An implantable medical device comprising a structural element, the structural element comprising:
- a core layer or region of radiolucent material;
- a layer of radiopaque material overlaying the core layer or region of radiolucent material;
- and
- an outer layer of radiolucent material overlaying the layer of radiopaque material, the outer layer of radiolucent material having a same or greater hardness as the layer of radiopaque material.
An implantable medical device comprising structural element, the structural element comprising:
- a core layer or region of radiolucent material;
- a first layer of radiopaque material overlaying the core layer or region of radiolucent material;
- an inner layer of radiolucent material at least partially overlaying the first layer of radiopaque material;
- a second layer of radiopaque material at least partially overlaying the inner layer of radiolucent material;
- and
- an outer layer of radiolucent material at least partially overlaying the second layer of radiopaque material, having a same or greater hardness as the second layer of radiopaque material.
An implantable medical device comprising structural element, the structural element comprising:
- a core region or layer of radiolucent material;
- a plurality of layers of radiopaque material overlaying the core region or layer of radiolucent material;
- and
- a plurality of outer layers of radiolucent material, with respective layers of radiolucent material layers overlaying respective layers of radiopaque material, the respective layers of radiolucent material having a same or greater hardness as the respective layers of radiopaque material.
