摘要：
A flexible tip electrode for an ablation catheter and methods for making the same are disclosed. The electrode has a surface configuration that improves flexibility of the electrode. Also, the surface configuration may allow electrode lengthwise freedom of movement, such that the electrode may be shortened when pressed against the target tissue. A coil may be located in the electrode to bias the electrode toward a predetermined configuration.
