1. A medical device for introduction into a human body comprising:
- a generally tubular body;
a plurality of ring-shaped electrodes coupled with the tubular body, wherein the ring-shaped electrodes are arranged in at least two pairs, wherein a spacing separating the electrodes of a pair is less than a spacing separating adjacent pairs; and
at least one printed circuit comprising a plurality of conductive traces in communication with the plurality of ring-shaped electrodes,wherein at least a portion of the at least one printed circuit is internal to the generally tubular body.

Abstract
A catheter or lead having a flexible printed circuit for conveying signals and/or energy. Each trace may be in electrical connection with one or more external electrical contacts. More specifically, each trace is typically electrically connected to a single contact. The traces and contacts may assist in diagnosis and/or detection of bio-electrical signals emitted by organs, and may transmit such signals to a connector or diagnostic device affixed to the catheter. The external electrical contacts may detect bioelectric energy or may deliver electrical or thermal energy to a target site.

24. A flexible printed circuit board adapted for use with a medical device comprising:
-
a flexible substrate defining a first section and a second section, the first section being narrower than the second section; the flexible substrate further defining at least one first conductive trace and at least one second conductive trace, the at least one first conductive trace being arranged generally angularly to the at least one second trace; the at least one first conductive trace is arranged along the first section of the flexible substrate; and the at least one second conductive trace is arranged generally longitudinally along at least a portion of the second section. - View Dependent Claims (25, 26, 27, 28, 29)
