P2a: Thin film flow-diverter stents based on superelastic shape memory alloys (E. Quandt)

Flow diverter stents made of superelastic TiNi thin films will be fabricated using thin film technology and MEMS processes based on FEM calculations. The work will consist of four major parts:

1.) Development of a finite element model (FEM) in order to describe flow diverter stents made of superelastic TiNi thin films including their cripmping behavior.

2.) Fabrication of flow diverter stents made of superelastic TiNi thin films using magnetron sputtering, photolithography and etching techniques.

3.) Characterization of the microstructure and the functional properties including fatigue.

4.) In collaboration with project P2b (O. Jansen): Fluid dynamic characterization of the different flow diverter stent designs
