Abstract
Apparatus for the treatment of Barrett's esophagus, including: an inflatable balloon for insertion into the esophagus, an endoscope for passing inside the balloon on a distal end thereof, a laser fiber apparatus for insertion within the balloon in the esophagus, and a balloon inflation/deflation means in fluid communication with the balloon for inflating and emptying the balloon into and out of contact with the walls of the esophagus to be treated. The balloon may occlude the stomach from the esophagus during treatment.
Claims11
A method of treating an esophageal lesion by inserting an inflatable balloon within the esophagus, said esophagus having a wall portion, the method including:
- placing a laser fiber and a visualization port in said balloon;
- inflating said balloon;
- steering said laser fiber and said visualization port individually within said balloon to a lesion, so as to enable treatment of the lesion within the esophagus;
- and
- transmitting laser energy through said fiber within said balloon to effect laser radiation treatment of a lesion on said wall of the esophagus adjacent said balloon, wherein said laser generates a laser light wavelength of about 520–650 nm and a pulse width of about 0.2–100 ms.
A method of treating an esophageal lesion by inserting an inflatable balloon within the esophagus, said esophagus having a wall portion, the method including:
- placing an visualization port and a laser fiber in said balloon;
- inflating said balloon;
- bendably steering both said port and said fiber independently of one another in said balloon;
- and
- transmitting laser energy through said fiber within said balloon to effect laser radiation treatment of a lesion on said wall of the esophagus adjacent said balloon, wherein said laser generates a laser light wavelength of about 520–650 nm, wherein said optical fiber is less than 600 microns in diameter.
