In accordance with embodiments of the present invention, a debris removal system is provided for a body-space drainage system having one or more body tubes with a body tube lumen disposed therein. The debris-removal system comprises a cleaning member, a collapsible sheath, and a coupler. The cleaning member is an elongated member wherein the distal end is adapted to enter the body tube lumen at or near the body-tube proximal end and adapted to be advanced distally at least a portion of a length of the body tube lumen. The collapsible sheath is adapted to contain at least a portion of the cleaning member that is not contained within the body tube lumen. The collapsible sheath is flexible so as to allow external digital manipulation of the cleaning member proximal end within of the collapsible sheath, while retaining the sterile environment of the body-space drainage system.
