Abstract

Tubular products are provided by applying a first, inner plastic layer onto a core wire and by applying a wire sheathing onto the first plastic layer as a continuous structure thereon. The wire sheathing is then locally removed to provide defined, spaced areas without wire sheathing and intermediate areas including the wire sheathing, and the structure thus provided is covered by applying a second, outer plastic layer thereon, thereby providing a strand structure. As a next step, this strand structure is cut at one limitation of each area without wire sheathing, whereby strand pieces are provided having one end portion which has no wire sheathing therein. The core wire piece left in each strand piece is then removed, thereby providing a tubular product having a body portion including wire sheathing and being completely integral with an end or tip portion without wire sheathing. Due to the complete lack of discontinuity between body portion and tip portion, the tubular products are very suited for use as reliable catheters, and to that end the tip portion can be appropriately formed as needed.
