The comparason investigation of different materials and characters of interventional guiding catheter / 中国医学装备

ABSTRACT

Objective: This paper focuses on the most commonly used Guiding Catheter and conduct study on material selection, push force, torque and twist controllability. Methods:In contrast to the method used in our clinical surgery three foreign manufacturers of medical guidelines for catheter materials, testing foreign manufacturers’ products. Conclusions analyzing t foreign products their own characteristics, provide the technical basis for better medical research and clinical guidelines for catheter performance. Results: Three foreign guiding catheter manufacturers selected the same materials, after testing, the guiding catheter has the best maximum pushing force, can quickly reach the site of disease. Conclusion: The guiding catheter has the best torque control, can better use in distorted vessel;the guiding catheter has the best twist controllability, can deal with complex vascular anatomy.
