Breech Baby, Madison Kaufman, Cassidy Allen, Lilian Mills

Williams Honors College, Honors Research Projects

Our project aims to develop a non-invasive device to assist in turning breech babies to a head down position before delivery. Pregnant women facing breech presentations often need safe and effective solutions, yet current options like external cephalic version (ECV), maternal positioning techniques, and cesarean sections can present challenges. Key barriers include variability in maternal and fetal anatomy, patient comfort, compliance, and training for healthcare providers, along with cost and insurance concerns.

Our innovative device will address these issues by providing clear guidance and support throughout the process. It will prioritize minimizing discomfort and risk, ensuring adaptability for various stages …

Part I - Ai And Data As Medical Devices, W. Nicholson Price Ii

Other Publications

It may seem counterintuitive to open a book on medical devices with chapters on software and data, but these are the frontiers of new medical device regulation and law. Physical devices are still crucial to medicine, but they – and medical practice as a whole – are embedded in and permeated by networks of software and caches of data. Those software systems are often mindbogglingly complex and largely inscrutable, involving artificial intelligence and machine learning. Ensuring that such software works effectively and safely remains a substantial challenge for regulators and policymakers. Each of the three chapters in this part examines …

Development Of An Intraperitoneal Catheter Placement Device For Use On The Battlefield, Riley Reynolds

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

The objective of this project was to simplify peritoneal cavity access so an Airforce field medic can safely infuse oxygen microbubbles (OMBs) into the intraperitoneal space for the emergency treatment of hypoxia due to lung damage. To solve this problem, we created an intraperitoneal catheter placement device for use on the battlefield. The three common methods and some of the most common devices for peritoneal cavity access were reviewed. Injury frequencies for each of the three methods were analyzed. The results showed that each of the access techniques gives a similar rate of iatrogenic injury.

The battlefield conditions where the …

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 …

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 …

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 …

Slit Lamp Ophthalmoscope Redesign, Michael Hostetler, Austin Mattmiller, Alexis Brewer

Biomedical Engineering

The slit lamp ophthalmoscope is used by ophthalmologists for diagnosis of pathologies in the eye. The device is used for identifying ocular diseases or indications of other possible systemic diseases to treat them before the diseases progress. Redesign of the ergonomics and adjustment mechanisms of the slit lamp ophthalmoscope will attempt to improve the compatibility of the device across a greater variety of patients. The wider headrest tower of 12.75 inches, the wider table cutout of 12 inches, and the 12 inches of extension of the headrest tower creates a better ergonomic fit for the patient and doctor. The wider …

Design Of Medical Devices For Diagnostics In The Gastrointestinal System, Charles R. Welch

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

This thesis presents the design, controls, and testing of two systems: a novel colonoscope locomotion design for diagnostics, and a biosensor capsule that implants a sensor in the small intestine. Each system requires special design considerations for use in the gastrointestinal system.

Colonoscopy procedures are recommended as a screening for colon cancer and related conditions after the age of 50. The need for an improved colonoscope that reduces the colonoscopy time and patient discomfort is apparent. The semi-autonomous device presented here could likely reduce the colonoscopy procedure time by allowing the physician to focus more on the diagnosis and less …

Foley Catheter Priming Device, Melissa A. Boswell, Landon Davis, Renee Horn, Tyler Grubb, Jason Green

Williams Honors College, Honors Research Projects

A lack of a pressure gradient throughout the catheter prevents urine flow from the bladder and through catheter system in a condition referred to as “air-lock.” The purpose of this project was to design a device that could be utilized by person with a catheter faced with the problem of air-lock to restore urine flow and normal functioning of the catheter system. After a prototype was created, the device was put through a series of tests to insure proper functioning, absence of leakage, and durability. The device created can be added in-line with the catheter system, inconspicuously under the user’s …
