Embodiment Construction

[0034] Methods, systems and devices for treating gastrointestinal disorders with ablative energy are described. A number of different ablation modalities are described and examples of devices and methods for applying different types of ablation energy are provided. The examples described relate to the treatment of ulcerative colitis, but the techniques described can also be used to treat ulcerative proctitis, colitis, irritable bowel syndrome, Crohn's disease, dysplastic lesions, or any other condition of the gastrointestinal tract Inflammatory conditions.

[0035] Techniques for treating ulcerative colitis may include delivering energy to affected tissue and ablating the tissue to a controlled depth. Ablation to a controlled depth may include ablation of the biofilm layer covering the tissue surface, ablation of one or more specific layers of affected tissue, ablation within the crypts of the tissue mucosal layer, and / or ablation of nerves in and below the tissue mucosal layer...

Abstract

Methods, systems, and devices are described for treating diseases of the gastrointestinal tract, including ulcerative colitis, by delivering ablative energy to a tissue surface of the gastrointestinaltract and ablating the tissue to a controlled depth. Ablating the tissue may include removing a biofilm layer or coagulating tissue.

Description

technical field [0001] Features described herein generally relate to methods, systems, and devices for treating gastrointestinal disorders with ablative energy. The techniques described herein can be applied to treat ulcerative colitis, ulcerative proctitis, colitis, irritable bowel syndrome, Crohn's disease, or dysplastic lesions. In particular, the present invention relates to a device for treating ulcerative colitis in a patient. Background technique [0002] Inflammatory bowel disease (IBD) generally refers to chronic inflammatory conditions in the human digestive tract and encompasses a variety of specific conditions, including ulcerative colitis and Crohn's disease. Ulcerative colitis is characterized by recurrent ulcers affecting the colon and rectum, which can cause diarrhea, bleeding, and abdominal pain of varying degrees. [0003] The etiology of ulcerative colitis is unknown, and a number of alternative theories have been proposed, including genetic predispositi...
