Jack Erickson '15 under the guidance of Dr. S. Andy Sems '95 (alumus and surgeon at Mayo Clinic) and Dr. Michelle Clauss (Department of Engineering), designed a flexible, variable diameter reaming head to cut and clear debris from the interior canal of leg bones. The new design which provides the ability to vary the cutting diameter from 9 to 13mm eliminates the need to remove and re-insert increasingly larger fixed diameter cutting heads and will drastically reduce tissue injury and infection. In the fall of 2015, Erickson constructed and tested his design.
