摘要

球囊扩张导管在颅内动脉狭窄治疗中的应用逐渐增多。然而，关于不同类型球囊的可行性和有效性的研究仍然相对较少。本研究设计了三种不同材料的导管模型，以模拟球囊卷曲、分裂和扩张过程。顺应性球囊会产生较大的变形，扩张不良，并出现应力集中现象。在扩张过程中，半顺应性球囊在内膜和病变区域产生的剪应力小于非顺应性球囊。这些结果证明了使用半兼容球囊的可行性。

Simulation analysis of different types of balloon dilatation catheters for the treatment of intracranial arterial stenosis.

The application of balloon dilation catheters in the management of intracranial arterial stenosis has been gradually increasing. However, studies on the feasibility and effectiveness of different types of balloons remain relatively scarce. In this study, catheter models of three different materials were designed to simulate balloon crimping,splitting, and dilatation processes. A compliant balloon produces large deformations with poor dilatation and a stress concentration phenomenon. During dilatation, the shear stress generated in the intima and lesion area by the semi-compliant balloon was smaller than that generated by the non-compliant balloon. These results demonstrate the feasibility of using semi-compatible balloons.

期刊介绍： The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
