PhD Position (m/f/d) Development of a Bioabsorbable Mg/Zn Flow-diverting Stent for Treatment of Aneurysms

Project Description

The objectives of this PhD-project are:

1. Establish Design I/O matrix and investigate design concepts for a wire braided flow diverter stent using Magnesium or Zinc alloy wires, optionally with additional braids comprising non-absorbable alloys (NiTi), considering braid angle, wire thickness and mesh density.

2. Production of early prototypes for preliminary testing to characterise degradation kinetics.

3. Design optimisation and verification of devices according to ISO 25539-2 (i.e., radial force, bending behaviour, crush resistance, crimpability) and in a neurovasculature model.

4. Successful production of late-stage prototypes for preclinical (animal) testing using wires of < 0.1 mm in diameter.
