Tunneled catheter

A tunneled catheter is a specialized medical tube inserted under the skin into a large blood vessel, typically in the chest or neck. It’s designed to provide long-term access for treatments like medication, fluids, or dialysis. The catheter has a longer pathway under the skin, which helps reduce infection risk and keeps the entry site stable. Because it stays in place for weeks or months, it’s commonly used for patients requiring ongoing treatment, offering a reliable alternative to repeated needle sticks. Healthcare professionals carefully place and maintain these catheters to ensure safety and proper function.
