Abstract/Summary
In order to better understand Type IV endoleaks (“blush”), the Cal Poly Senior Project team GraftTest has developed a blush evaluation system able to mimic several of the aorta’s environmental parameters. Capable of both pressure and flow rate control, this bench top system accommodates Medtronic’s wide range of abdominal and thoracic aortic stent grafts. Having researched endoleaks, stent grafts, and numerous other factors affecting stent graft blush, a system was developed with the aim of assessing and comparing the performance of Medtronic’s stent grafts with regard to blush. Furthermore, this system has been designed to provide reliable and repeatable results in accordance with the formal engineering design process. Our mark I design proposal utilizes a combination of measurements, including: water weight, flow rate, and pressure in order to qualitatively measure stent blush resistance values. In addition our design allows for realistic visualization of blush by submerging the stent graft in water and allowing for dye injection into the stent graft.
