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.

Abstract: An implantable device having an expandable element, such as a balloon, exerting a radially-outwardly directed anti-migration force to hold the implantable device in place. The implantable device occlusion device may be an occlusion device configured to be inserted through a body passage. The implantable device may include a first component and a second component expandable within a lumen of the first component to exert an antimigration force against the first component. The first component may be an expandable stent coated to resist tissue ingrowth, and the second component may be an expandable balloon configured to exert an anti-migration force against the expandable stent.
