This is the final paper for my spring 2010 design team. We worked with our client, Amish Raval, who is a cardiologist at the University of Wisconsin Hospital. Dr. Raval is researching the possibility of using stem cells to restore function to cardiac muscle after myocardial infarction. He came to us with the problem of creating a more consistent trial environment for his study. He currently injects the stem cells into animals with a syringe by hand. However, results are not completely reliable due to human variability in injecting a 200uL injection over 30s. Thus he asked us to produce a device that would be able to hold the syringe and catheter that he currently uses and create an injection at a constant pressure to increase cell viability.
