Abstract:
A method for external treatment of blood, comprising:providing an occludable extraction graft vessel having an anastomosis end which is anastomosed to an extraction blood vessel, wherein the extraction graft vessel is occluded at its anastomosis end to prevent blood from entering the occludable extraction graft vessel; providing an occludable delivery graft vessel having an anastomosis end which is anastomosed to a delivery blood vessel, wherein the occludable delivery graft vessel is occluded at its anastomosis end to prevent blood from entering the occludable delivery graft vessel; enabling fluid communication between said extraction blood vessel and said occludable extraction graft vessel; enabling fluid communication between said delivery blood vessel and said occludable delivery graft vessel; allowing blood to flow in fluid communication between said occludable extraction graft vessel to a blood treatment device and then to said delivery graft vessel, such that blood flow from said occludable extraction graft vessel first reaches said blood treatment device and then reaches said occludable delivery graft vessel after being treated; and occluding said occludable extraction graft vessel and said occludable delivery graft vessel at their respective anastomosis ends after completion of blood treatment with the blood treatment device.
