摘要： The invention relates to a vascular access device (10) for implantation onto a vessel wall, the access device comprising an tubular structure (12) to provide an access passage into the vessel via a hole in a vessel wall, a connector arrangement (20; 21) for attaching the tubular structure at said hole in the vessel wall, and a membrane structure (16A; 16B) sufficiently flexible to be collapsed for insertion through said hole and to be expanded to lie at least partially against an inner vessel surface thereby to surround the hole. The membrane structure comprises a membrane aperture (18) to provide a passage from inside the vessel into the tubular structure. The vascular access device further comprises a closing mechanism capable of closing the membrane aperture while the membrane structure is expanded against said inner vessel surface. There is also provided a method of implanting a vascular access device.

摘要： An oxygenator (10) for an extracorporeal ventilation system comprises a gas passage and a blood passage arranged to allow gas exchange of an oxygenation gas supply with blood via a gas-blood interface (34). The gas passage leads from a gas inlet zone (28) via the gas-blood interface (34) to a gas exhaust zone (40). The blood passage leads from a blood inlet (12) via the gas-blood interface (34) to a blood outlet (14). The oxygenator comprises a supply gas distribution arrangement (26, 28A, 28B). This allows the oxygenation gas supply to be modulated differently for different interface regions of the gas-blood interface. The oxygenator can be used to remove or reduce the formation of gaseous microemboli bubbles.
