Triple lumen catheter with occlusion resistant tip
First Claim
1. A catheter comprising:
- an elongated tubular body defining a longitudinal axis and extending to a distal end thereof, the tubular body having a first lumen and a second lumen with a septum disposed therebetween, the tubular body including a first wall that defines the first lumen and a second wall that defines the second lumen, a portion of the septum extending distally beyond the first lumen and the second lumen;
wherein the first wall includes a first wall extension that extends in a spiral configuration from the first lumen about the longitudinal axis and is spaced apart from the portion of the septum; and
the tubular body having a third lumen.

Abstract
A catheter is provided that includes an elongated tubular body extending to a distal end. The tubular body has a first and a second lumen with a septum disposed therebetween. The tubular body includes a first wall that defines the first lumen and a second wall that defines the second lumen. A portion of the septum extends distally beyond the first lumen and the second lumen. The first wall includes a first wall extension that extends distally beyond the first lumen and is spaced apart from the portion of the septum. The first wall extension defines a concave surface facing the portion of the septum. In an alternate embodiment, the catheter includes a tip with spiraled configuration. The catheter may include a third lumen.

21. A catheter comprising:
-
an elongated tubular body defining a longitudinal axis and extending to a distal end thereof, the tubular body having a first lumen and a second lumen with a septum disposed therebetween, the tubular body including a first wall that defines the first lumen and a second wall that defines the second lumen, a portion of the septum extending distally beyond the first lumen and the second lumen; wherein the first wall includes a first wall extension that extends in a spiral configuration from the first lumen about the longitudinal axis and is spaced apart from the portion of the septum; and the tubular body having a third lumen of substantially circular cross section and extending distally beyond the first and second lumens, said third lumen located coaxially along a center longitudinal axis of said tubular body so to bisect said septum, an exterior of the third lumen is defined by a first arcuate wall and a second arcuate wall, the third lumen is separated from the first lumen by said first arcuate wall, and the third lumen is separated from the second lumen by said second arcuate wall.
