Abstract
Tubing for use in gastrointestinal applications includes a hollow tube and a spring positioned inside the tube. The spring is corrosion resistant and helps to prevent kinking of the tubing when the tubing is bent. An encapsulant may be positioned over the spring. The spring may be co-extruded with the tubing.
Claims11
A multi-lumen feeding tube device comprising:
- a multi-lumen tube having at least two lumens at a proximal end thereof and at least one lumen at a distal end thereof, with the at least two lumens comprising at least a gastric lumen and a jejunal lumen;
- a G-J button;
- a jejunal tube inserted into the jejunal lumen, wherein the jejunal tube comprises a cone-shaped portion at a proximal-most end of the jejunal tube that expands radially from the jejunal tube, and the jejunal tube is inserted into an opening in the G-J button into the jejunal lumen such that the cone-shaped portion mates with an interior surface of the G-J button to couple the jejunal tube to the jejunal lumen and the G-J button;
- and
- a spring positioned continuously along a length of the jejunal tube from just below the cone-shaped portion at the proximal-most end in order to provide a kink-resistant feature to the multi-lumen feeding tube device.
