摘要： Disclosed herein are intestine pleating attachable structures for use with endoscopes and methods for using said structures. The intestine pleating attachable structures may act in conjunction with a gastrointestinal endoscope and, optionally, a balloon to improve visualization during endoscopic procedures. The intestine pleating attachable structures are coupled to the endoscope shaft, and include at least one flexible appendage to enhance contact between the structure and the intestinal wall. When the endoscope is retracted, the flexible appendage assists in moving the intestinal wall relative to the imaging system. This movement causes the intestine to pleat. Pleating reduces looping, improves efficiency, and results in a less painful endoscopic procedure for the patient. The attachable structures may be used in conjunction with a dome-shaped balloon that is inflated at the distal, imaging end of the endoscope. The balloon is transparent, such that the intestinal wall may still be visualized through the balloon while intestinal matter is prevented from obscuring the image.

摘要： Disclosed herein are intestine pleating methods and devices for use with gastrointestinal endoscopes. Devices include balloon access device, attachable structure(s), and an elongate overtube. Attachable structures may be used to pleat intestinal wall and to advance the endoscope past difficult to navigate areas. Balloon access device may be used to improve visualization of intestinal wall and to pleat intestinal wall. These systems may be used during airless endoscopic procedures that do not require insufflation of the intestinal cavity. The systems may be used during airless intubation procedures. To pleat the intestine, the practitioner inflates balloon to a fully or nearly fully inflated state when a difficult area is encountered. Inflation of the balloon to fully or nearly fully inflated state ensures contact with intestinal wall. Practitioner pulls back on the endoscope shaft to drag intestinal wall back toward the proximal opening of intestinal cavity. Pleating facilitates forward advancement of endoscope.

摘要翻译： 本文公开了肠胃打褶方法和用于胃肠内窥镜的装置。 装置包括气球进入装置，可附装结构和细长的外套管。 可以使用可附接结构来折叠肠壁并使内窥镜前进困难导航区域。 气囊进入装置可用于改善肠壁和褶皱肠壁的可视化。 这些系统可以在不需要肠腔注射的无气内窥镜手术中使用。 该系统可以在无气管插管过程中使用。 为了打褶肠道，当遇到困难的地方时，医生将气球充气至充分或几乎完全膨胀的状态。 气囊充气或接近完全充气状态的充气确保与肠壁接触。 从业者拉回到内窥镜轴上，将肠壁向肠壁的近端开口反向延伸。 褶皱有助于内窥镜前进。

摘要： A balloon access device for use with an endoscope is disclosed. A transparent balloon attached to the distal end of the endoscope allows a user to both separate collapsed intestinal tissue and visualize the path of the endoscope without administering insufflation gas to the collapsed area of a patient. The attachment of the balloon to the endoscope is achieved by the various embodiments of the balloon access device disclosed herein.
