Abstract
The present invention provides conformable intralumen electrodes for use with medical catheters. The electrodes are made of a conductive polymeric material that is introduced into the lumen of a catheter through an opening cut in the peripheral wall in the catheter. A conductive lead threaded through the lumen of the catheter terminates in a distal end at the opening in the catheter and is completely embedded within the polymeric material introduced into the opening, thereby establishing electrical contact between the conductive polymeric electrode and the conductive lead. The conductive polymeric material fills the opening adhering to the walls of the catheter tube, thereby ensuring secure, long lasting attachment.
