Abstract
Devices and methods can be used to treat long gap esophageal atresia, while obviating much of the delay and complexities associated with current procedures. The devices and methods involve actively stretching the esophagus portions with traction to promote growth of the esophagus portions. Moreover, the devices and methods provided allow for a compression anastomosis to occur between the esophageal ends. This eliminates the need for a second operation to suture the esophageal ends together.
Claims15
A method of treating esophageal atresia by esophageal lengthening and creating an esophageal anastomosis, the method comprising:
- advancing a sheath defining a lumen in which a balloon catheter is slidably disposed into a first esophageal segment that extends from a mouth of a patient so that a distal end portion of the sheath abuts a terminal end of the first esophageal segment;
- passing a distal end portion of the balloon catheter through the terminal end of the first esophageal segment;
- passing the distal end portion of the balloon catheter through a terminal end of a second esophageal segment that extends from a stomach of the patient, wherein the distal end portion of the balloon catheter includes a balloon member;
- inflating the balloon member while the balloon member is residing in the second esophageal segment;
- and
- exerting a first tension on the balloon catheter in relation to the sheath so that the terminal end of the first esophageal segment and the terminal end of the second esophageal segment are drawn closer to each other.
