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.
