Abstract
An intravascular blood pump (100) comprises a tip (110), a first region (120) with at least one blood through-opening (121), a flow cannula (130), a second region (140) with at least one blood through-opening (141), a motor-operated pump mechanism (150) and a conducting cable (170). At least in the region of the flow cannula (130), at least one electrical conductor track is realized by a surface coating structure.

- a tip;
- a first region comprising at least one blood through-opening;
- a flow cannula;
- a second region comprising at least one blood through-opening;
- a motor-operated pump device;
- and
- a conducting cable,
- wherein at least one electrical conductor track comprising a surface coating structure in at least a region of the flow cannula;
- and
- wherein the at least one electrical conductor track extends about a spiral structure of the flow cannula.
A method of manufacturing electrical conductor tracks in a region of an intravascular blood pump, the method comprising:
- applying an insulating base layer to a coatable material;
- applying a photoresist material;
- applying a conductor track structure, wherein the conductor track structure is applied by sputtering;
