Autonomous traversal of the Circle of Willis using magnetically steered micro-catheters to deliver embolization coils.
Navier-Stokes solvers running on GPUs compute time-varying shear stress in patient-specific vascular anatomies, timing magnetic pulses to advance during diastolic phases when flow velocity is minimal.
By deflecting guidewire tips magnetically within milliseconds, the system accesses 90-degree acute branch vessels that typically resist manual catheterization.
In silicon vascular models replicating human cerebral aneurysms, magnetic navigation reduced catheter placement times from an average of 24 minutes to under 4 minutes.
