Title
(EN) LOW-PRIME CARDIOPULMONARY BYPASS CIRCUIT
(FR) CIRCUIT DE DERIVATION CARDIO-PULMONAIRE A FAIBLE NIVEAU D'AMORÇAGE
Abstract
(EN)
The present invention relates to apparatus and methods for passing a patient's blood from his body to a location outside the body and then returning it to the patient, in a manner that reduces inflammation and reduces the dysfunction of the immune and hemostatic systems associated with extracorporeal circulation. In particular, the invention relates to the use of a low-prime cardiopulmonary bypass circuit to effect inhibition of injury to a patient's circulatory system, in order to accomplish such therapeutic prophylaxis.
(FR)
La présente invention concerne un procédé et un dispositif permettant de faire passer le sang d'un patient de son corps à un endroit extérieur à son corps, puis à renvoyer au patient ce sang, d'une façon qui réduise l'inflammation et les dysfonctionnements des systèmes immunitaires et hémostatiques accompagnant toute circulation extracorporelle. L'invention concerne plus particulièrement l'utilisation d'un circuit de dérivation cardio-pulmonaire à faible niveau d'amorçage destiné à prévenir les lésions de l'appareil circulatoire du patient, de façon à mettre en oeuvre une telle prophylaxie thérapeutique.
