Axel Delakowski
Axel was in charge of Solidworks CAD design. This included the development of the stent cell pattern and geometry as well as additional modeling for computational and physical testing. Axel collaborated with Calvin to develop models for use in FEA testing, Kristen to import the stent and vessel geometry into CFD, and Hannah to design a flow chamber for benchtop testing. As the leader, Axel was in charge of group communication between members and advisors. This included running meetings, optimizing workflow, and mediating important decision-making.
Calvin Okulicz
Calvin was in charge of all Finite Element Analyses of the stent across all diameters as well as other physiological parameters that would affect stent performance and safety. Calvin worked with Hannah to set thresholds for acceptable stresses on the vessel, as well as the other team members on mechanical-related issues. Calvin was also in charge of developing the project timeline and development to ensure the project was completed in time.
Kristen Zozulia
Kristen was responsible for creating a stent pulmonary model to determine the effects of the stent on fluid flow. This involved performing literature reviews to gather flow parameters in the MPA, LPA, and RPA. Kristen was in charge of running CFD simulations to determine fluid parameters and stresses that are experienced by the stent. This is necessary for stent design verification. In addition, Kristen ran a time-dependent case with the pulmonary artery model with a power-law hemolysis model to aid in the validation activity for the requirement surrounding biocompatibility. Kristen was also responsible for the budget and organizing purchases.
Hannah Morgan
Hannah was in charge of biomaterials and in vitro testing for the stent. This included developing design requirements and specifications based on vessel and tissue physiology, selecting materials with the appropriate characteristics, and using literature reviews to examine the potential in vivo responses to the device such as tissue ingrowth and thrombosis. Hannah developed a benchtop model of the stented vessel for in vitro testing, working with Axel to design and manufacture a flow chamber and creating a recirculating flow loop, and performed in vitro testing of the device. Hannah was in charge of creating and maintaining the team’s website, keeping meeting minutes, and organizing key documentation for the project.
