Zusammenfassung:SELF-SIZING CATHETER FEATURES TO PREVENT OVER TIGHTENING OF THE ELECTRODE An ablation device (100) for treatment of tissue in body lumens with varying sizes comprising: a catheter (115); an expansion member (120) coupled with a distal portion (140) of the catheter (115); an ablation structure support (180) configured to at least partially unfurl or furl around the expansion member (120) as the expansion member (120) expands or contracts; and a spacer (185a) coupled with the catheter (115) and configured to limit a minimum diameter of the ablation structure support (180) when the expansion member (120) is completely contracted.
