Overview

Overview

Forme catheter is a novel arterial catheter that can change shape in real-time in response to a patient’s unique vasculature. It contains embedded springs at three different locations that compress to form a variety of different shapes within a single catheter.

As part of a semester-long senior undergraduate capstone course in Biomedical Engineering, I worked with three classmates to design a catheter to resolve issues that occur during interventional radiology procedures. We were mentored by three Interventional Radiologists (IRs) from Emory University Hospital Midtown in Atlanta, GA. I acted as both project manager and design lead, generating a medium fidelity physical prototype. My team and I won Best Overall Project out of over 200 teams from various engineering disciplines at the Spring 2018 Georgia Tech Capstone Design Expo.

Project Goals

Adapt to each patient

Adapt to each patient's unique vasculature and how it changes in real-time.

Reduce waste

Reduce the number of catheters required per procedure from 3-10 to one.

User Goals

Decrease procedure time

$2,550 is spent per procedure on OR costs while positioning the catheter.

Access more vasculature

Increase procedure efficiency, reduces need for radiation, and decreases patient pain.
