Abstract: An occlusion device having a lumen defined therethrough and a saddle narrower than saddles of prior occlusion devices or stents to allow provision of an occlusion element with respect to a portion of the saddle to occlude flow of materials through the saddle. The inner diameter of the narrowed saddle may be 6 mm or less. The occlusion element may be formed from a material which plugs a portion of the occlusion device lumen extending through the saddle and/or which restrains a portion of the saddle from expanding thereby occluding flow of materials therethrough. The remainder of the saddle and/or inwardly facing surfaces of at least one retention member extending outwardly along an end of the saddle may be configured to promote tissue ingrowth, such as by remaining uncoated.
