Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter shaft. An expandable balloon may be coupled to the catheter shaft. The balloon may be capable of shifting between a folded configuration and an expanded configuration. A plurality of elongate electrode assemblies may be disposed on the balloon. A cover layer may be deposited on the electrode assemblies. Portions of the electrode assemblies may be free of the cover layer.

Ablation balloon with vapor deposited cover layer

A catheter assembly configured for treatment of a vessel bifurcation. The catheter assembly includes a catheter shaft and first and second balloons. The second balloon extends radially outward relative to the first balloon when expanded. A valve arrangement controls expansion of the second balloon. Portions of the valve arrangement can be positioned at proximal and distal end portions of the catheter shaft. Typically, the first balloon is expanded followed by expansion of the second balloon. A stent having a lateral branch opening is operatively mounted to the first balloon. The second balloon is configured to extend through the lateral branch opening when the second balloon is expanded.
