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

Quantification Of Blood Flow Velocity Using Color Sensing, Aditya Deepak Sanghani
Quantification Of Blood Flow Velocity Using Color Sensing, Aditya Deepak Sanghani
Master's Theses
Blood flow velocity is an important parameter that can give information on several pathologies including atherosclerosis, glaucoma, Raynaud’s phenomenon, and ischemic stroke [2,5,6,10]. Present techniques of measuring blood flow velocity involve expensive procedures such as Doppler echocardiography, Doppler ultrasound, and magnetic resonance imaging [11,12]. They cost from $8500-$20000. It is desired to find a low-cost yet equally effective solution for measuring blood flow velocity. This thesis has a goal of creating a proof of concept device for measuring blood flow velocity.
Finger blood flow velocity is investigated in this project. The close proximity to the skin of the finger’s arteries …

A Comprehensive Review Of The Food And Drug Administration, The 510(K) Application Process, And Fda Certification For A Diagnostic Device, Taylor Davis
Biomedical Engineering
The company G-Force CRC LLC is currently experiencing the dichotomy of the FDA's conflicting role right now as they begin to approach FDA approval. G-Force CRC LLC is a small medical device company headquartered in San Diego, CA. The owner of the company, Dr. Ian Purcell, is an Otoneurologist apart of Alvarado Hospital. His medical practice mainly deals with patients who have balance disorders and therefore the devices that he has developed over the last 6+ years are primarily used to assist in the diagnosis of those balance disorders. G-Force CRC LLC was officially created in the summer of 2013 …
Micro Electrostatic Actuation Of A Silicon Diaphragm, Matthew W. Samples
Micro Electrostatic Actuation Of A Silicon Diaphragm, Matthew W. Samples
Master's Theses
There are a number of applications, from hearing aids to microfluidic pumps, which utilize micro-scale actuating diaphragms. These MEMS (micro-electromechanical system) devices can be actuated by electrostatic forces, which utilize an induced electric field to pull two charged plates towards one another. Such devices were fabricated and electrostatic actuation of the diaphragms was performed to analyze its viability as a micro-speaker. The long-term performance of such products requires adequate diaphragm deflection to create audible pressure waves with relatively low maximum stresses to ensure a high cycle fatigue life. With these requirements, initial calculations and FEA (finite element analysis) were performed …
Analysis Of Particles Thorough The Aortic Arch During Transcatheter Aortic Valve Replacement, Andrew Joseph Janicki
Analysis Of Particles Thorough The Aortic Arch During Transcatheter Aortic Valve Replacement, Andrew Joseph Janicki
Master's Theses
Ischemia caused by particles becoming dislodged during transcatheter aortic valve replacement (TAVR) is a possible complication of TAVR. The particles that become dislodged can travel out of the aortic valve, into the aortic arch, and then into either the brachiocephalic artery, the left common carotid artery, the left subclavian artery or continue into the descending aorta. If the particles continue into the descending aorta it poses no risk of causing ischemia however if it travels into the other arteries then it increases the possibility of the particle causing an ischemic event. The goal of this study is to determine what …

Mechanical Engineering
In today’s world of medical innovation, regulations and requirements set by organizations such as the Food and Drug Administration (FDA), the International Organization for Standardization (ISO), and ASTM International (American Society for Testing and Materials) can inhibit rapid innovation by demanding rigorous testing of new designs. For arterial stents, the standard is that each design must be tested to simulate 10 years of life in an environment congruent to an in vivo environment. Endologix in Irvine, California develops and manufactures minimally invasive treatments for aortic diseases, with a focus on stent grafts for the treatment of abdominal aortic aneurysms (AAA). …
Design And Fabrication Techniques Of Devices For Embedded Power Active Contact Lens, Errol Heradio Leon
Design And Fabrication Techniques Of Devices For Embedded Power Active Contact Lens, Errol Heradio Leon
Master's Theses
This thesis designed and fabricated various devices that were interfaced to an IC for an active contact lens that notifies the user of an event by detection of an external wireless signal. The contact lens consisted of an embedded antenna providing communication with a 2.4GHz system, as well as inductive charging at an operating frequency of 13.56 MHz. The lens utilized a CBC005 5µAh thin film battery by Cymbet and a manufactured graphene super capacitor as a power source. The custom integrated circuit (IC) was designed using the On Semiconductor CMOS C5 0.6 µm process to manage …

Evaluating The Effectiveness Of Cranial Molding For Treatment Of Positional Plagiocephaly Using Finite Element Analysis, Maziyar Keshtgar
Master's Theses
Since the advent of recommendations for placing infants in the supine position during sleep to reduce the incidence of sudden infant death syndrome, clinicians have noted an increase in the frequency of cranial asymmetry due to deformation of suture sections of the infants’ skulls as a result of constant concentrated stress in one area at the back of their head. This specific form of cranial deformation is known as positional plagiocephaly and its rate of occurrence has increased from 0.3% in 8.2% within the past 30 years.
Current treatments and methodologies for preventing and correcting positional plagiocephaly such as stretching …
