What is a “lumen”?
In simple terms, a lumen is the inside space of a tubular structure. In tubing, lumens are often used for air or fluid evacuation or delivery, or to provide separate access ports for other devices like surgical scissors, stents, or cameras.
New England Tubing Technologies manufactures both single and multi-lumen tubing in both reinforced and unreinforced configurations with a variety of custom lumen geometry options. Common requests are for concentric circular lumens, smaller satellite lumens around a larger lumen, the classic double D, oval lumen, “smiley face” lumen, and other shaped lumens.
