摘要： The present invention provides a catheter for extraction that can efficiently extract blood flowing in coronary sinus from coronary artery through coronary vein and has the same operability as catheters used in conventional PCI. The present invention also provides a catheter for extracorporeal circulation that can lessen an introduction number of devices for blood access as little as possible and reduce further the burden to a patient, in addition to the same operability as the catheters used in the conventional PCI. The catheter for extraction is equipped with blood extracting lumen in an inside and equipped with a hub at a proximal end portion, and when a minimum sectional area to a circumferential direction of the blood extracting lumen is referred to as S1 and immersion side length is referred to as L1, an equivalent diameter D1 satisfies the formula defined by D1=(4×S1)/L1 and the equivalent diameter D1 is at 1.80 mm. The catheter for extracorporeal circulation also has blood extracting lumen extending from the distal end to the proximal end and blood return lumen extending from the proximal end of the catheter to a fixed length distal end.
摘要翻译：本发明提供一种用于提取的导管，其可以有效地从冠状动脉通过冠状静脉提取在冠状动脉窦中流动的血液，并且具有与常规PCI中使用的导管相同的可操作性。本发明还提供一种用于体外循环的导管，除了与常规PCI中使用的导管相同的可操作性之外，其可以尽可能少地减少用于血液通过的装置的引入数量，并且进一步减轻对患者的负担。用于提取的导管在内部配备有血液提取腔，并且在近端部配备有轮毂，并且当将取血腔的圆周方向的最小截面积称为S1，并且参考浸没侧长度作为L1，当量直径D1满足由D1 =（4xS1）/ L1定义的公式，当量直径D1为1.80mm。用于体外循环的导管还具有从远端延伸到近端的血液提取腔和从导管的近端延伸到固定长度的远端的血液回流腔。

摘要： The present invention aims to provide a contrast agent-removal system and a method of operating the system for efficiently removing the contrast agent which is cause of the renal function impairment. The system of the present invention includes a blood suction catheter which can be placed into the coronary sinus, a column for removing a contrast agent from the drawn blood, a blood drawing circuit for directing the blood into the column, a blood pump for controlling an amount of the drawn blood, a blood return circuit for returning the blood from which the contrast agent is removed to a patient's body and a device for measuring a blood suction pressure. In the method of operating the system, the blood is drawn with the blood suction catheter placed into the coronary sinus and the drawing blood is contacted with an adsorbent for adsorbing the contrast agent.
