摘要：
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.
