ABSTRACT:
The angiographic catheter includes a long generally flexible portion of a first material, an intermediate portion of the first material and a second material that is more flexible then the first material and a tip portion of the second material. The long body portion has a first exit opening having a stream trajectory directed toward the exit stream trajectory from the tip member exit for stream breakup and mixing at. A reaction exit is directed in the opposite direction of the first exit opening.
The generally long body portion with a curved end portion with a first end curve of generally circular shape about a center that is connected to the end of the long body with a compound curve connected to the end of the first end curve and having a member positioned generally parallel to the long body portion with the distance between parallel members generally less than to the radii of the generally circular shape.
The long body member is generally the long generally flexible portion which is composed entirely of the first material. Approximately first ninety degrees of the first end curve is generally the intermediate portion composed of the first and second material. The rest of the first end curve and the compound curve is composed of the second material. The reaction from the stream exiting the tip member exit is to move the parallel portion back into the first end curve without other movement because of reaction from the streams exiting exits.
