Abstract
A method for producing a medical device comprising the steps of: providing a tubular substrate, said tubular substrate enclosing an internal lumen and being provided with at least one recess in the outer surface, wherein said recess does not form a through going hole into the internal lumen; treating the outer surface of said tubular substrate, preferably by means of surface modification and/or by coating; and forming, after said treating of the outer surface, an opening within said at least one recess to form an access opening to said internal lumen.

A method for producing a medical device, comprising the steps of:
- providing a tubular substrate, said tubular substrate enclosing an internal lumen and being provided with at least one recess in the outer surface, wherein said recess does not form a through going hole into the internal lumen;
- treating the outer surface of said tubular substrate, preferably by means of surface modification and/or by coating;
- and
- forming, after said treating of the outer surface, an opening within said at least one recess to form an access opening to said internal lumen.
A medical device comprising a tubular substrate, said tubular substrate enclosing an internal lumen, and being provided with at least one opening providing access to said internal lumen, wherein at least a part of an outer surface of said tubular substrate is provided with a surface treatment, and preferably a surface modification and/or a coating, wherein the internal lumen is free of said surface treatment, and wherein a wall of said at least one opening is at least partly provided with said surface treatment.
