A stent includes a flaring portion and a main portion connected to the flaring portion. The main portion includes a plurality of bands of cells spaced apart axially from one another, adjacent bands of cells being intermittently connected to one another. During use, the stent is introduced into a main vessel in a contracted condition and positioned with the flaring portion adjacent an ostium. The flaring portion is flared, and the stent is advanced at least partially into the ostium. The stent is expanded further such that the main portion expands within the branch body lumen and/or the flaring portion expands adjacent the ostium. The main portion compresses axially during at least one of the steps when the stent is expanded, which may enhance conformance of the stent relative to the ostium and/or enhance reinforcement of the ostium.

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, and a single vertical aperture. The single vertical aperture extends from the top surface to the bottom surface, has a size and shape predetermined to maximize the surface area of the top surface and the bottom surface available proximate the anterior and posterior portions while maximizing both radiographic visualization and access to the substantially hollow center, and defines a transverse rim. The body may be non-metallic and may form one component of a composite implant; the other component is a metal plate disposed on at least one of the top and bottom surfaces of the body.

An implant that has a predefined ratio of load bearing surface area to the overall size of the implant body and specifically to the surface area of a centrally located opening of a vertical aperture which connects to a center void area or passage defined by the implant body shape. This invention discloses a critical ratio or balance between loading of contained graft material through the hollow center or central passage of the implant and the implant's frictional load bearing or contact area with e.g., adjacent vertebral bones. Application of this invention to a spinal implant provides an improved integration and integration rate of the graft material or the fusion of the adjacent vertebral bone structures. The ratio between implant load bearing surface area and implant central opening area maximizes implant internal volume and allows a large passage disposed medial laterally to allow for radiographic verification of fusion growth.
