Abstract: A catheter 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 with an omnidirectional distal end and a concentric needle port. The tip electrode houses a magnetic device and a position sensor in an integrated configuration that facilitates a path in the tip section for extension and retraction of a component, including an injection needle, 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 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.

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.

Abstract: A device and system for automating catheter needle injection has a first actuator that extends a needle past the distal end of the catheter, a second actuator that depresses a plunger to deliver injectate through the needle and an agitator assembly to agitate the injectate before it enters the needle. The device and system may also include a force sensor coupled to the plunger to sense pressure to detect occlusion, and an optical sensor to sense movement of the second actuator.
