The present invention discloses devices, systems and methods for increasing blood pressure in a blood vessel by introducing an anchor within that traps a particle capable of increasing in volume as it is exposed to blood flow. As the particle increases in volume, it serves to decrease the cross sectional area of the blood vessel, resulting in decreased blood flow and increased blood pressure. This invention may be used to arterialize blood vessels in the venous system to prepare them for an exposure to arterial pressures.
La présente invention concerne des dispositifs, des systèmes et des procédés permettant d'augmenter la tension dans un vaisseau sanguin en y introduisant un ancrage qui retient une particule dont le volume peut augmenter lorsqu'il est exposé à un flux sanguin. En augmentant de volume, la particule contribue à réduire la section transversale du vaisseau, ce qui provoque une diminution du flux sanguin et une augmentation de la tension. Cette invention convient pour "artérialiser" les vaisseaux sanguins du système veineux en vue d'une exposition à des pressions artérielles.
