New Force Transducer For Mitral Valve Chordae Tendinea, Joseph Berryman
New Force Transducer For Mitral Valve Chordae Tendinea, Joseph Berryman
Biomedical Engineering Undergraduate Honors Theses
In order to inform the future of mitral valve repair and replacement, more investigation into the mechanics of the sub-valvular structure is needed. Understanding the roles of each chord during valve closure requires a sensor capable of detecting these small forces with enough sensitivity to determine the characteristics of each of the chordal types. The focus of the cantilever force transducer is to maximize this sensitivity while also minimizing the invasiveness of the sensor on the overall function of the chord. The design utilizes flexible yet strong 3D printed resin and cantilever arms to improve the strain exerted on a …
Upper Extremity Mobility Device, Timothy J. Grassi, Jacob R. Miller
Upper Extremity Mobility Device, Timothy J. Grassi, Jacob R. Miller
Williams Honors College, Honors Research Projects
The goal of this project was to evaluate a clinical problem, explore possible solutions, and produce a functioning prototype that would conform to all the established guidelines and requirements. The project focused on developing an upper extremity mobility device for a singular client with limited muscle activity in his arms due to childhood polio. Our design process was governed by an adapted form of the FDA Design Control Process, 21 CFR 820.30 [1]. The outcome of this project was a functioning prototype that utilized the concept of a motorized pulley system remote controlled using a key fob. This research project …
Mechanical Characterization Of Carbon Fiber And Thermoplastic Ankle Foot Orthoses, Amanda Wach
Mechanical Characterization Of Carbon Fiber And Thermoplastic Ankle Foot Orthoses, Amanda Wach
Master's Theses (2009 -)
The needs of an increasingly young and active orthotic patient population has led to advancements in ankle foot orthosis (AFO) design and materials to enable higher function. The Intrepid Dynamic Exoskeletal Orthosis (IDEO) is a custom energy-storing carbon fiber AFO that has demonstrated improved clinical function, allowing patients to return to high-intensity activities such as sports and military service. An improved understanding of AFO mechanical function will aid prescription and fitting, as well as assist in design modifications for different patient populations. This study investigated the mechanical properties of AFOs, specifically structural stiffness, rotational motion, and strut deflection, to discern …
