摘要：
A device for cleaning the interior wall of a catheter has a cleaning lumen and a non-inflatable removal element comprising a sliding collar that has a first location as the cleaning lumen advances and a second location as the cleaning lumen retracts within the catheter. A sliding collar has a first position when unconstrained and a second position when within the catheter. The removal element self-positions the device concentrically within the catheter. Suction is desirably applied to the cleaning lumen during use.
