Stent with improved radiopacity and appearance characteristics

摘要: A stent (10) is plated with a high density, radiopaque metal (or alloy) such as gold or tantalum. Specifically, the to sufficient thickness (15) on its longitudinal wires (12) make it clearly in fluoroscopy, but generally circumferential (11) are much lesser (14) so that they not distinctly radiopaque. Before deployed radially outward vessel of human body, very close together implanting physician can easily discern proximal and distal extremities (10). Furthermore, readily has been because longitudinals will separate an increased distance from each other after proper deployment. Still further, if does properly deploy, fluoroscopy indicate there indentation (12A) (12C) one more hence informing he should inflate pressure balloon at end angioplasty catheter further deploy against inner wall vessel. Proper deployment characterized by parallel relationship between opposite (12). Because single outer coating (albeit varying thickness) all surfaces, electrolytic corrosion avoided. may be advantages associated plating greater some others. over surfaces would provide most attractive appearance.
