Electro-Muscle-To-Muscle Transfer, Hailey Quinn Casino, Jake Keola Javier, Samuel Joseph Borda, Charlotte Amalie Anderson
Biomedical Engineering
The Electro Muscle to Muscle Transfer (EMMT) system will entail designing, manufacturing, and providing a wearable device that stimulates paralyzed muscles in the hand by sampling and amplifying muscles from the forearm. With further development, the system may be capable of using different muscle inputs other than the forearm muscles along with different stimulated muscle outputs other than the hand. The system functions as a rehabilitative device for spinal cord injuries, irreparable nerve loss and/or damage, and improper neuromuscular function. It is not for total treatment nor for curing of the disabilities listed above but to alleviate the side effects …

The Tierni Resistance Training System, Michael J. Hansen, Abigail M. Youngblood, Gabriel M. Johnson
Biomedical Engineering
The purpose of the Tierni Resistance Training System project was to design and construct functional workout apparel that has built-in resistance. For this product, the key customer requirements we set out to address were most importantly material comfort and functionality, followed by stylishness, lack of latex, safety for injured and uninjured users, and washer safety. To meet these customer requirements, we started by researching current resistance training technology, and used the findings as a springboard for our own design development. After initial brainstorming, engineering specifications were generated based on the customer requirements. These specifications revolved around the thermal insulation, pressure, …

Non-Invasive Peripheral Venous And Arterial Line Air Detector For Embolization Prevention, Alexandria Kwong, Kevin Shu, Dylan Meinster
Biomedical Engineering
The scope of this project includes designing a non-invasive bubble detector for peripheral venous and arterial lines. For minimally invasive cardiac procedures, arterial and venous access is necessary for these procedures as is constant flow through the tubing to prevent clotting and to administer drugs. Air bubbles are common in these lines and can be consequential if enough air is introduced into the human system. Air embolisms are the most common and relevant issues during these procedures. The goal of this device is to create an attachable detector for air bubbles in saline that can also terminate flow and alert …

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 …

Opendrop Elisa: Surface Development For Digital Microfluidic Elisa Testing, Michaela Q. Mead, Madeline G. Jackson, Jacob G. Taylor
Biomedical Engineering
This project aimed to develop a process to create a hydrophobic coating with capture antibodies attached. This process was developed in an attempt to create a digital microfluidic platform upon which an enzyme-linked immunosorbent assay (ELISA) could be run, indicated for clinicians and educators in low-resource settings. Four requirements dictated the course of the design process: 1) the contact angle with water of the hydrophobic layer must be greater than 90º, 2) the colorimetric response of a positive ELISA result on our platform must be at least 85% of that run on polystyrene with the same result, 3) the platform …

Prosthetic Thumb, Allison M. Sigdestad, Sahil Sharma, Cale Foreman
Prosthetic Thumb, Allison M. Sigdestad, Sahil Sharma, Cale Foreman
Biomedical Engineering
The Prosthetic Thumb Project is a senior design project completed by Biomedical Engineering Undergraduate students at California Polytechnic State University. This senior design project is aimed at designing a prosthetic thumb for a Cal Poly Pomona student who lost their thumb in an accident last year. The patient has ultimately lost between 30-40% of functionality of his left hand, and so we would like to give him that mobility back. Originally, the patient was worried about having a prosthesis, and wanted something more stagnant that would resemble the look of the thumb he lost. However, after working with him, we …

Left Atrial Appendage Printing Process, Areli Reyes, Brandon James Mukai, Mia Noelle Von Knorring
Biomedical Engineering
The left atrial appendage senior design team aims to assist in closing off the left atrial appendage that is susceptible to coagulation due to non-valvular atrial fibrillation. Coagulation in the left atrial appendage (LAA) can be life threatening as it can lead to a stroke. Dr. Chris Porterfield performs a procedure that uses the Boston Scientific Watchman to close the appendage. He finds that sizing the Watchman properly is difficult with limited visuals from live CT scans. He proposed converting the CT scans into a 3D printed model of the left atrial appendage and left atrium so he can visually …

Mechanisms Of Reduced Vascular Tone Following Arteriogenesis Induced By Femoral Artery Ligation, Christopher Hatch
Mechanisms Of Reduced Vascular Tone Following Arteriogenesis Induced By Femoral Artery Ligation, Christopher Hatch
Biomedical Engineering
The presence of a developed, native collateral network can decrease the severity of ischemic injury proceeding arterial occlusion. The collateral network must under arteriogenesis to enlarge and increase blood flow to the ischemic region. Although there has been tremendous effort attempting to understand the mechanisms of arteriogenesis, no therapies have been successful in improving patient outcome. To better understand the mechanisms involved in arteriogenesis, the effect of nitric oxide production, myogenic tone, and a-adrenergic receptors were evaluated as these have been identified as playing an important role in vascular injury. Arteriogenesis was induced by ligating the femoral artery between the …

Cooking Hand Multi-Tool, Amanda D. Meares, Amy H. Wilson, Ethan G. Littlejohn, Duania A. Evans
Biomedical Engineering
The purpose of this project was to devise a solution for Jorge Segura, a US Marine who was wounded in Afghanistan and had to have his non-dominant arm amputated above the elbow. His current prosthetic attachments are not suited to cooking tasks, so he needed a way to cook more effectively with either prosthetic attachments or accessibility devices. The main tasks that he needed help with was holding down food on cutting boards and stabilizing pots, pans, and bowls especially when stirring. After background research, exploring commercially available devices, and talking with our challenger, our solution was to design three …
