摘要
A removable filter for capturing thrombi in a body vessel. The filter has antithrombogenic, echogenic, and radiopaque features. The features of the filter provide for enhanced identifying and reduced endotheliosis in a body vessel of a patient. Generally, the anti-thrombogenic feature is preferably a fibrinolytic coating disposed on the filter to decrease the accumulation of fibrin thereon. The echogenic feature preferably is comprised of marks formed on the filter that give rise to reflections of ultrasound waves during ultrasonography. The radiopaque feature is preferably a polymeric coating, ceramic coating, or noble metal coating applied on the filter for enhanced fluoroscopy.
