Hand Tremor Stabilizer, Krishna Sai Bathini, Ryan Herrmann, Madeleine A. Beaupre Mar 2024

Hand Tremor Stabilizer, Krishna Sai Bathini, Ryan Herrmann, Madeleine A. Beaupre

Biomedical Engineering

The Hand Tremor Stabilizer project represents a significant advancement in assistive device technology, aimed at improving the lives of individuals affected by hand tremors due to conditions such as essential tremor or Parkinson's disease. Throughout the design process, our team engaged in a comprehensive approach that included rapid prototyping, iterative testing, and direct feedback collection from potential users. This process was instrumental in refining the device to meet specific user needs effectively.

Key customer requirements that guided the design of the Hand Tremor Stabilizer included ease of use, portability, washability, accuracy of motion control, comfortable grip, breathability, a natural feel …


Left Atrial Model, Borna Sobati, Sarah Porello, Tess Pate May 2019

Left Atrial Model, Borna Sobati, Sarah Porello, Tess Pate

Biomedical Engineering

The objective is to produce an electrophysiological model of an adult human left atrium. This model will be used to test mapping probe catheters used for locating cardiac arrhythmias against current technology used in practice. Dr. Chris Porterfield requested this model and other physicians or probe catheter manufacturers may also use this product in the future. Dr. Porterfield also discussed the possibility of future senior project groups using the model as a bench test for designing new catheter tips. The model will precisely simulate electrical behaviors of the heart in normal as well as arrhythmic conditions. Ideally, the model will …


The Effect Of Neurostimulation On Ischemic Pain And Methods Of Assessing Pain, Kaylee Keck Dec 2015

The Effect Of Neurostimulation On Ischemic Pain And Methods Of Assessing Pain, Kaylee Keck

Biomedical Engineering

Peripheral arterial disease (PAD) impacts approximately eight million people in the United States [1]. Disease progression leads to chronic ischemic pain, hindering quality of life. Pharmaceuticals are a typical treatment for pain associated with PAD; but as few as 30% of patients have a significant reduction of pain (≥50%) [2].

Neurostimulation is commonly used as a treatment for various diseases and injuries, including Parkinson’s disease and sports-related back and knee injuries [2]. The objective of the study was to explore neurostimulation and its effect on pain and paresthesia for a model of acute peripheral ischemia in young college students.

Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian Jun 2014

Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian

Biomedical Engineering

Peripheral arterial occlusive disease (PAOD) occurs due to the build up of atherosclerotic plaque and reduces blood flow to cause chronic ischemia. Patients with PAOD may experience intermittent claudication, or the pain in limb skeletal muscles due to a decease in blood flow. Collateral arteries can act as a natural bypass and improve blood flow to hypoxic tissue by creating an alternate route for blood to flow, but not all patients with PAOD have pre-existing collateral networks. Animal studies indicate that tissues without pre-existing collateral networks can form de novo collaterals from capillaries following occlusion of a feed artery. Unfortunately, …
