Title:
【発明の名称】血管内超音波画像と案内カテーテル位置との回転方向相関関係
Document Type and Number:
Japanese Patent JPH11506628
Kind Code:
A
Abstract:
Apparatus and method are described for introducing an imaging catheter to the coronary vasculature. A guiding catheter is introduced so that the distal end of the guiding catheter engages a coronary os. The distal end of the guiding catheter is shaped so that a mark on the distal end is oriented in a predetermined orientation relative to the coronary vasculature. An imaging catheter is then introduced through the guiding catheter and an image of the mark is produced with the imaging catheter while in the guiding catheter. In this manner, the relative orientation of the produced image and the coronary vasculature is known.
