Abstract
The instant invention is directed toward transseptal puncture needles and transseptal puncture needle assemblies. More specifically, it relates to curved transseptal puncture needles and needle assemblies that facilitate insertion through curved transseptal introducers. Each curved transseptal puncture needle includes a needle tip with a tangential back bevel configuration, a reverse tangential back bevel configuration, or a conical reverse bevel configuration. The axial orientation of the needle tip relative to the needle curvature, whether on the concave side or convex side of the curved transseptal puncture needle, provides additional benefits. The leading edge of the needle tip is located at a distal end of an inner needle tube, and the leading edge of the needle tip may be positioned away from an outer surface of the inner needle tube and adjacent to an inner surface of the inner needle tube.
