ABSTRACT:
A small diameter steerable guidewire adapted for use in percutaneous transluminal coronary angioplasty has three segments, each adapted to reside in a separate region of the arterial and coronary anatomy during angioplasty. The proximal segment is adapted to reside proximally of the aortic arch and has high torsional rigidity for enhanced pushability and rotational transmission. An intermediate segment is adapted to reside in the region of the aortic arch and is more flexible than the proximal section while maintaining a high degree of rotation transmission. The distal segment is more flexible than the intermediate segment and is dimensioned to reside from a region proximally of the primary curve of the guidewire to and into the coronary arteries.
