    摘要： An occlusive medical device such as a vascular implant includes a terminal portion including a first plurality of strut segments that are each joined together at a distal end thereof to form a closed end of the frame, an intermediate portion including a second plurality of strut segments, the second plurality of strut segments including a greater number of strut segments than the first plurality of strut segments, and a main portion including a third plurality of strut segments, the third plurality of strut segments including a greater number of strut segments than the second plurality of strut segments. The occlusive medical device may have an expanded configuration in which the second plurality of strut segments and the third plurality of strut segments together form a plurality of cells.

    摘要： An implantable medical device is adapted to be implanted at an implantation site within the vasculature and is capable of being implanted at the implantation site within the vasculature at more than one position relative to the implantation site. This may include a relative axial position and/or a relative rotational position. The implantable medical device includes an expandable frame that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, and one or more radiopaque markers disposed relative to the expandable frame such that fluoroscopic imaging of the implantable medical device during deployment provides an indication of a position of the implantable medical device relative to the implantation site. The implantable medical device may be a replacement cardiac valve such as a replacement aortic valve, for example.

    摘要： A method of making a vascular occlusion device may include cutting a tubular member to form an expandable frame including a first hub integrally formed with the expandable frame adjacent a first end of the expandable frame, and a plurality of longitudinally-oriented struts extending in a direction opposite the first end; heat-setting the expandable frame to define an expanded configuration of the expandable frame; sliding a constrainment member over the plurality of longitudinally-oriented struts, the constrainment member being formed using additive manufacturing technology; fixedly securing the constrainment member to the plurality of longitudinally-oriented struts to define a second hub of the expandable frame; and cutting the plurality of longitudinally-oriented struts adjacent the constrainment member and opposite the first end relative to the constrainment member.
