Aneurysm/Graft/Foam Animation
Compliant Silicone Aneurysm Model
Pulse Model
Project/Role:
Complex abdominal aortic aneurysm (AAA) model used for testing in the absence of any true animal study. Team attempting to find a delivery device/foam combination that will successfully surround and support stent graft while blocking collateral flow within aneurysm.
Action:
Used model to determine deployment system and formulation behaviors in an anatomically correct situation. Collected key data during test trials using a custom DAQ program used in conjunction with pressure transducers, ultrasonic flow sensors, and force sensors.
Results:
Personally ran 75 pulse model deployments, and determined a system that produced repeatable results of desired outcomes. Test results were a large contributor to obtaining further project funding.
Compliant Silicone Aneurysm Model
Prototyped Tubing/Balloon System
Stent Graft Impingement Test Design
Project/Role:
During our pulse model testing, different formulations/delivery devices can affect the impingement of the stent graft drastically, but we had no way to quantifiably differentiate “impinged” from "not-impinged”.
Action:
Designed and prototyped tubing/balloon system to block stent graft legs after placement within the aneurysm with only found-in-lab resources. Bypouring water into the stent before and after the formulation depolyment, an "impinged" volume can be derived. Completed and documented multiple tests in order to establish a standard test method and reproducibility data.
Results:
Established a reliable way to determine the change in volume within the stent graft giving the team the ability to quantify how different viscosity formulations/delivery devices impinge the flow through the stent graft.
