Pull throughs for endoscopes

摘要

A pull through having a filament about which, at least in part, there is carried at least one mass to fulfil a cleaning role. The mass defines a sheath at least in part on the filament and at least two circular fins integral with and/or carried by the sheath radially and axially spaced with respect to the sheath axis and the filament axis. The fins are each substantially radially directed with respect to the sheath axis and the filament axis yet are of a profile and are formed in a material whereby each fin without any substantial interference of the other can clean a conduit of about the fin diameter and/or a conduit greater than 1mm diameter smaller. Each fin provides for 360 cleaning of the conduit. Each fin is of the same of substantially the same diameter as each other fin.
