Abstract: Plicator systems may have two telescoping components that when arranged in an open configuration have one or more windows into which tissue of, for example, a tubular organ may be invaginated. The invaginated tissue may be secured in the window when the plicator system transitions to a closed configuration. Closing the window may act to, for example, clamp, pierce of the tubular organ tissue invaginated into the window, thereby securing the invaginated tubular organ tissue into the window. In some instances, an axially-expanding spring may be disposed between two plicator systems and when this assembly is implanted in a tubular organ, axial expansion of the spring may exert a distending force on the tubular organ, which may stimulate growth of the tubular organ.

Abstract: Embodiments of the present disclosure include an aseptic joint assembly for use in minimally invasive surgical imaging systems implementing a positioning arm. According to some aspects, the aseptic joint assembly includes at least one adaptor having a locking mechanism used to removably attach the adaptor onto an end of the positioning arm of the surgical visualization positioning system and directly or indirectly support at least one or both a display and an imaging device of the visualization system. In some embodiments, controlled rotation about one or more axis can be provided for moving the imaging device via an end effector and in relation to a surgical site. According to additional aspects, a surgical drape can be bonded to at least a portion of an adaptor and is configured to cover at least a portion a length of the positioning arm of the surgical visualization system.
