Abstract

A multi-lumen catheter including a generally cylindrical body enclosing a first and second lumen separated by a generally planar septum. A first and second tip section extend from a distal end of the body. The first and second tip section may each include a generally planar surface. The second tip section may include a first segment extending from the distal end of the body to a transition segment and a second segment extending from the transition segment to a distal end of the second tip section.

Claims (9)

1. A multi-lumen catheter, comprising:

a generally cylindrical body enclosing a first and second lumen separated by a generally planar septum;

a first tip section extending from a distal end of the body including a generally planar surface extending from the septum and an opening in a distal end surface oblique to the planar surface; and

a second tip section including a first segment with a first cross-sectional area extending from the distal end of the body to a transition segment and a second segment with a second cross-sectional area greater than the first cross-sectional area extending from the transition segment to a distal end of the second tip section.

2. The multi-lumen catheter according to claim 1 , wherein the distal end surface of the first tip section includes rounded corners.

3. The multi-lumen catheter according to claim 1 , wherein the distal end of the second tip section includes a beveled surface forming an angle with a longitudinal axis of the second tip section in a range of about 25 degrees and about 75 degrees.

4. The multi-lumen catheter according to claim 1 , wherein the planar surface of the first tip section includes a first planar surface opening adjacent the distal end of the body.

5. The multi-lumen catheter according to claim 4 , wherein the planar surface of the first tip section includes one or more planar surface openings distal to the first planar surface opening.

6. The multi-lumen catheter according to claim 1 , wherein a medial portion of the body is curved.
