An implant can include a support component, a cover component, and a valve component. The valve component can be operable to permit flow through the implant. The implant can be delivered on a catheter, with one of the ends of the implant being selectively expanded to permit temporary occlusion of a vessel while delivering a material through the valve component to a downstream target region. The other end of the implant can thereafter be released such that the implant occludes the vessel, or the implant can be removed from the vessel entirely.
