Abstract: Cleaning devices described herein can provide a hybrid fin and wiper system to facilitate removal of residual solids and liquids from a tubular device (e.g., endoscope), even in a single pass. The cleaning devices described herein can provide pressure equalization and release to effectively clean a blind channel without causing hydraulic compaction of debris. The cleaning devices described herein can provide a connection system that facilitates adjustment and customization based on the needs of a particular application.

Abstract: A pull through having a filament about which, at least in part, there is carried at least one mass to fulfil a cleaning role, wherein said mass defines a sheath at least in part on the filament and at least two radial fins (A) integral with and/or carried by the sheath or extension thereof, and (B) axially spaced with respect to the sheath axis and the filament axis, and wherein said fins are each substantially radially directed with respect to said axes axis yet are of a profile and are formed in a material such that each, without any substantial interference of the other, can assume a configuration for a conduit to be cleaned smaller than that notionally just touchable by the undeformed fins.

Abstract: A pull through such as might be used for an endoscope where a thermaplastics monofilament substantially free of spool or coil memory has molded thereon a desirable thermoplastic mass profile in a material of lower melting point than at least part of the filament, such melting point differential with preferably pre-heating of the filament ensuring an appropriate keying of the profile on the filament.
