Stent
First Claim
1. Stent for splinting and/or keeping open a hollow organ, consisting of a tubular body having a diameter which can be changed through axial displacement of the ends of the body relative to each other, wherein the body comprises at least three stent sections comprising different cross-sections which can be expanded irrespectively of each other, comprising a woven, braided tubular web and one or more phase-shifted helices in one or more planes which are connected to each other via at least two elastic tubular sections which do not contain meshes or helices and further wherein the body is formed, in an unloaded expanded state, from a first stent section having a first diameter, a second stent section having a second diameter and a third stent section having a third diameter, wherein the at least two elastic tubular sections comprises a first elastic tubular section connecting said first stent section to said second stent section, and a second elastic tubular section connecting said second stent section to said third stent section.

Abstract
A stent (10) for transluminal implantation comprises a first, second and third stent section (11, 12, 13) for splinting and/or keeping open a hollow organ which are connected to each other via elastic tubular sections (14, 15). The stent (10) combines at least three different stent designs in one stent and can therefore be adjusted to the motion behavior of a hollow organ in an improved fashion (FIG. 1).
