Prosthetic Foot Shell, Ql+, Kathryn Victoria Versteeg, Jackson A. Tucker, Ethan William Frey
Mechanical Engineering
This final design review includes an overview of our project and the steps we have taken to create our final product. We discuss the background research conducted, including various products like the foot shell we are trying to design and its related patents, along with similar past senior projects. As our product is considered a medical device, there are also certain standards that we must comply with. After determining our problem statement, we established what we believe to be the wants and needs of our user. These wants and needs were converted into specifications for our design, with durability as …
Breathe Easy: A More Efficient Way To Avoid Tracheostomy Airway Blockages, Kathleen Swanson, Katelynn Russ, Olivia Zimmerman
Breathe Easy: A More Efficient Way To Avoid Tracheostomy Airway Blockages, Kathleen Swanson, Katelynn Russ, Olivia Zimmerman
Honors Theses
Over 100,000 people receive tracheostomies each year in the United States when mechanical ventilation is needed for longer than 48 hours, a patient has a chronically obstructed airway, or the patient is unable to protect their airway from aspiration. A tracheostomy is inserted into a patient’s trachea in order to modify their airway through a tracheotomy procedure. A tracheostomy tube alters the natural lining of an airway which normally has a 5-50 μm thick layer of mucus. An airway with a tracheostomy tube produces more mucus than the average airway of a healthy person, and it also limits the patient’s …

Septal Closure Device, Olivia N. Welch, Hillal H. Jarrar, Kai Harrison
Biomedical Engineering
The septal closure device was designed to seal defects in the atrial septum. To fully seal an atrial defect, the device was designed to consist of two circular seals to cover the defect in both the right and left atria, attached with a central rod. The materials were chosen for compressibility (for ease of insertion), biocompatibility, and tissue ingrowth. A CAD model was drafted in SolidWorks. Key customer requirements include ease of implantation (specifications: adjustable sizing and clear directions for use), physician controlled (specifications: short implantation time and compatibility with current catheter/scope techniques), and a long lifetime (specifications: materials that …
