摘要:
Rotational intravascular ultrasound (IVUS) imaging devices and systems are provided. The IVUS imaging devices include catheters having a rotating drive cable with a transducer disposed at a distal end thereof for imaging a bodily vessel of interest. In some embodiments, a lubricious coating is applied on the drive cable to promote uniform rotation of the drive cable and the transducer. In some embodiments, the drive cable is coated with a polymer layer to promote uniform rotation of the drive cable and the transducer. In some embodiments, radiopaque markers are affixed on the drive cable for accurate placement of the transducer within of the vessel and for accurate measurement of internal dimensions and lesion lengths within the body of the patient.
