Abstract
A lead assembly having a ring electrode is adapted for implant and for connection to a system for monitoring or stimulating cardiac activity. The lead assembly includes a first porous member disposed around the ring electrode at the distal end of the lead assembly, which can be used as a sensing or pacing interface with the cardiac tissue. In addition, a second porous member is disposed over the first porous member and is electrically coupled with the ring electrode.
