Abstract
An introducer needle for accessing a body lumen includes an annular-shaped body having a distal end and a proximal end, a leading edge formed on the distal end, and a slot defined in the leading edge and extending proximally from the distal end. In at least one example, the slot can include a first edge and a second edge, the first edge and the second edge each extending proximally from the leading edge and being separated by a central angle greater than 90 degrees and less than 360 degrees. The first end and the second edge are in continuous communication with the leading edge.

An introducer needle for accessing a body lumen, comprising:
- an annular-shaped body having a distal end and a proximal end;
- an open perimeter leading edge formed on the distal end;
- and
- a slot defined in the leading edge and extending proximally from the leading edge.
An introducer needle configured to cut a flap in a body lumen wall, comprising an annular-shaped body having a distal end and a proximal end, the distal end having of the annular-shaped body having an open perimeter leading edge, a first edge and a second edge, the first edge and the second edge each extending proximally from the leading edge and being separated by a central angle greater than 90 degrees and less than 360 degrees, the first end and the second edge being in continuous communication with the leading edge.
An introducer needle for accessing a body lumen, comprising:
- an annular-shaped body having a distal end and a proximal end, the distal end including opposing edges that are generally parallel to a central axis of the annular-shaped body;
- an open perimeter leading edge formed on the distal end;
- and
- a slot defined in the leading edge and extending proximally from the leading edge, the opposing edges of the distal end defining a portion of the slot extending proximally from the distal end.
