Marker, useful for magnetic resonance tomography-visualization of medical devices e.g. catheters, needles, endoscopes or papillotomes insertable or implantable into body, comprises magnetic resonance tomography-contrast enhanced marking

摘要

The marker (2, 3, 4) comprises magnetic resonance tomography (MRT)-contrast enhanced marking The marking is formed as a thin film made of coating carrier. The thin film comprises or consists of a nanoscale MRT-contrast coating made of a magnetic material. The MRT-contrast coating is available by physical or chemical vapor deposition. Total thickness of the MRT-contrast coating perpendicular to a layer plane is 400 nm. The thin film is a multilayer and comprises a marker-protective coating applied to the MRT-contrast coating, where the marker-protective coating is glassy or carbonaceous.

The thin film is multilayer, and comprises a marker-protective coating applied to the MRT-contrast coating, where the marker-protective coating is glassy or carbonaceous. The thin layer is obtainable by masking a coating carrier during the coating. An independent claim is included for a method of generating a marker.
