Endovascular surgical robotics helps physicians perform minimally invasive procedures inside blood vessels. It provides motorized, software-assisted control of catheters, guidewires, and related delivery tools.
Endovascular means working inside the vessel channel, usually entered through a small puncture in the groin or wrist. The robot does not act on its own. A trained operator guides every motion using live X-ray imaging.

Which procedures use it?
Endovascular robots focus on catheter-based treatment of narrowed, blocked, or weakened vessels. Typical targets include coronary arteries, leg arteries, and selected vessels leading to or inside the brain. Use varies by center, anatomy, and compatible tools.
The shared task is navigation followed by delivery. The operator steers a guidewire, a thin steering wire, and a catheter, a slender tube, to the target. The system then helps position balloons, stents, coils, or clot-removal tools. The physician still chooses devices and makes treatment decisions.
How does control work during a case?
A common design pairs a bedside drive with a remote workstation. The drive grips and advances the wire and catheter in small, controlled increments.
The operator sits nearby, watches fluoroscopy, a continuous X-ray video, and commands motion with joysticks, buttons, or touch controls. A case usually follows this pattern: Automation assists motion, imaging alignment, and stable holding. It does not plan treatment or replace bedside judgment.
- the physician gains vessel access by hand and connects selected tools to the drive
- the operator moves to the workstation and navigates the wire and catheter under imaging
- the operator delivers balloons, stents, or other implants through the positioned catheter
- staff exchange devices at the bedside when the procedure requires a different tool
Why use a robot for catheter work?
Catheter work rewards small, steady movements. A robotic drive can advance, retract, and rotate in fine increments and hold position without hand tremor. That steadiness helps during long navigation, precise stent placement, and repeated manipulations.
The workstation also changes working posture and position. The operator can sit and work farther from the X-ray source, which can reduce routine occupational radiation exposure and physical strain. Teams often value repeatable motion, clearer division of roles, and less fatigue during extended cases.
What limits practical use?
Robotic control does not remove the hard parts of vascular access and anatomy. Initial puncture, sheath placement, and bailout actions remain manual. Sharp bends, severe calcification, and unstable lesions can still require manual technique or open conversion. Compatibility and workflow matter as much as motion.
Not every wire, catheter, balloon, or stent size fits every drive. Setup takes room, training, and coordination between the bedside team and the console operator. Touch feedback is reduced, so operators rely more on imaging cues and learned resistance. Before adoption, a lab usually checks compatible device sizes, room layout, and hands-on training time.
