Abstract
A method is provided for applying a cover layer (9) to a net structure (4) to be used for medical purposes, in particular a thrombosis filter. The net structure (4) is applied to a planar substrate (1) that covers openings (5) of the net structure on one side, wherein the openings (5) across the uncovered side are filled with a sacrificial material (7), in particular copper. The net structure (4) is lifted from the substrate (1). A cover layer (9) is deposited on the surface previously covered by the substrate, and the sacrificial material (7) is removed.

A method for applying a cover layer to a net structure to be used for medical purposes, the method comprising the steps of:
- applying the net structure to a planar substrate covering openings of the net structure on one side,
- filling the openings across an uncovered side of the net structure with a sacrificial material,
- lifting the net structure from the substrate,
- depositing a cover layer on a surface previously covered by the substrate, and removing the sacrificial material.
A thrombosis filter having a net structure formed from wire for placing in a blood vessel lumen, wherein a planar cover layer is applied by a deposition method on one side of the net structure, and wherein the cover layer at least partially covers openings of the net structure.
A method for applying a cover layer to a net structure to be used for medical purposes, in particular a thrombosis filter, comprising the steps of
- at least partially filling openings of the net structure with a sacrificial material in such a way that a continuous surface is formed,
- depositing the cover layer on the continuous surface, and
- subsequently removing the sacrificial material.
