In a stent intended for implantation in a living body and having a bridge structure in which at least two bridges are coupled to one another at at least one node region on at least one of the bridges near the node region, the section modulus of the bridge varies along the length thereof, and the stresses arising at the node region upon deformation of the stent are distributed in the longitudinal direction of the bridge.

Stent having a bridge structure

The present invention relates to an aneurysm stent for implantation into a living body, in particular for treatment of aneurysms, in order to implant the stent in the compressed state in a vessel and expand the stent after positioning it in the vessel, having a grid or mesh structure and at least one membrane () or a plurality of membranes () for covering at least one or more stent cells () in the grid or mesh structure, thereby matching the permeation characteristics of the stent structure to the particular characteristics of the aneurysm.

The invention relates to a spreader structure () for introducing into a hollow organ, comprising spreader rods (), which radiate from a first connection section () essentially in the longitudinal direction () of the spreader structure () up to a second connection section (), are distributed around the periphery of the spreader structure () and can be placed against a wall of a hollow organ by means of radial expansion. The aim of the invention is to provide a spreader structure (), which is versatile and cost-effective to produce. To achieve this, the spreader rods () have at least one zone () running in the longitudinal direction, which has a reduced flexural strength in comparison to neighboring zones (). The invention also relates to the use of said spreader structure, to a spreader device and to a method for positioning a spreader structure.
