Abstract
A tubular conduit is disclosed. The tubular conduit comprises a tubular portion made from a flexible material and an axially extending external helical formation located around the outside of the tubular portion. The external helical formation is for supporting the tubular portion. Optionally the tubular portion also comprises an axially extending internal helical protrusion, which imparts a helical flow to a fluid passing through the tubular portion. It is preferred that the tubular conduit is a vascular graft.
