Artificial Sphincters

I know it's a little late in the design process, but I found the concept of artificial sphincters interesting enough to share with the class. The actual sphincter itself is just an inflatable balloon, much like a sphygmomanometer, used to measure blood pressure. The artificial sphincter is used mainly to replace sphincters that are not behaving normally in the body. For our device design, we are going to use very small sphincters to control flow of blood into our RVAD, in hopes that this gives us a way to slowly return a load to the heart, but is also reversible.
