Abstract
A biopsy channel for use in an endoscope having a tubular substrate formed of a lubricious material that is wound with a high strength wire filament helically wound thereabout to provide spaces between the windings and a relatively softer elastomeric material blanketing the windings. A top coating also containing a lubricious material is placed over the filler material to provide a tubular structure that can be bent into a tight radius without collapsing.
