"stent sending device with swiveling stent retainer sheath". The present invention relates to a sending device (1) for sending a stent device (3) which is expandable from a radially reduced sending configuration to a radially expanded deployed configuration. A retainer sheath (4) is disposed over the stent device to hold the stent device in the shipping configuration. a pull line (13) to be pulled is provided to retract the retainer sheath in a roll-up mode so that the retainer sheath is folded over itself providing the radially inner sheath (7) of the retention sheath, a sheath radially outer (8) of the retainer sheath and a bend portion (9) therebetween. the pull line is movable by pulling on it to move the outer sheath over the inner sheath and thus to move the bending portion axially with respect to the stent device to retract the retainer sheath from the stent device to release the stent device for expansion to the unfolded configuration. The pull line extends axially along the stent device and joins the retainer sheath substantially at or beyond an axial end of the stent device in a pre-retracted retainer sheath configuration. the retainer sheath is made of a cold drawn plastic at least along the path of travel of the fold portion in retracting the retainer sheath from the stent device."dispositivo de envio de stent com bainha de retentor girá vel de stent". a presente invenção refere-se a um dispositivo de envio (1) para enviar um dispositivo de stent (3) que é expansível a partir de uma configuração de envio radialmente reduzida para uma configuração desdobrada radialmente expandida. uma bainha de retentor (4) é disposta sobre o dispositivo de stent para manter o dispositivo de stent na configuração de envio. uma linha de puxar (13) a ser puxada é proporcionada para retrair a bainha de retentor em um modo de enrolar de modo que a bainha de retentor é dobrada sobre si mesma proporcionando a bainha radialmente interna (7) da bainha de retenção, uma bainha radi
