Abstract
An electrode (), an electrophysiology catheter () and an ablation system are disclosed. The electrode () is configured to be disposed at a distal end of a catheter () and includes a proximal electrode portion (), a main electrode portion () and a distal electrode portion (), which are sequentially joined together from a proximal end to a distal end of the electrode. The main electrode portion () includes a first section () and a second section (), which are joined to each other along an axis of the catheter (). At least one of the proximal electrode portion () and the distal electrode portion () is configured to be movably connected to the catheter (). The main electrode portion () is configured to switch between a contracted configuration and a folded configuration along with relative movement of the proximal electrode portion () and the distal electrode portion () along the catheter (). When the main electrode portion () is in the contracted configuration, the main electrode portion () expands outwards in the radial direction of the catheter (), such that the first section () and the second section () are inclined relative to each other and staggered in the transverse direction of the catheter (). Configuring the main electrode portion () in this way in the folded configuration, instead of twisting the electrode () to stagger the sections, can avoid a reduced contact area, or even increase the contact area, between the main electrode portion () and a predetermined site. This can improve an electric field present around the predetermined site and enhance ablation performance.
