Redesigned Endoscopic Bite Block For Geriatric Patients, Kayla Fisher, Katherine Gregory, Owen Corey
Honors Theses
Esophagogastroduodenoscopy (EGD) is an examination of the interior of the esophagus, stomach, and beginning of the small intestine. Upper gastrointestinal (GI) endoscopies are used to diagnose ulcers, cancers, and gastrointestinal tract diseases, as well as to collect biopsy samples. In 2008, over 55 million procedures were performed with GI endoscopic devices [1]. In order to keep the mouth propped open during this procedure, a bite block is used. This bite block ensures that the patient will not bite down on the endoscope during the procedure. Geriatric patients are more likely to have poor dental health due to medications they take, …

Electronic Theses and Dissertations
With the possibility of longer ventures into space, NASA will face many new medical challenges. The ability to surgically treat trauma and other disorders in reduced gravity requires reliable wound access, containment, and visualization. In collaboration with Carnegie Mellon University, the University of Louisville is currently developing the AISS (Aqueous Immersion Surgical System) to increase efficiency and control of the operative field in space-based surgeries. Reliable wound access and containment is achieved by placing a transparent wound-isolation dome securely over the wound-site and pressurizing it with a saline solution. Leak-free trocars provide access ports for various surgical instruments. This system …

Analysis Of Vocal Fold Kinematics Using High Speed Video, Harikrishnan Unnikrishnan
Theses and Dissertations--Electrical and Computer Engineering
Vocal folds are the twin in-folding of the mucous membrane stretched horizontally across the larynx. They vibrate modulating the constant air flow initiated from the lungs. The pulsating pressure wave blowing through the glottis is thus the source for voiced speech production. Study of vocal fold dynamics during voicing are critical for the treatment of voice pathologies. Since the vocal folds move at 100 - 350 cycles per second, their visual inspection is currently done by strobosocopy which merges information from multiple cycles to present an apparent motion. High Speed Digital Laryngeal Imaging(HSDLI) with a temporal resolution of up to …
