Boston Scientific

I completed my first co-op at Boston Scientific Headquarters in Marlborough, MA from July - December 2022 as a Mechanical Engineering intern.

Material Testing

Using the Instron, I executed three-point bend, axial compression, and kink testing on several endoscope shaft materials. This testing was done to compare their material properties and make informed design decisions.


Imaging Software

At the beginning of my co-op, I conducted several experiments and concluded that there is no statistically significant difference in measurements made by the Keyence and Dino-Lite measuring instruments. This allowed the other engineers and I to use the more portable Dino-Lite device for image capture and analysis going forward.

Statistical Analysis

During the second-part of my co-op, I investigated the articulation of SpyGlass™ DS Devices. After following written test methods to record data in Excel using the Keyence machine, I utilized Minitab to conduct a Gage R&R test to determine if the articulation of the devices is both repeatable and reproducible.


Technical Reports

During my time at Boston Scientific, I wrote two technical engineering reports. Feedback about Boston Scientific products was gathered at Digestive Disease Week (DDW) and the Society of Interventional Radiology (SIR) conventions from physicians via a questionnaire. I quantified and analyzed this qualitative consumer feedback to generate two formal written reports.

MATLAB Analysis

A laser machine was used to obtain data describing the outer diameter and the ovality of relieved and non-relieved endoscope shaft samples. Each sample contained two distinct sections of different density with a transition region in between. I wrote a MATLAB script to determine where the transition region began in each shaft. With this information, the script analyzed each region separately for accurate results.


CAD Fixture Parts

Towards the end of my co-op, I was tasked with designing 3D printed pieces to hold the tip of EXALT™ Model D in place for a test fixture. I designed two pieces in SolidWorks that fit together in two configurations, allowing the tip of the duodenoscope to be positioned for two distinct endoscope deflection angles.


Distal Cap FEA

At the very end of my co-op, I designed my own test method to obtain data regarding the mechanical performance of distal caps of two different plastics. I tested samples of each material in the Instron and used Minitab to prove that there is no statistically significant difference in the strength of the two materials for the current iteration of the cap design. Further, I conducted several studies for each material using SolidWorks FEA to analyze the deformation of each cap.
