Pre-formed cardiac catheter for performing a coronary angiography

摘要

The preformed cardiac catheter has a continuous hollow lumen (1) for injecting a radiographic contrast liquid in coronary arteries, which has straight and stiff shaft section. The hollow lumen is configured for direct sequent application in the right coronary artery and the left coronary artery, in which these arteries have a resilient proximal curvature (4).
