Abstract: The present invention relates to an endoprosthesis that is expandable from a contracted configuration to an expanded configuration and that includes a plurality of longitudinally adjacent web rings. Each of the web rings is defined by web elements disposed circumferentially around a longitudinal axis, which are adjoined one to the other at junction bends. A first junction bend in a first web ring is coupled to a second junction bend in a second web ring by a connector which includes three or more struts of essentially equal length that extend circumferentially in essentially parallel directions. The struts of the connector are adjoined in sequence by coupling segments that, in one embodiment of the invention, are arcuate in shape. In another configuration, the connector is a flexible connector that is structured to absorb at least some of the axial and torsional stresses applied to the endoprosthesis.

Abstract: The invention relates to a stent graft, adapted for being inserted into a blood vessel, and to a method for forming a stent graft. The stent graft (1) comprises a first stent (2) comprising a plurality of first rings (4) being connected by at least one first connector, wherein the first stent (2) is arranged at least partly in an inner part of the stent graft (1), a second stent (3) comprising a plurality of second rings (5) being connected by at least one second connector, wherein the second stent (3) is arranged at least partly in an outer part of the stent graft (1), and a graft layer is arranged at least partly between the first stent (2) and the second stent (3), wherein the first stent (2) and the second stent (3) having each a predetermined length and the plurality of first rings (4) and the plurality of second rings (5) are axially arranged along the length such that the plurality of second rings (5) fit into the plurality of first rings (4). In this way, a possibility is provided to avoid the problem of integrity in connection with having as less as possible interaction between the first stent and the second stent and thus to minimize the risks of shear effects.

Abstract: An implantable lumen filter (200) is described. The implantable lumen filter includes a body (202) having a proximal end (202a), a distal end (202b), and a generally tapered outer surface (204). The outer surface is formed by a plurality of struts (206a, 206b). The plurality of struts forms a plurality of apertures (210). The apertures are dimensioned to inhibit and/or to lyse particulates of a selected size from passing through the apertures. The body (202) is transitionable from a collapsed state toward a deployed state. The implantable lumen filter includes an engaging portion (220) having a proximal end (220a) and a distal end (220b). The proximal end of the engaging portion is connected to a distal end of the body. The engaging portion has a generally annular shape and is configured to engage an inner surface of a body lumen.
