摘要
Disclosed are various embodiments of systems, devices, components and methods for re-positioning or displacing a patient's esophagus a safe distance away from the patient's heart during an atrial ablation surgical procedure. An esophageal displacement catheter is disclosed that is configured to reposition a patient's esophagus 20 mm or more away from the ablation location in the patient's heart. A distendable section of the catheter is configured such that portions of a first pulling member extend sufficiently far away from joints located in the distendable section when the first pulling member is in a retracted position to permit the distendable section to assume a deployed and distended configuration. At least one flexible deformable or distendable member, sheath or covering is configured to be disposed over and cover the portions of the first pulling member extending away from the joints when the distendable section is the deployed and distended configuration. One or more balloons can also be incorporated into the catheter to enlarge controllably the diameter of the distendable section.
