CORONARY SINUS ACCESS CATHETER WITH FORWARD-IMAGING |
摘要 |
A coronary access catheter system simplifies the insertion of objects into distal branches of the coronary sinus. The system incorporates a real-time forward-imaging means to view the os and the branches of the coronary sinus. Preferably, the catheter uses near-infrared light as the forward-imaging means, but it could also include ultrasound or electromagnetic transducer. As the image is viewed, the catheter tip can be steered into the coronary sinus os and deflected in a tight radius bend on the distal end to navigate the short radius, right angle turns found in the coronary sinus branches. At that point, a flexible sheath can be placed over the guide catheter or objects such as guidewires can be inserted into channels of the guide catheter. The system consists of a catheter and image acquisition unit, which displays the forward image. |
