We build mechanical, tip-transforming catheters on a metamaterial platform — technology that adapts to the body, instead of asking the body to adapt to it.
Anatomy is endlessly varied. The tools that navigate it are not. When a fixed shape meets a body it does not match, the search begins: one catheter after another, while the clock runs.
PROTEUS™, our metamaterial platform, builds the motion into the structure itself — so one device can deflect, extend, and expand on command.
Bend precisely, exactly where it’s needed.
Reach further, without losing control.
Open into a sphere, then settle back to neutral.
Because the behavior lives in the design, the same platform scales across the body — from the smallest coronary vessels to the structures of the heart, the periphery, and the brain.
A guide catheter with a tip that transforms — threading the same path as any catheter, until its distal cage expands to anchor exactly where it matters.
Percutaneous coronary intervention (PCI): threading a catheter to the heart to clear a blockage and place a stent.
In up to 30% of cases, rigid catheters lose their backup — prolapsing and slipping just when force is needed for delivery.
Longer procedures, repeat attempts, added complications, avoidable cost.
FlexLock’s cage expands to anchor against the vessel wall — stable backup, on demand.
Fewer detours. Less guesswork. More patients reachable with procedures that already work. A field worth tens of billions is still waiting on tools to match its ambition — that is the gap we close.
Nimble Surgical is a team of scientists, engineers, and clinicians working at the edge of mechanical engineering and interventional medicine — building the catheter the next generation of procedures deserves.
