APPARAT ZUR DURCHFUEHRUNG EINER VERLAENGERTEN ANGIOPLASTIE.

摘要

This apparatus comprises a catheter consisting of an inflatable dilatation balloon fixed at the end of an air-intake conduit. This balloon is traversed by a tube (1) opening out beyond the latter and extending over the entire length of the air-intake conduit, this tube being intended to ensure a perfusion of blood, or of physiological fluid, beyond the dilatation balloon during its inflation. The end of this tube, which is opposite this balloon, is connected to a perfusion pump (11) whose functioning is controlled by a control apparatus (17) capable of ensuring the synchronisation of its functioning with the electrocardiogram of the patient to be treated, in order to provide for, in advance of the dilatation balloon, a perfusion of blood, or of physiological fluid conveying oxygen, at a variable flow rate corresponding to the physiological diastolic and systolic phases of the cardiac rhythm of this patient. ��
