ViewFlow hemodynamic visualization

See what surgery
has been missing

Glow dye company's market. ViewFlow's playbook.

Live flow imaging today. Built AI-ready.

Blood flow is still invisible during surgery.

Today's tools confirm that blood is flowing — not how it flows.

The number one problem surgeons face is knowing if the procedure ends with adequate blood flow.
— Dr. Patel, 20,000 robotic surgeries performed

And the data proves him right

Heart bypass grafts have insufficient flow — discovered only after complications arise.

And Across Diverse Therapies
The same blind spot extends across:
CABG & saphenous bypass · colorectal anastomosis · esophageal repair · bile-duct surgery · microvascular flap & limb-salvage — and more.

What no surgeon has ever seen before during surgery — until now

A smart camera.
No contact. No dye.
Instant clarity.

  • Contact-free — no disruption to surgical workflow
  • Enabling Real-Time Insights into Hemodynamic Blood Flow
  • On demand — point the camera and flow appears in real time
  • Simultaneously see fast, stagnant, and recirculating flow

“Who would want to visualize flow through graft and coronary for obstructive disease — on the table — after cross-clamp — before coming off pump?”

An easier, faster camera
for a proven playbook

ViewFlow targets the same surgeons, same workflow, and same operating rooms as the glow dye (fluorescent) imaging — but without requiring dye injection.

5 million of 500 million surgeries use a functionally objective tool to assess adequacy of blood flow.

Built by scientists.
Validated by surgeons.

A rare intersection of laser physics, life science experience, and building novel visualization — guided by advisors from the nation's top surgical institutions.

Duke PhD, MBA

Jim turns new insights into new technologies. Published in quantum dynamics as an undergraduate. Led cybersecurity and systems engineering at a Lockheed Martin national computing center. Developed an AI-ready cheminformatics platform, licensed by Merck and Roche. And now, an AI-ready surgical camera.

ViewFlow is the culmination: FDA-listed, it shows surgeons how blood flows in real time — no dyes, no contact, no radiation. The last company in this space sold to Stryker for $701M.

He has long helped others build, too: as adjunct faculty in the Duke and NC State MBA and MEM programs, including while starting ViewFlow, and as ViewFlow's sponsor, he led 30 practicums for Fortune 1000 companies and startups, and he assessed over 100 inventions for NASA and university tech transfer offices.
