What Endolumik does
Endolumik is a privately held medical device company headquartered in Morgantown, West Virginia, that develops fluorescence-guided surgical tools for minimally invasive bariatric and gastrointestinal procedures. The company's core product, the Endolumik Gastric Calibration Tube, is a single-use disposable bougie that emits near-infrared (NIR) light from inside the stomach, enabling surgeons to visualize the calibration tube in real time through thick stomach and adipose tissue using any NIR-capable laparoscopic or surgical robotic camera. The device integrates NIR illumination, suction regulation, measurement markings, leak-test capability, and wireless battery power, eliminating the need for injectable contrast agents (ICG). Endolumik received FDA 510(k) clearance in March 2023 as the first device ever authorized under the FDA's Safer Technology Program (STeP), and began commercial sales in June 2023.
The company sells directly to US hospitals and surgery centers through a purchase-order-based enterprise field sales motion, with product SKUs in two sizes (36Fr and 40Fr) and two variants (standard and M Series) packaged in boxes of five units. Pricing is not publicly disclosed. Endolumik's go-to-market relies on surgeon champions and KOL advocacy, peer-reviewed publications, and active participation in bariatric and surgical conferences (SAGES, ASMBS, IFSO, and state societies). Strategic financial backing includes the SAGES Ingenuity Fund and Varia Ventures through the SINC Opportunity Fund, alongside earlier investment from Innovation Works and Country Roads Angel Network. The company is women-owned and women-led, co-founded by bariatric surgeon Dr. Nova Szoka (Chief Medical Officer) and Mara McFadden (CEO), and holds a granted US patent (#11,389,266) with a pending continuation application covering the fluorescence-guided calibration system.

Endolumik product offering
Product offeringCore offering
Endolumik develops and sells the Endolumik Gastric Calibration Tube, a single-use, fluorescence-guided esophagogastric calibration bougie used in minimally invasive bariatric and gastrointestinal surgery. The device emits near-infrared (NIR) light from within the stomach to allow surgeons to visualize the calibration tube through tissue during sleeve gastrectomy and gastric bypass procedures, and is sold directly to hospitals and surgery centers in the US.
Product overview
Endolumik offers a single product line: the Endolumik Gastric Calibration Tube system, a fluorescence-guided surgical device for bariatric procedures. The system consists of the core Endolumik Gastric Calibration Tube available in two sizes (36 French and 40 French) and two variants (standard and M Series). The device integrates near-infrared (NIR) lighting technology to enable real-time visualization through stomach tissue during laparoscopic and robotic surgeries, helping surgeons perform more accurate sleeve gastrectomy and gastric bypass procedures. The product is single-use, wireless, and requires no injection of contrast agents.

Endolumik competitors and assessment
Company assessmentBroad incumbents
- Ethicon (Johnson & Johnson MedTech): Ethicon is a dominant surgical devices and stapler franchise, including products used in bariatric sleeve and bypass procedures. It is a broad incumbent in the same surgical procedure category where Endolumik competes for hospital budget and OR shelf space.
- Medtronic: A major manufacturer of bougies and a broad portfolio of bariatric and general surgery devices. Medtronic is a relevant incumbent competitor in the same end market (bariatric surgical instruments) even though it does not offer a direct fluorescence-guided equivalent.
- Karl Storz: A leading endoscopy and laparoscopy systems manufacturer whose NIR-capable camera platforms Endolumik explicitly integrates with. Karl Storz is both a key enabler of Endolumik's installed-base reach and a broader incumbent in minimally invasive surgical visualization.
- Olympus: Major endoscopy and surgical visualization platform provider with NIR/IR fluorescence imaging capabilities in modern laparoscopic towers. Olympus's installed OR base is one of the distribution channels Endolumik relies on for adoption.
- B. Braun: A large surgical instruments and devices manufacturer, including bougies and other gastrointestinal surgery tools. B. Braun competes in the same accounts (hospital ORs) with commodity and premium surgical consumables that overlap with Endolumik's end users.
Direct peers
- Intuitive Surgical: Makes the da Vinci surgical robot with integrated Firefly NIR/ICG fluorescence imaging. Endolumik's device is explicitly designed to work with da Vinci's NIR visualization, making Intuitive both a key platform dependency and a potential competitor if they bundle their own fluorescence-guided accessories.
- Stryker: Owns the SPY fluorescence imaging platform (via the Novadaq acquisition) and manufactures traditional bougies and surgical instruments used in bariatric surgery. Stryker directly competes on fluorescence-guided visualization and adjacent surgical disposables.
- Fluoptics: A specialty company focused on fluorescence-guided surgery imaging systems. Like Endolumik, Fluoptics operates in the fluorescence-guided visualization niche for open and minimally invasive surgery and represents the closest pure-play comparable in the space.
- Curadel: Develops fluorescence imaging devices for surgical and research use, including NIR-labeled probes and visualization tools. Curadel is a small, niche peer competing in the same fluorescence-guided surgery category as Endolumik.
Emerging players
- Apollo Endosurgery: Specializes in endoscopic bariatric and gastrointestinal devices (including endoscopic suturing and gastric balloon products). Apollo overlaps with Endolumik in the endoscopic bariatric procedure market, though via different device categories.
