Gastrointestinal catheters are indispensable tools in interventional therapy, widely used in the treatment of gastrointestinal strictures and bleeding. With technological advancements, catheter design and materials are constantly being innovated, providing patients with more efficient and safer treatment options.

Bile Duct Catheters

Primarily used for the treatment of bile duct strictures or obstructions, such as bile duct cancer or gallstones. Newer bile duct catheters use nickel-titanium alloy materials, possessing good elasticity and strength, enabling smooth passage through areas of biliary stricture.

**Esophageal Stent Catheter** Esophageal stent catheters are used for dilation therapy in cases of esophageal cancer or postoperative stricture. New catheter designs have improved the stent deployment mechanism, ensuring stable deployment in the correct position and reducing the risk of displacement and complications. **Gastric and Intestinal Tubes** Gastric and intestinal tubes are used for drainage and nutritional support, particularly suitable for patients after gastrointestinal surgery. Modern catheters use soft, transparent materials, increasing comfort and ease of use.

Advances in catheter materials

Nickel-titanium alloys possess superelasticity and shape memory alloy properties, enabling them to adapt to complex digestive tract anatomy and return to their original shape after release.

Medical-grade polymers: Improvements to this material enhance the biocompatibility and anti-infection capabilities of catheters, reducing the risk of postoperative infection.

The continuous advancement of gastrointestinal catheter technology has made interventional gastrointestinal therapies safer and more efficient. By understanding the design features and application scenarios of various catheters, medical teams can better develop treatment plans and improve patient outcomes.
