OUR TEAM Sarah Brady River Rodriquez Kayla Culhane Adriane Cana Sevy Perez LAB 2 WRITE-UP Device Image and Description Our prototype is an atherectomy plaque removal device. It is designed to mimic the lenticels on a mangrove tree that act as raised pores and open to move external 'gas' or liquid internally. The many raised pores on the surface of our device have holes in the center that open and close to attract soft plaque. Our device aims to decrease restenosis rates by more effectively and safely removing plaque than other atherectomy device. Technical and Clinical Feasibility Technical Feasibility The device will need a catheter (the standard arterial catheter) attached to a needle (20-gauge for adults, 22-gauge for children) specifically for insertion. To guide it, the device will need a guide wire that the doctor will use to move the device. A gel tip that is disposable made of some sort of silica gel will be used to make guiding the device much easier and a rubber or gel coating on the device itself will reduce the pain of the procedure. The device itself will be made of an iron alloy with a filtration system inside to capture different types of plaque. The filtration system will include mangrove-like pores that open and close, trapping the plaques inside. Building the filtration system could become an issue because it has to be leveled properly so the less solid plaque does not escape the device through the solid’s filter. There also has to be a way that the calcium is broken down enough to be held inside of the device. We must find a way to open and close the filters just enough that the initial plaque is removed from the artery and held in the device while removing other remaining plaques. Plaque could leak from the device, completely making the procedure completely obsolete. It may be difficult to build a filtration system that has pores that open and close on its own.
