Penn College’s Elizabeth A. Snedeker is on her way to becoming a biomedical engineer. The industrial design major devoted her senior project to redesigning a common, yet troublesome surgical instrument used for partial-knee replacements. Her design has impressed a prominent orthopedic surgeon, as well as the maker of the current extractor tool. “It was astounding to know that I had this opportunity and maybe I could do something with it,” said Snedeker, who graduated May 14 with a bachelor’s degree in industrial and human factors design. “Realistically, what I would like to do at the end of this is to have my design and have surgeons using my tool in order to make it more effective and efficient.”
