Abstract
A cleaning tube may have an expansion portion that includes two or more slits. The cleaning tube may be deployed by linearly compressing the expansion portion, thus causing the tube to bulge into a disc through expansion of the slits. A sheath may cover the expansion portion to seal the slits. So deployed, the cleaning tube may be translated in a contaminated tube to remove contamination.
