Abstract
A co-axial catheter assembly (100) including a first lumen (110) having a first distal end (114) and a first proximal end (112), and a second lumen (120) having a second distal end (124) and a second proximal end (122). The second lumen (120) extends co-axially with the first lumen (110), wherein the second lumen is at least partially disposed within the first lumen and the second distal end extends distally of the first distal end. The second distal end (124) includes a distal tip (130) and a bulbous projection (240) disposed between the distal tip and the first distal end. A method of inserting the catheter is also disclosed.

1-10. (canceled)
A co-axial catheter comprising:
- a first lumen having a first distal end, a first proximal end, and a longitudinal axis extending therethrough;
- and
- a second lumen having a second distal end, a second proximal end, and extending co-axially with the first lumen, wherein the second lumen is at least partially disposed within the first lumen;
- wherein the second distal end extends distally of the first distal end, wherein the second distal end includes a distal tip and a bulbous projection disposed between the distal tip and the first distal end.
(canceled)
A method of inserting a catheter comprising:
- providing a catheter having:
- a first lumen having a first distal end, a first proximal end, and a longitudinal axis extending therethrough;
- and
- a second lumen having a second distal end, a second proximal end, and extending co-axially with the first lumen, wherein the second lumen is at least partially disposed within the first lumen;
- wherein the second distal end extends distally of the first distal end, wherein the second distal end includes a distal tip and a bulbous projection disposed between the distal tip and the first distal end;
- inserting the distal tip into a blood vessel;
- and
- oscillating the distal tip in a generally circular motion while advancing the distal tip into the vessel.
