1. A method of inserting a cannula into the ascending aorta and infusing cardioplegic solution therein, the cannula having an elongated cannula body with an angled bend formed in a distal end thereof, an occlusion balloon positioned at the distal end of the elongated cannula body, and an outer sheath surrounding the elongated cannula body and dimensioned for axial movement there along, the method comprising:

  • inserting the elongated cannula body into a body cavity;

    positioning the distal end of the elongated cannula body over the ascending aorta;

    incising the aorta in the center of a pursestring suture previously formed in the ascending aorta;

    inserting the distal end of the elongated cannula body into the ascending aorta and inflating the occlusion balloon therein;

    drawing the pursestring suture around the elongated cannula body;

    advancing the outer sheath until the distal end thereof is in contact with the ascending aorta thereby compressing a portion of the ascending aorta between the distal end of the outer sheath and the occlusion balloon; and

    infusing a cardioplegic solution into the ascending aorta proximate to the occlusion balloon so that the cardioplegic solution perfuses into the coronary arteries.
