    Abstract: A transseptal needle includes an elongate needle body having a distal end and a proximal end and a cannular needle tip located proximate the distal end of the needle body. The needle tip has a distal segment, a proximal segment, and a longitudinal axis. An inner surface of the needle tip defines a passageway spanning at least a portion of the needle tip, and an outer surface of the needle tip defines a wall with the inner surface. The distal segment of the needle tip also includes a wedge surface and a dome-shaped region. The wedge surface forms a wedge angle of other than 90 degrees relative to the longitudinal axis. The dome-shaped region, which intersects the wedge surface, includes at least two bevels that intersect the wedge surface and that intersect each other at one or more points on the needle tip.

    Abstract: An ablation catheter is disclosed having proximal and distal ends and an external surface, a lumen contained within the catheter body, a plurality of openings in the surface of the catheter, wherein the openings are in communication with the lumen, one or more electrodes secured within the catheter within the lumen and a source for conductive media to be introduced into the lumen to contact the electrode. The ablation catheter also may contain a conductive media flow control system which controls the flow of the conductive media through the openings in the surface of the catheter. Also disclosed is a process for ablation of human tissue including introducing an ablation catheter into the human body to a location to be ablated, passing a conductive media through a lumen of the catheter to contact one or more electrodes, passing the conductive media through the openings in the catheter body to contact the tissue to be ablated, and conducting energy from the electrode through the conductive media to the tissue for a sufficient period of time to ablate the tissue.
