The Final Product

The Final design removes the box and the heater from the CAD concept. The idea of heating the water is that there would be a large change in the characteristics of the material. During the material testing the materials were tested in open air at room temperature and submerged in 37-degree C water. The final material had less than a 5% change in modulus of elasticity and there for was removed from design. The box for holding the aneurysm body was built, but was too small to properly hold the tubing and caused the model to lift. The final cart incorporated a third shelf that was used to display the projects achievements and hold the water reservoir. The GUI controls the pump while displaying a live graph of the pressure in the aneurysm. The pump is able to run a continuous flow function, from 0- 136 ml/s via the slider bar on the screen and was validated by a flow meter and displayed on the screen. The pump can then be converted to a pulsatile where the slider bar controls the BPM of the pulsatile flow and the rate is displayed on the screen. Clamps were used to increase the pressure in the system and introducers were used to deploy a stent graft into the system. The team was given $3000 and by the end of the project the team had a remaining balance of $318.30
