Publication number: 20230233313Abstract: Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The method may include positioning the stent in an undeployed configuration through an access site in a wall of a first body lumen. In some cases, the method may include retracting an outer sheath proximally and past an anchoring component disposed at a distal portion of an inner tubular member based on positioning the stent. A distal portion of the stent may be disposed between the anchoring component and the outer sheath while the stent is in the undeployed configuration. The method may further include deploying the distal portion of the stent from the outer sheath and within the first body lumen and expanding a proximal portion of the stent from within the outer sheath such that upon fully exiting the outer sheath, the proximal portion expands to a deployed configuration within a second body lumen.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventors: Siddhi K.
