A lumen extension member is provided for a catheter having a catheter body and an elongate electrode coupled to the catheter body. The elongate electrode defines an electrode lumen extending therethrough. The lumen extension member is positioned within the electrode lumen and is coupled to the catheter body. The lumen extension member includes a tubular member including a sidewall and at least one opening that extends through the sidewall.

Flexible tip catheter with extended fluid lumen

An electrophysiology catheter for use with a steerable introducer sheath includes a flexible catheter body having a proximal end and a distal end and at least one hollow elongate tip electrode disposed at the distal end of the catheter body. The hollow elongate tip electrode includes a sidewall having at least one elongate gap that provides flexibility allowing the tip electrode to bend relative to a longitudinal axis of the catheter body. The catheter body is an independent, non-steerable structure, and can be moved via movement of the steerable introducer through which it is introduced into a patient.

Kit for non-invasive electrophysiology procedures and method of its use

An apparatus for dispensing material during a dental or endodontic procedure includes a housing having a motor with an output. A needle heating member including a chamber may receive a prefilled needle of dispensing material. A heater at least substantially surrounds the chamber for heating the material in the needle. A plunger is used to expel the material from the needle during activation of the motor. A reusable protective sheath is provided for disposition on the outside of the housing. A method of manufacturing a needle for use and dispensing a material during a dental or endodontic procedure includes drawing a blank of metal having a closed distal end, bending the blank at a desired angle, and removing a portion of the drawn metal from the distal end to open the distal end thereby forming the dispensing needle.
