Abstract: Endovascular valve formation systems with imaging capabilities and associated devices and methods are disclosed herein. In some embodiments, a valve formation and imaging system can include, for example, (i) a valve formation device configured to access a vessel wall and dissect a portion of the vessel wall to form an autologous valve leaflet and (ii) an imaging device configured to image the vessel wall and components of the valve formation device during a valve formation procedure. In some embodiments, the imaging device is integrated into a distal end portion of the valve formation device. In some embodiments, the imaging device is a separate catheter device positionally coupled to the valve formation device and/or components thereof.

Abstract: The diffuser is constructed primarily of lightweight, roll formed, channeled sheet metal bent into a square by cutting the top and bottom margins at the bends. Each of the corners is then riveted. The top wall is molded fiberglass which can be easily cut to form a central opening of different diameters. The figerglass is held between the bent margins of the sidewall and a bracket riveted to the sidewall. The bottom wall is perforated and riveted to the sidewall. A radial deflector having a central portion and arms extending outward is riveted through one of the perforations in the bottom wall. Each arm has a flat portion and bent up portion. The flat portion is spaced from the bottom wall by means of small resilient tabs.
