly is mechanically and electrically coupled to the seed assembly via a micro lead the first electrode assembly configured to deliver the electrical stimulus generated by the electrical stimulation circuit to the cardiac tissue. The seed assembly and the first electrode assembly are sized and shaped to fit entirely within the heart.
