| 摘要 |
A catheter has a distal section that includes a spring member having at least a slot, a rib and a spine for biasing the distal section for deflection within a single plane. Depending on the plurality and orientation of slot(s), rib(s) and spine(s)s, the distal section can allow for deflection in two opposing directions while allowing only limited deflection in perpendicular directions to maintain torquability, axial loading capabilities, and side force performance.
