Stent for placement in a body tube
First Claim
1. A stent for placement in a body tube, the stent comprising a flexible support structure, the support structure comprising at least two groups of wires meshed together, wherein the at least two groups of wires are of a material having shape memory, and wherein the shape memory of the material of one group of wires is different from the shape memory of another group of wires.

Abstract
A stent for placement in a body tube includes a flexible support structure of wires, wherein the wires are of a material having a shape memory function. The support structure of the stent is composed of wires which have different shape memories. In a method for changing the configuration of a stent of the above-described type which has been placed in a body tube, the stent is subjected over at least portions thereof to a specific application of heat or cold in order to influence the restoring force and/or the geometric shape.
