Zimmer Inc.

Project Overview

Mid-clavicular fractures are one of the most common injuries to the human skeleton. The task for this project is to create a clavicle bone-plate for Zimmer’s Trauma Division. Designs were justified based on biomechanical modeling of stresses performed in both the MATLAB and Abaqus environments. The final plate design was shown to balance clavicular stresses due to the biomechanical loading of daily activities, as well as provide structural support for various fracture geometries in the clavicle.

The Development of a Hydrophilic/ Hydrophobic Interface

The Development of a Hydrophilic/ Hydrophobic Interface

Team Members

Traci Billings, Biomedical Engineering and Anthropology; Hilary Aho and Henry Durnwald, Biomedical Engineering/Materials Science and Engineering; and Thomas Hurley and Julia Osborne, Biomedical Engineering

Advisor

Dr. Megan Frost

Sponsor

Department of Biomedical Engineering

Project Overview

We are fabricating a polymer layer to interface with hydrophilic and hydrophobic materials simultaneously. This will be accomplished through the production of a coating that can be placed over a base layer, such as polypropylene, silicon rubber, or stainless steel, that will allow for good adhesion with a collagen layer, which will in turn promote cell attachment and growth. A potential benefit of this technology is to control biological response to artificial materials used to fabricate implanted devices.

Portage Health

Project Overview

The goal is to design and develop a sound-level alarm to be incorporated at Portage Health in Hancock. The objective is to alert the main focus group when sound levels reach a decibel level over a set threshold and remind the focus group to quiet down to benefit patient health. The design needs to accommodate for a multifunctional interface to give the user an opportunity to individually customize each unit by allowing for data logging, variable threshold settings, visible alarm, and an appropriate display for changing settings.

Boston Scientific

Project Overview

Boston Scientific is a leader in the development of therapies and implantable devices used to treat cardiovascular disorders, cardiac arrhythmias(abnormal heart rhythms), sudden cardiac arrest, heart failure, and vascular system issues. The focus of this project is to develop a wireless device which provides feedback for assessing in vivo conditions for different implant situations..

Boston Scientific

Project Overview

The next generation of drug-eluting stents may contain drug-releasing biodegradable polymer coatings. However, the biodegradation rates and behavior of these polymer coatings will first need to be tailored to meet the needs of diseased arteries. As an improvement over existing methods, we have developed low-cost, simplified, and time-effective methods for characterizing the degradation behavior of different polymers. These parallel in vitro and in vivo methods exploit the properties of fluorescent molecules and utilize simple implant geometries to characterize degradation rates and behavior.
