摘要

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.
