Tracking Points On A Pacing Lead In A Beating Heart, Avinash Ramesh Varma
Tracking Points On A Pacing Lead In A Beating Heart, Avinash Ramesh Varma
Master's Theses
Heart failure is a common condition during which the pumping action of the heart is affected because the heart does not contract or relax properly. Heart failure affects about 5 million Americans, with 550,000 new cases diagnosed each year. Cardiac resynchronization therapy (CRT) is used to treat symptoms and other complications associated with a heart failure. While performing CRT, Implantation of a pacing lead in the left ventricle of the heart is a very challenging surgical procedure performed with fluoroscopy. The target location is often difficult to reach through the tortuous coronary venous anatomy, which varies greatly among individuals. Placement …
Design Of An Experimental Approach To Study The Growth Of Biofilm On Polymethylmethacrylate, Eireen S. Escalona
Design Of An Experimental Approach To Study The Growth Of Biofilm On Polymethylmethacrylate, Eireen S. Escalona
Biomedical Engineering
Biofilms are present in virtually every solid-liquid contact surface and are partially responsible for some diseases and water cleaning. They are a community of a variety of organisms that live symbiotically and are bound together by extracellular polymeric substances, or EPS. Biofilms go through five stages of development. These include initial and irreversible attachments, maturations I and II, and dispersion. In the dental world, biofilms are often associated with mouth infections including dental caries, gingivitis and periodontitis. Elderly denture wearers are susceptible to the pathogen-causing bacteria associated with these diseases, particularly those who have Alzheimer's disease or other forms of …
Finite Element Analysis Of The Nerve Cuff To Determine Usability And Stress Analysis During Regular Use, Vivek Machhi
Finite Element Analysis Of The Nerve Cuff To Determine Usability And Stress Analysis During Regular Use, Vivek Machhi
Biomedical Engineering
To determine the stress analysis on the Nerve Cuff by MicroProbes, a finite element analysis was conducted. A simplified model was created in Solid Works using the geometry of the basic model of the nerve cuff. The solid model was then imported into Abaqus and the appropriate materials, boundary conditions, and loads were designated. Initially a tensile test simulation was conducted using a tensile force of 2.87 Newtons. The maximum stress experienced with this tensile force was 8.225 MPa which was greater than the ultimate tensile strength of 5.5 MPa of Silicone. Both the actual tensile test and the tensile …
Modeling The Zimmer Fitmore And Ml Taper Implantation, Tyler Kazuo Franklin
Modeling The Zimmer Fitmore And Ml Taper Implantation, Tyler Kazuo Franklin
Master's Theses
With more young adults requiring total hip
arthroplasties the need for bone saving implants becomes
more important. The Zimmer Fitmore is a new bone saving
implant that utilizes an implantation technique that
reduces the damage to the muscle tissue allowing for
patients to have a short recovery time as well as a new
design that allows it to rest on the medial cortex. There
has been anecdotal evidence that this device leads to early
revision within six months of implantation due to failures
occurring in the medial cortex. The main goal of this
study was to computationally model the Zimmer …
Novel Approach To Junctional Bleeding: Tourniquet Device Proposal For Battlefield Hemorrhage Control, Kyle W. Cabaniss
Novel Approach To Junctional Bleeding: Tourniquet Device Proposal For Battlefield Hemorrhage Control, Kyle W. Cabaniss
Master's Theses
This study investigated possible solutions to the current wartime problem of junctional hemorrhaging, or massive traumatic hemorrhaging in non-tourinquetable areas such as the neck, groin, or armpit. Junctional hemorrhaging has been identified as a major contributor to potentially survivable deaths seen on the battlefield today and therefore is a priority for the U.S. armed and coalition forces (Kragh et al., 2011a; Bozeman, 2011). Common tourniquets today are standard issue and carried by soldiers in the military, but are limited to distal extremity trauma. As the battlefield has changes however, trauma has transformed from commonly seen gunshot wounds to more extreme …
A Microfluidic Pretreatment Isoelectric Focusing Dc-Field Assisted H-Filter For The Separation Of Charged Particles, Cameron Sean Carroll
A Microfluidic Pretreatment Isoelectric Focusing Dc-Field Assisted H-Filter For The Separation Of Charged Particles, Cameron Sean Carroll
Biomedical Engineering
Microfluidic devices are small portable diagnostic chips that allow for analysis of a biologic sample at relatively low cost. This makes them ideal for settings where a hospital is unavailable. The microfluidic pretreatment isoelectric focusing DC-field assisted H-filter is a device that allows for the separation of differently charged particles in a biologic sample. It does this by employing the concepts of diffusion, electrophoresis, and isoelectric focusing. This is perfect for isolation of a desired analyte or separation of waste from a sample in order to achieve better diagnostic results. The device was first modeled mathematically and visually using Comsol. …
Biomedical Advancements In Injury Recovery, Performance Enhancement, And Mechanical Assistance Applied To Athletics, Matthew Russell
Biomedical Advancements In Injury Recovery, Performance Enhancement, And Mechanical Assistance Applied To Athletics, Matthew Russell
Biomedical Engineering
Athletics is constantly changing, and athletes are continually getting bigger, faster, and stronger. At the same time, biomedical technology and innovation is rapidly developing. New methods of injury recovery, genetic enhancement, and prosthetic assistance are being assimilated into the athletic world. The up and coming athlete needs to be aware of all of the usable information around them. This project is an accumulation of some of the cutting edge advancements in those fields. Platelet Rich Plasma Injections, Frequency Specific Microcurrent Treatment, and Silk Polymer Anterior Cruciate Ligament Replacement are innovative new ways to treat common sports injuries. Performance enhancement has …
Investigating The Reproducibility Of The Current Bvm Protocol, Corey Gross
Investigating The Reproducibility Of The Current Bvm Protocol, Corey Gross
Biomedical Engineering
Coronary Artery Disease (CAD) is responsible for 1 death every minute in the US. Angioplasty with the implantation of stents is a common treatment method for CAD. Although there is a variety of stents currently on the market, there is still a need to develop new types for different pathologic conditions. Preliminary assessment of the physiological response to new stents is needed as they are being developed. The FDA approval process implemented today is a long, tedious path with a range of testing methods that include static in vitro testing and high-cost animal testing. Tissue engineered blood vessels have been …
Bacterial Growth On Metal And Non-Metal Surfaces In A Static Bioreactor, Rolan Yuk Loong Liong
Bacterial Growth On Metal And Non-Metal Surfaces In A Static Bioreactor, Rolan Yuk Loong Liong
Master's Theses
Research was conducted to observe bacterial growth on the surface of metals in a static bioreactor. Metal and non-metal samples were subjected to bacterial exposure (1 day and 9 days). The metal samples were surface treated prior to bacterial exposure. The microstructures of the surface treated samples were analyzed by optical microscopy. After exposure, the microstructures of the samples were analyzed by scanning electron microscopy (SEM). The analysis suggested that microbial attachment on the surface was related to the underlying microstructure of steel. The preferential attachment of microbes could potentially be influenced by cathodic and anodic regions created by the …
Effects Of Ovariectomy And Anatomical Location On Osteonal Encroachment In Adult Cortical Ovine Bone, Paige Brell Ryan
Effects Of Ovariectomy And Anatomical Location On Osteonal Encroachment In Adult Cortical Ovine Bone, Paige Brell Ryan
Master's Theses
The purpose of this study is to further quantify adult ovine ovariectomized bone for new remodeling characteristics to obtain a better understanding of how remodeling is occurring and the effectiveness of this animal model for the study of postmenopausal osteoporosis. Postmenopausal osteoporosis is a major health concern and animal models to test new treatment options are needed. The ovine model is a good option because the ewes undergo Haversian remodeling, are a large sized animal, and have a similar hormone profile to humans. Ewes, however, do not undergo a natural menopause, so an ovariectomy surgery was conducted in the sheep …
