Abstract
Methods, apparatuses and systems are described for preventing the over-tightening of a furled ablation structure support around an expandable member. An ablation device for treatment of tissue in body lumens with varying sizes is disclosed. The ablation device may include a catheter, an expansion member coupled with a distal portion of the catheter, and an ablation structure support configured to at least partially unfurl or furl around the expansion member as the expansion member expands or contracts. The ablation device may further include a spacer coupled with the catheter and configured to limit a minimum diameter of the ablation structure support when the expansion member is completely contracted.
