In an embodiment, the annular inner member can be formed by coextruding a first and second material. The first material includes a fold, and the second material radially spaces the different parts of the fold from each other during fabrication and provides support for maintaining the tubular structure. The second material is removed once the coextrusion process is complete.Type: GrantFiled: July 17, 2019Date of Patent: October 17, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Erik Bulman, Duy Nguyen, Kim D.

Patent number: 11779196Abstract: 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.Type: GrantFiled: September 23, 2019Date of Patent: October 10, 2023Assignee: VISUALIZATION BALLOONS, LLCInventor: Boris Reydel
