摘要:
Implant for influencing the blood flow in arteriovenous deficiencies.The invention relates to an implant (1) for blood vessels, especially for influencing the blood flow in the region of the arteriovenous deficiencies with a wall different filament (2) which are assembled to an essentially tubular braid, which extends in the axial direction of a Proximal to distal.With the different filaments (2) are crossed mutually and form between each other crossing points (3), the implant (1) is such that a deformable in the delivery catheter, assumes a form with reduced diameter and expands at the site of implantation in adaptation to the diameter of the pot SA Ngu\u00edneo,At the proximal end of the distal and \/ or twisted the ends of the filaments are assembled respectively at least in pairs and are joined permanently together, and the ends of the filaments together are formed atraumatic, and being that the filament (2) which are crossed and The United States is respectively directly or indirectly among themselves at the points of intersection (3),Located distant from the ends of the filaments at the tip (10) proximal to the implant (1). In this way, it is guaranteed that the implant (1) after release to dilate also at the proximal end to the walls of the vessel, and the filaments do not view into the vascular lumen.implante para influenciar o fluxo sanguíneo em deficiências arteriovenosas. a invenção refere-se a um implante (1) para vasos sanguíneos, especialmente para influenciar o fluxo sanguíneo na região de deficiências arteriovenosas, com uma parede de distintos filamentos (2), que são reunidos para um trançado essencialmente tubular, que se estende em direção axial de proximal para distal, sendo que o distintos filamentos (2) se cruzam mutuamente e formam entre si pontos de cruzamento (3), o implante (1) é de tal maneira deformável que em um cateter de introdução assume uma forma com diâmetro reduzido e se expande no local da implantação sob adaptação ao diâmetro do
