Expandable Urinary Stent
The goal of this project is to simulate urinary stent prototypes using the finite element method in order to identify the optimal design. This group’s urinary stent is novel, because it has a greatly increased axial compliance when compared to current urinary stents. The increase in axial compliance is achieved by patterning holes on the distal and proximal ends of the stent. Increasing axial compliance is hypothesized to significantly reduce patient discomfort associated with movement and breathing.
Specifically, the researchers are using MSI resources to model and identify the optimal size, shape, distribution, and quantity of holes that will provide the required compliance in the most efficient manner.
