ABSTRACT:
A pacing catheter having improved torque control properties, including a polymeric tube having an electrically conductive torque member passing through the tube center. The torque member is tapered near the distal end where it is secured to a cup-shaped electrode adapted to fit over the distal end of the polymeric tube. The space between the polymeric tube and the torque member is filled with a polymeric or elastomeric material in fluid form such that a solid, but flexible, polymeric composition is formed which adheres to both the inside of the polymeric tube and the outside of the torque member. The solidified liquid polymeric material allows rotation force applied anywhere along the hollow outer tube to be directly transmitted to the central torque member.
