1. An apparatus for implantation in a selected lumen of vasculature, comprising:
- a first cell that is prismatic and that includes a first plurality of substantially planar battery electrodes that are arranged in layers;
a second cell including a second plurality of substantially planar battery electrodes that are arranged in layers;
a flexible substrate electrically connecting the first cell and the second cell;
a transducer electrically connected to the first cell via the flexible substrate, the transducer to record medical-related data;
a wireless transmitter electrically connected to the first cell and to the transducer via the flexible substrate, the wireless transmitter to transmit the medical-related data; and
a biocompatible flexible housing enclosing the first cell, the second cell, the transducer, the wireless transmitter and the flexible substrate, the biocompatible flexible housing adapted to allow the first cell, the second cell and the transducer to move with respect to one another, the biocompatible flexible housing defining a housing exterior including a form factor shaped as a function of flow stagnation in the selected lumen, the form factor shaped to allow flow in the selected lumen.

Abstract
One embodiment of the present subject matter includes an apparatus for storing energy, the apparatus having a first portion comprising a flexible substrate containing a polymer electrolyte and a second portion adapted to provide a conformable housing surrounding the first portion; wherein the apparatus is adapted to provide a source of energy to an implantable device. The apparatus defines a flexible implantable device capable of traversing the circulatory system of a body with minimal obstruction of flow within the circulatory system. Further provided is a method of implanting an power source within the circulatory system of a subject'"'"'s body.
