Aspirus Keweenaw
Project Overview
Our team is working with Aspirus Keweenaw to implement a system to automatically and continuously monitor temperatures and humidity in hospital labs and equipment in order to decrease labor costs and the unnecessary loss of reagents and materials. The system must notify appropriate personnel when temperatures are too far out of range to limit the amount of reagents needing to be discarded.
Delivery Tool for a Leadless Pacemaker

Medtronic Inc.
Project Overview
The design problem presented by Medtronic consists of modifying a delivery tool currently used during the deployment of the Micra leadless pacemaker. The modified tool must satisfy two independent functional requirements: 1.) guide the device catheter through the atrium and ventricle and 2.) unsheath the pacemaker to expose the implantation tines.
Fixation of a Cardiac Leadless Pacemaker

Boston Scientific
Project Overview
Boston Scientific tasked our team with designing, building, and testing a fixation mechanism for a leadless pacing device. This wireless pacemaker is to be attached on the interior endocardial surface of the right ventricle of the heart. The mechanism must stay fixated without risking device detachment, which could cause embolization and pulmonary infarction, and it must be removable at the end of the service life. The fixation mechanism can neither add to the diameter of the device nor take up vital space inside the pacemaker that could be used as battery space.
Personal Ultraviolet Radiation Monitor

Project Overview
A senior design team from last year developed a photosensitive patch that tells users when they’ve absorbed the amount of radiation that causes sunburn. Our team was tasked with finding a treatment for the patch, which would better simulate the behavior of skin. This treatment is meant to mimic the absorption of sunscreen into skin.
Pro-Healing Arterial Graft Scaffold Design

Project Overview
This project aims to construct a vascular graft specifically for use in small-diameter arteries. Narrower vasculature generally has harsher conditions, so viable grafts are more difficult to construct. This graft uses decellularized biologic tissue called elastic lamina to induce a nonimmunogenic and nonthrombogenic effect in the body. The elastic lamina layer is supported by a polymer scaffold around its exterior. A variety of polymers were analyzed for biocompatibility and sufficient structural properties. The resulting vessel has been tested for mechanical integrity and also implanted in a rat model to test for biological viability.

Portage Health
Project Overview
Patients find it difficult to maintain restful sleep while at the hospital due to excessive noise. Previous Senior Design teams have created a device to detect noise levels and produce a visual signal when they have exceeded a predetermined threshold. The design will be evaluated via clinical trials performed at Portage Health. With the information gained from the experiment, we will evaluate the effectiveness of the design in reducing noise levels around patient care areas of the hospital.
Stair Climbing Cane

Project Overview
Ascending and descending stairs present a significant stability problem to disabled people. Our team decided to design a cane to help with this problem. Our stair-climbing cane adds two prongs to the normal cane structure so that the cane can be in contact with two steps simultaneously, increasing stability and therefore safety for the user. We performed prototype validation by compressively loading the cane. To demonstrate increased stability, we had human subjects compare the stair-climbing cane and a normal cane on stairs and collected kinematic data from both.
