AI Technical Summary

Benefits of technology

This solution simplifies the treatment procedure, enhances direct visualization, and ensures more accurate ablation of diseased tissue while minimizing patient discomfort by integrating suction and energy delivery within a single system.

Problems solved by technology

Without adequate treatment, GERD can cause erosion of the esophageal lining as the lower esophageal sphincter (LES), a segment of smooth muscle located at the junction of the stomach and the esophagus, gradually loses its ability to function as the barrier that prevents stomach acid reflux.
The balloon inflated treatment device and procedure requires an additional step to size the balloon and adds more time and potential patient discomfort to the treatment procedure.
In addition, the inflated balloon is positioned in front of the endoscope viewing window, preventing direct visualization of the target tissue and potentially leading to ablation of healthy tissue or incomplete ablation of diseased tissue.

Embodiment Construction

[0020]The invention is described with reference to the drawings in which like elements are referred to by like numerals. The relationship and functioning of the various elements of this invention are better understood by the following detailed description. However, the embodiments of this invention are not limited to the embodiments illustrated in the drawings. It should be understood that the drawings are not to scale, and in certain instances details have been omitted which are not necessary for an understanding of the present invention, such as conventional fabrication and assembly.

[0021]As used in the specification, the terms proximal and distal should be understood as being in the terms of a physician delivering the stent to a patient. Hence the term “distal” means the portion of the ablation overtube that is farthest from the physician and the term “proximal” means the portion of the ablation overtube that is nearest to the physician.

[0022]FIG. 1 illustrates an embodiment of a...

Abstract

An energy delivery system and a method of delivering energy to a tissue are provided. The energy delivery system includes an overtube. The overtube includes a body having a proximal portion, a distal portion and a lumen extending at least partially therethrough. The proximal portion is adapted to be positioned over a distal portion of an endoscope. The body also includes a first plurality of openings formed in the body and connected to the lumen and an electrode operably connected to the body and extending over at least a portion of a surface of the body. The lumen is operably connectable to a vacuum source and the electrode is operably connectable to a power source.

Description

RELATED APPLICATIONS[0001]This application is a divisional application of U.S. application Ser. No. 13 / 209,763, filed Aug. 15, 2011 which claims the benefit of U.S. Provisional Application No. 61 / 378,732, filed Aug. 31, 2010, which are incorporated by reference herein in their entirety.BACKGROUND[0002]Millions of people suffer from progressive gastroesophageal reflux disease (GERD) which is characterized by frequent episodes of heartburn, typically on at least a daily basis. Without adequate treatment, GERD can cause erosion of the esophageal lining as the lower esophageal sphincter (LES), a segment of smooth muscle located at the junction of the stomach and the esophagus, gradually loses its ability to function as the barrier that prevents stomach acid reflux. Chronic GERD can also cause metaplasia to the inner lining of the esophagus where the normal squamous mucosa changes to columnar mucosa, also known as Barrett's esophagus. Barrett's esophagus can progress to esophageal cancer...
