<p>This invention is related to a catheter body embedded with at least one balloon which is inflated for guiding a needle cannula through a side port. Once a distal end of the catheter body is near a puncture zone, the balloon is inflated against the coronary sinus wall, pushing the distal end of catheter body against the puncture zone and stabilizing it. Then, the needle cannula is advanced piercing the interventricular septum at the puncture zone.</p> |
