Elastic Band Ligation (Boston Scientific)
Endoscopic Band Ligation is a hemostasis technique used for esophageal varices, which are protruding vessels caused by hypertension in the portal venous system. The band ligator is an attachment to the distal end of an endoscope that deploys elastomeric bands over varices, cutting off blood flow, and eventually causing the varices to fall off. The current treatment device involves a tedious, laborious assembly by the factory workers. There are additional product development opportunities in usability and alternative methods of band deployment. Therefore, the Olin College SCOPE team is working with Boston Scientific to investigate designs for alternate methods of ligation band deployment that address these issues. The project will involve mechanical design, component testing, materials selection and analysis, and manufacturing analysis. The team will brainstorm concepts and develop rough prototype devices. They will then use modeling, prototyping and testing methods to assess the effectiveness of the final design. The main goal of the project is to provide Boston Scientific with a prototyped design that increases the product's manufacturability and meets the needs of their customers.
