Abstract:
1. A stent, comprising: a material having structure to provide three-dimensional visualization of a surrounding tissue when said stent is inserted into said tissue and viewed under an imaging beam, said stent having: a single coating layer selected from a group consisting of: a hydrophilic polymer, a hydrophobic polymer, and a fatty acid polymer; a density enhancing radiologic opacifier embedded into said single coating layer, said single coating layer and said embedded opacifier material together providing a first Hounsfield image density suitable for viewing under a first image modality used during device insertion into a patient, wherein said density enhancing radiologic opacifier material is configured to elute from said single coating layer so as to provide a second Hounsfield image density suitable for viewing under a second image modality used for subsequent visualization of surrounding tissue, and wherein the second Hounsfield image density is less than about 1200 Hounsfield Units; and a restenosis inhibiting drug embedded into said single coating layer.
