First Claim
Patent Images
1. A flexible lead for implantation within a human body, comprising:
- a lead length, wherein said lead length extends from a first end to a second end, wherein said first end is coupled to a proximal housing implanted at a first location within a human body, and said second end is coupled to a distal module implanted at a second location within a human body; and
at least two conductors, wherein said at least two conductors extend from the first end to the second end, and wherein said at least two conductors are in electrical communication with at least three electrodes, and wherein said at least three electrodes are greater in quantity than said at least two conductors.

Abstract
A cardiac rhythm management apparatus includes a proximal housing, a distal housing and a lead. The proximal housing includes a first energy storage device. The distal module is implantable within a patient'"'"'s heart, and includes a second energy storage device, at least one electrode, and a control module. The control module controls the delivery of at least one electrical stimulus from the second energy storage device to a location in communication with the patient'"'"'s heart. The lead connects the proximal housing to the distal module and is configured to communicate one or more digital signals between the proximal housing and the distal module.
