Abstract: A stent includes a fluid-permeable stent body having longitudinally separated proximal and distal stent ends. The stent body has inner and outer stent body surfaces. The stent body defines at least one longitudinally extending primary lumen and at least two longitudinally extending secondary lumens laterally spaced from one another with at least a portion of the primary lumen interposed laterally therebetween. The secondary and primary lumens all are at least partially fluid-permeable between the inner and outer stent body surfaces. At least one fluid-impermeable and longitudinally extending berm is located directly laterally adjacent a corresponding secondary lumen. The berm prevents fluid flow laterally between at least a portion of the corresponding secondary lumen and a space laterally opposite the secondary lumen beyond the berm. A method of using the stent in at least partially extending a superior landing zone of an abdominal aortic aneurysm is also described.

Abstract: A flagellated, back-curved guidewire component of the present invention facilitates passage of a balloon catheter through the vasculature. The guidewire may be used in conjunction with commercially available devices. Alternately, the guidewire may come integrated with a balloon catheter, such as a flagellated balloon embolectomy catheter or a flagellated balloon resuscitation catheter. The guidewire can include multiple flexible flagellate disposed at a distal end of an elongate wire configured for passing through the vasculature. The guidewire is configured to self-center in the vasculature.
