AI Technical Summary

Technical Problem

In complex vascular environments, existing technologies lack precise stent deployment simulation tools, making it difficult for stents to achieve the expected shape and coverage within the blood vessel, thus affecting the safety and effectiveness of interventional treatment.

Method used

By establishing a simplified compression model, the deployment process of vascular stents is simulated using node particles and ghost particles. Combined with geometric constraints and physical elastic constraints, the deployment state of the stent in the target vascular segment is accurately simulated.

Benefits of technology

It improves the computational efficiency and accuracy of stent deployment simulation, ensuring that the simulation results are consistent with the actual deployment state, and provides a scientific basis for preoperative surgical planning.

Abstract

This application discloses a method, electronic device, and computer-readable storage medium for simulating vascular stent deployment. The method includes: establishing a simplified compression model of the vascular stent in the microcatheter based on the microcatheter size, wherein the vascular stent includes multiple interwoven braided filaments in a helical structure, and the simplified compression model includes node particles on the simplified helical lines of the braided filaments and ghost particles on the central axis segment of the vascular stent; obtaining a vascular model including a target vascular segment, the vascular model including a vascular centerline and a vascular wall; arranging the simplified compression model along the vascular centerline, wherein the ghost particles are located on the vascular centerline, and the node particles form a helical structure around the vascular centerline; and simulating the deployment process of the vascular stent in the target vascular segment by applying geometric and physical elastic constraints to the vascular stent to obtain a vascular stent deployment model. According to the method of this application embodiment, a reliable stent deployment morphology can be obtained.
