AI Technical Summary
Existing technologies, when simulating the entry of microcatheters into aneurysms, cannot simultaneously meet the physical laws of morphological formation and the needs of physicians, especially in scenarios where blood vessels are tortuous and require secondary bending, the microcatheter tip is difficult to shape for entry into the aneurysm or provides poor support.
By acquiring vascular reconstruction models and anatomical parameters, calculating key feature points, adjusting benchmark control points in conjunction with aneurysm incidence angles, performing spline fitting and wall-touching calibration, generating microcatheter shaping results including primary and secondary curvature, and simulating the pushing operation using an elasticity model.
It enables the microcatheter to be easily inserted into the aneurysm and provides stable support, adapts to the doctor's operating habits, and meets the operational needs of proximal tamponade, step-by-step catheter removal, and distal tamponade.
