Estimating the term…
Metal foils, wires, and seamless tubes with increased mechanical strength are provided. As opposed to wrought materials that are made of a single metal or alloy, these materials are made of two or more layers forming a laminate structure. Laminate structures are known to increase mechanical strength of sheet materials such as wood and paper products and are used in the area of thin films to increase film hardness, as well as toughness. Laminate metal foils have not been used or developed because the standard metal forming technologies, such as rolling and extrusion, for example, do not lend themselves to the production of laminate structures.
An implantable medical material comprising of a self-supporting monolithic structure composed of a plurality of layers of at least one biocompatible metal material;
An implantable medical device, comprising a self-supporting monolithic structure having a plurality of layers of at least one biocompatible metal material, at least one of the plurality of layers consisting of a radiopaque biocompatible metal material and an interface region defined at a boundary between adjacent pairs of the plurality of layers, the interface region having a local concentration of grain boundaries that is higher than a local concentration of grain boundaries within the remainder of the at least one biocompatible metal material of the plurality of layers, and wherein the interface region further comprises a microroughness having a peak-to-valley depth of between about 5 μm to about 65 μm between adjacent pairs of the plurality of layers.
