    Abstract: A catheter system is provided for accessing the coronary ostia (176, 180) transluminal from a peripheral arterial access site, such as the femoral artery, and for inducing cardioplegia arrest by direct infusion of cardioplegia solution into the coronary arteries. In a first embodiment, the catheter system is in the form of a single perfusion catheter (20) with multiple distal branches (24, 26, 28) for engaging the coronary ostia (176, 180). In a second embodiment, multiple perfusion catheters (82, 84) are delivered to the coronary ostia (176, 180) through a single arterial cannula (104). In a third embodiment, multiple perfusion catheters (112, 114, 116) are delivered to the coronary ostia (176, 180) through a single guiding catheter (126). In a fourth embodiment, multiple catheters (140, 142, 144) are delivered to the coronary ostia (176, 180) through a single guiding catheter (130) which has distal exit ports (134, 136, 138) that are arranged to direct the perfusion catheters into the coronary ostia (176, 180). In each embodiment, the catheters (20) are equipped with an occlusion means (30, 50) at the distal end of the catheter (20) for closing the coronary ostia (176, 180), and isolating the coronary arteries from the systemic blood flow.

    Abstract translation: 提供导管系统用于从外周动脉进入部位(例如股动脉)进入腔内的冠状动脉口(176,180),并通过将心麻痹液直接输注到冠状动脉中诱导停搏。 在第一实施例中,导管系统是具有用于接合冠状动脉口(176,180)的多个远端分支(24,26,28)的单个灌注导管(20)的形式。 在第二实施例中,多个灌注导管(82,84)通过单个动脉插管(104)输送到冠状动脉口(176,180)。 在第三实施例中,多个灌注导管(112,114,116)通过单个引导导管(126)输送到冠状动脉口(176,180)。 在第四实施例中,多个导管(140,142,144)通过具有远端出口(134,136,138)的单个引导导管(130)输送到冠状动脉口(176,180),所述导向导管设置成引导 灌注导管进入冠状动脉口(176,180)。 在每个实施例中,导管(20)在导管(20)的远端配备有闭塞装置(30,50),用于封闭冠状动脉口(176,180),并将冠状动脉与全身血液隔离 流。
