Meet Endolumik

The idea behind Endolumik came to Dr. Nova Szoka as she performed hundreds of bariatric surgeries at West Virginia University hospital, and was looking for a way to increase bariatric success rates, while making her own procedures more efficient.

What Dr. Szoka created with co-founder and CEO Mara McFadden is Endolumik, a surgical device company founded in Morgantown, West Virginia. Together, they have developed a patented fluorescence-guided gastric calibration system (i.e. bougie) for use in gastrointestinal surgery.

Endolumik has grown to envision a new generation of surgical tools that use light and digital surgery techniques to enhance surgeon performance.
