The Endolumik System

Illuminating the Potential of Laparoscopic Surgical Devices

The Endolumik surgical device lights the stomach from within using Near-Infrared (NIR) light.  This light allows the surgeon to see the calibration tube clearly through thick layers of stomach or adipose tissue. Unlit or white light bougie devices are not consistently visible through thick gastric tissue or when the stomach is covered with fat. The Endolumik device emits the same wavelength as ICG, and is visible with any NIR-capable camera.  The integrated suction enables teams to minimize tool swaps. With improved visualization and functionality, our goal is to help surgeons decrease complications, improve OR workflow, and create a more standardized gastric sleeve and gastric pouch.

So what Exactly is Fluorescence-guided surgery?

Fluorescence-guided surgery (FGS) is a medical imaging technique that uses fluorescent dye or a near-infrared emitting light source to identify anatomy or structures during surgical procedures. FGS is a rapidly growing field that provides visual cues to improve surgical precision and improve surgical decision making.

Endolumik leverages Existing infrastructure

Near Infrared (NIR) is the lighting technology used in leading laparoscopy towers and surgical robotic systems. The Endolumik system integrates with any camera capable of capturing NIR spectrum light, and all Laparoscopic  and surgical robotic equipment that possess NIR imaging capabilities will work with our device.

Our Features

The endolumik System is designed to optimize workflow for surgical teams

Precision Visibility

See the exact location and position of your bougie at all times during the operation.

Injection-Free Fluorescence

The system is Iodine free and does not require any mixing and injecting ICG.

Zero Set Up

Works with any NIR imaging system and there’s no set up required.


Internal batteries power the infrared capabilities so there are no power cords.

Single Use

Our system is disposable which eliminates the need for cleaning between patients.

Accurate Measurements

The featured 5 mm hatch marks enable increased precision from within.

The Problem We Solve

Bariatric Surgical Teams are Currently operating Blind

Currently, the bougie devices being used for bariatric surgery are not well seen. In 2019 alone, there were 256,000 bariatric surgeries performed in the United States and during all of these bariatric operations, the bougie calibration device wasn’t easily visible.  Poor visualization of bariatric calibration tubes has led to significant surgical complications including: perforation of the stomach or esophagus, excessive narrowing of the gastric sleeve resulting in gastric sleeve leak, as well as the calibration tube being stapled across inadvertently.

Lack of tool visibility can cause
life-changing complications.

Robotic operations lack tactile feedback.

The Endolumik device can improve visual feedback during surgery.
