摘要： A method for ablating target tissue includes the steps of: (a) delivering an ablation balloon catheter to the target tissue, wherein the ablation balloon catheter includes a compliant balloon, a visualization device; and an electrode array that is visible to the visualization device, each electrode being configured to deliver ablation energy, wherein the electrode array is independently movable relative to the compliant balloon; (b) isolating the target tissue such that at least one electrode of the electrode array is in contact with the target tissue; and (c) delivering the ablation energy to those electrodes of the electrode array that are confirmed, using the visualization device, to be in contact with target tissue.

摘要： Systems and methods for controlling fill media in a balloon catheter are disclosed. The system comprises a catheter having an inflatable balloon, a reservoir for fill media, and a first conduit for delivering fill media from the reservoir to the balloon. The system includes a second conduit for returning fill media from the balloon to the reservoir and a pump configured to circulate fill media through the conduits. The system also includes a valve assembly configured for placement in at least three positions. In the first position, fill media is delivered from the reservoir to the balloon to inflate the balloon. In the second position, fill media is drawn out of the balloon and returned to the reservoir. In the third position, fill media circulates through the conduits between the pump and the balloon and is prevented from flowing back to the reservoir.
