Embodiment Construction

[0012] As discussed above, embodiments of the present invention relate to a gastrointestinal catheter having feeding and aspiration channels.

[0013] Catheters may be delivered by piercing directly through the abdomen and stomach or bowel wall. Some directly placed catheters can be guided through the normal G-I tunnel to reach more distal duodenal or jejunal feeding and / or aspiration sites.

[0014] Alternatively, the catheter can be introduced indirectly and less traumatically into the body through a proper opening (eg, nasal passage) and then through the proper G-I passage to gastric or intestinal feeding and / or aspiration sites.

[0015] Medical catheters are made of biocompatible elastomers, such as polyurethane. For example, in a single lumen polyurethane catheter, there is a minimum wall thickness that will withstand the expected forces that may cause buckling. Therefore, the walls are relatively thick to prevent buckling. However, it is manufactured as thin as possi...

Abstract

A multi lumen gastrointestinal catheter is disclosed. The multi-lumen gastrointestinal catheter has a flexible partition separating a feeding and an aspiration channel. A third smaller inflation channel is positioned within the outside exterior wall at the site of the flexible partition to avoid kinking at the inflation channel site, without need to re-enforce the weakened wall.

Description

technical field [0001] The invention relates to a multi-lumen catheter. More specifically, the present invention relates to a triple lumen catheter having two relatively large central channels, and a smaller channel in the peripheral wall. Background technique [0002] Physicians use feed-relief catheters (gastrointestinal catheters) for distal feeding and proximal suction. They spaced the feed and suction (pump) sites more than three inches to prevent unnecessary removal of some or all of the feed. The feed-decompression catheter must be capable of long-term retention within the patient's gastrointestinal (G-I) tract. [0003] Some catheters are single lumen catheters, while others are dual lumen devices including feed and suction tubes. Such single and dual lumen catheters are disclosed in the following U.S. Patent Nos. 3,618,613, 4,543,089, 4,642,092, 4,705,511, 4,806,182, 5,334,169, 5,520,662, 5,599,325, 5,676,659 , Nos. 5,807,311, 5,947,940, 6,447,472, 6,508,804, 6,...
