PhD Position (m/f/d) Development of a Bioabsorbable Urethral Stent Device for the Treatment of Urinary Disease

Project Description

Traditional permanent metallic stents pose long-term challenges in the treatment of urinary disease, such as the need for removal, potential complications, and interference with imaging. A bioabsorbable urethral stent offers a temporary solution by providing structural support during the healing process. Unlike permanent stents, bioabsorbable stents gradually dissolve over time, eliminating the need for removal procedures. This minimizes the risk of long-term complications, facilitates the natural healing of the urethra, and allows for improved diagnostic imaging when necessary.

This project will develop a high strength ureteral stent for the treatment of urinary disease from either preferred Magnesium or Zinc alloy.

The objectives of this project are:

1. Establish Design I/O matrix for ureteral device

2. Development of design concepts for target design of ureteral stent from either preferred Mg & Zn alloy through finite element simulation using Abaqus simulation software.

3. Production of early design prototypes for preliminary testing to evaluate functional mechanical behaviour and corrosion performance 4. Design optimisation and verification of devices as per ISO 25539-2 (e.g. radial force, bending behaviour, crush resistance, crimpability) and decreased encrustation score (<25).

This project would suit a candidate with an academic qualification in Mechanical, Biomedical or Materials Engineering (or related disciplines), and previous experience in experimental characterisation or computational modelling of medical devices desirable.
