Abstract
A catheter adapted for ablation, mapping, injection, and directional control by an external magnetic system has a catheter body, an intermediate section, and a tip section having a tip electrode configured with an omnidirectional distal end and a concentric needle port. The tip electrode houses a magnetic device and a position sensor arranged in an integrated configuration, wherein the configuration facilitates a path in the tip section for a component, including an injection needle, to extend through the tip section for extension and retraction with reduced stress and friction. The integrated configuration is an efficient use of space in the tip electrode that allows the tip section to carry both the position sensor for determining location and orientation of the tip section and the necessary volume of magnetic or magnetizable material to accomplish magnetic navigation. The catheter also includes a very soft and flexible intermediate section and an even softer and more flexible distal transitional section carrying additional magnetic members to facilitate remote magnetic navigation.
