Abstract
A stent is a device that is adapted to be implanted into narrowed portions of hollow vessels of a body. The stent (1) comprises a stent body (2) that has at least two different wall thicknesses (WE, WH). The different wall thicknesses result in different flexibility characteristics of the stent in the longitudinal direction. Thus the stent according to the invention prevents irritations of the wall of the vessel in the area of the implanted stent, whereby the risk of restenosis in said area can be reduced considerably.
Claims27
A stent apparatus for stenting, comprising:
- a stent body having a web structure with a plurality of neighboring cells, said neighboring cells including a plurality of first cells and at least one second cell,
- said at least one second cell having a different wall thickness than said first cells, a transition being formed between said first cells and said at least one second cell, said transition being stepped, and
- said stent having a constant inner diameter along its length.
The stent apparatus of 2, wherein
- said different wall thickness of said at least one second cell comprises a greater wall thickness than said first cells.
A method for stenting comprising:
- providing a stent apparatus comprising a stent body having first and second end portions, and a main portion, said main portion having a greater wall thickness than said first end portion, said stent body having a constant inner diameter along its length;
- percutaneously delivering said apparatus to a treatment site within a patient;
- and
- expanding said stent apparatus into contact with said treatrent site.
