Irrigation catheter, single-lumen

A single-lumen irrigation catheter is a flexible tube designed to deliver non‑medicinal fluids such as saline into body cavities that are not part of the circulatory system, including the ear, wound sites, urinary tract, stomach, colon, or uterus. The catheter features a distal end with one or more holes to allow fluid flow and a proximal end that typically attaches to a syringe or pump via a Luer‑lock connection.

These catheters are supplied as sterile, single‑use devices and are regulated as medical devices under the applicable jurisdiction’s device legislation. They are classified according to their intended use and risk profile, and manufacturers must ensure compliance with labeling, sterility, and performance requirements before they can be marketed.
