摘要： A catheter system includes a head including ports, a tail including conduits, and a medical balloon located between the head and the tail. Each conduit is connected to one of the ports. The medical balloon comprises ridges located around a circumference of the medical balloon. One or more sensors are located in the conduits. The catheter system can be used for ablation of the left atrial appendage using an ablation agent. The catheter system is capable of sealing the left atrial appendage, administering the ablation agent, delivering rinsing fluid into the sealed cavity, and extracting liquid from the sealed cavity.

摘要： Catheter ablation systems are used to isolate the Left Atrial Appendage (“LAA”), or portions of the LAA, by using balloons. The systems deliver an ablation fluid such as alcohol in order to destroy the LAA tissue isolated between the balloons, deliver saline to dilute the ablation fluid, and remove excess fluid and particulates by suction to prevent excess residual alcohol from remaining in the LAA.
