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 is described. The filter may include a body formed from an elongate member. The body may include loops encircling an axis extending along the length of the body. The body may be sized to be implanted into a body lumen. The body may be capable of transitioning from a collapsed state to a deployed state. The filter may include a first group of a plurality of members positioned around at least one loop of said body. At least a portion of the plurality of members may be oriented towards the axis. The plurality of members may be arranged to capture and/or lyse particulates of a selected size and/or to inhibit the particulates from passing through the body. Methods of making, deploying, and retrieving the same are described.
