  • Method for delivering a fluid to the coronary ostia
    Publication number: 20010023334
    Abstract: A catheter system is provided for accessing the coronary ostia transluminally from a peripheral arterial access site, such as the femoral artery, and for inducing cardioplegic arrest by direct infusion of cardioplegic solution into the coronary arteries. In a first embodiment, the catheter system is in the form of a single perfusion catheter with multiple distal branches for engaging the coronary ostia. In a second embodiment, multiple perfusion catheters are delivered to the coronary ostia through a single arterial cannula. In a third embodiment, multiple perfusion catheters are delivered to the coronary ostia through a single guiding catheter. In a fourth embodiment, multiple catheters are delivered to the coronary ostia through a single guiding catheter which has distal exit ports that are arranged to direct the perfusion catheters into the coronary ostia.

  • Antegrade cardioplegia catheter and method
    Patent number: 6090096
    Abstract: A cardioplegia catheter is configured to extend into the ascending aorta with a proximal portion of the shaft extending into a left chamber of the heart through the aortic valve and out of the heart through a penetration in a wall thereof. The cardioplegia catheter has an occlusion member configured to occlude the ascending aorta between the brachiocephalic artery and the coronary ostia. An arterial return cannula delivers oxygenated blood to the arterial system downstream of the occlusion member, while cardioplegic fluid is delivered through a lumen in the cardioplegia catheter upstream of the occlusion member to induce cardioplegic arrest.
