ABSTRACT:
A percutaneous transluminal angioplasty or atherectomy catheter is acoustically enhanced by placing at least two ultrasonographically detectable markers, one at the proximal and one at the distal limits of the catheter balloon. The location of the catheter in the artery is thereby correctly positioned by ultrasonographic imaging.
