Method for producing a medical device
First Claim
1. A method for producing a medical device with a lattice structure which is connected at least in some areas to a cover, in which method comprisingthe lattice structure is arranged on a substrate via the side that is to be connected to the cover;
- the lattice structure has the side arranged on the substrate pressed at least partially into the substrate;
the lattice structure is coated with a first layer of a sacrificial material, such that at least some of the interstices of the lattice structure are covered by the first layer, and the first layer, together with the lattice structure, forms a substantially closed surface on the side to be connected to the cover;
the substrate is removed, such that the side of the lattice structure is accessible that is to be connected to the cover;
a second layer for forming the cover is applied to the side of the lattice structure previously pressed into the substrate; and
the sacrificial material is removed.

Abstract
A method for producing a medical device with a lattice structure, connected at least in some areas to a cover. The lattice structure is arranged on a substrate via the side to be connected to the cover, the lattice structure has the side arranged on the substrate pressed at least partially into the substrate, the lattice structure is coated with a first layer of a sacrificial material. At least some of the interstices of the lattice structure are covered by the first layer, and the first layer with the lattice structure on the side to be connected to the cover forms a substantially closed surface, the substrate is removed, making the side of the lattice structure accessible for connection to the cover. A second layer for forming the cover is applied to the side of the lattice structure previously pressed into the substrate, and the sacrificial material is removed.

6. The method as claimed in claim l, wherein the lattice structure, before being coated with the first layer of a sacrificial material, is coated with a start layer.
-
7. The method as claimed in claim l, wherein the sacrificial material of the first layer and/or the start layer are formed from a metallic material, in particular from the same metallic material or from different metallic materials.
-
8. The method as claimed in claim l, wherein the coating of the lattice structure with the start layer is carried out by a gas phase deposition method, in particular a PVD method, in particular by sputtering, and/or the coating of the lattice structure with the first layer of a sacrificial material is carried out by a galvanic method.
-
9. The method as claimed in claim l, wherein, during the coating of the lattice structure with the first layer of a sacrificial material, the lattice structure is partially or completely embedded in the sacrificial material.
