Project Description
Scope
The Calcified Vessel Model project team has been tasked with designing and manufacturing twelve vessel models intended for simulation and medical testing. These models must accurately replicate the anatomy of human blood vessels and the physiological symptoms of peripheral arterial disease (PAD), including blood vessel material properties and blood flow characteristics.
The client, Gore & Associates, plans to use these models to evaluate the deployment of their vascular interventional devices. Therefore, it is essential for the team to ensure that the models accurately replicate human artery anatomies and physiological conditions of PAD.
"The scope of the project is to design, build, and test a replicable model of calcified lesions in the Peripheral Arterial System for the deployment of peripheral vascular interventional devices under simulated use conditions, using non-biological materials." - Project Outline, Gore & Associates
Location
Project: Northern Arizona University - Flagstaff, AZ
Client: Gore & Associates - Flagstaff, AZ
Constraints
This project must comply with all applicable OSHA and ANSI standards, as well as Gore & Associates standards for quality.
The final product should be capable of functioning safely at temperatures and pressures typically encountered within a human artery with peripheral arterial disease.
The lesion must accurately simulate calcification occurring in blood vessels, without using biological materials.
Tasks
Tasks from the project outline:
Develop, justify, and characterize the following attributes (recommended but not limited to):

Selected for prototyping only
corn syrup mixture.
Schedule & Budget
Schedule Sheet
The Gantt chart used by the team to plan their semester and track their progress. It outlines all project tasks, sub-tasks, deliverables, and milestones in chronological order.
Budget Sheet
The current state of the team's budget at this point in the semester. It outlines all project expenses, including procurement, prototyping, and building the final design.
Final Design
Calcified Vessel Model CAD Assembly
The CAD assembly of the final calcified vessel model design, created by the team in SolidWorks.
Consists of the calcified lesion model, vessel model, tubing, peristaltic pump, pressure transducers, fluid reservoir, roller cart, and computer for data collection (the blood analog is omitted).
