摘要:
an arrangement for storing a self-expanding stent-like device (3) includes a container (1) for storing the stent-like device (3) and a stent delivery system disposed in the container (1) and comprising an outer tube (6) ) and an axially movable inner shaft (4) relative to the outer tube (6). the container (1) comprises an interior space (2) and a stent passage opening (20; 20 '). the distal end (21) of the outer tube (6) is connected to the stent passage opening (20; 20 '). a ring-like insert portion is located in the stent passage opening (20; 20 '). the inner shaft (4) extends through the insert portion and comprises a retainer (5) to prevent axial movement of the stent-like device (3) relative to the inner shaft (4). when the stent-like device (3) is stored in the interior space (2) of the container, a proximal end of the stent-like device is compressed to a diameter smaller than one diameter of the insertion part and is held radially compressed by the insertion. the stent-like device (3) is safely stored inside the container (1) and can be prepared for implantation by continuously pulling the inner shaft (4), which carries the stent-like device (3) to inside the outer tube (6) and detaches the container administration system (1).uma disposição para armazenamento de um dispositivo semelhante a stent autoexpansível (3) inclui um recipiente (1) para armazenar o dispositivo semelhante a stent (3) e um sistema de administração de stent disposto no recipiente (1) e compreendendo um tubo externo (6) e um eixo interno (4) axialmente móvel relativo ao tubo externo (6). o recipiente (1) compreende um espaço interior (2) e uma abertura de passagem de stent (20; 20?). a extremidade distal (21) do tubo externo (6) é conectada à abertura de passagem de stent (20; 20?). uma parte de inserção de formato semelhante a anel é localizada na abertura de passagem de stent (20; 20?). o eixo interno (4) se estende através da parte de inserção e compreende um retentor (5) pa
