    • The present invention relates to a balloon catheter device (1) intended to be placed within a conduit (2) of a biological flux, for administering a therapeutic composition to luminal walls (3) of said conduit (2), comprising: - an outer catheter (4) and a distal balloon (8) and a proximal balloon (9) around the outer catheter (4), wherein a first segment (10) of the wall of the outer catheter between the distal balloon (8) and the proximal balloon (9) is permeable to the therapeutic composition, a second segment (11) of the wall of the outer catheter between the proximal balloon (9) and the proximal end is permeable to the biological flux; - a hollow cylinder (13) having a wall (14) substantially impermeable to the biological flux, with a first opened end (15) and a second opened end (16), wherein the first opened end (15) is hermetically fitted through the opening (7) of the distal end of the outer catheter, and the second opened end (16) opens in the portion of the lumen of the outer catheter underneath said second segment (11); - at least two inner catheters for respectively inflating the distal and proximal balloons (17,18) and at least one inner catheter for delivering the therapeutic composition (19).
    • 本发明涉及一种旨在放置在生物通量的导管(2)内的气囊导管装置(1),用于将治疗组合物施用于所述导管(2)的腔壁(3),包括:外部 导管(4)和围绕外导管(4)的远端球囊(8)和近端球囊(9),其中外导管的壁的第一部分(10)在远端球囊(8)和近端 气囊(9)对于治疗组合物是可渗透的,外导管壁在近端球囊(9)和近端之间的第二部分(11)可渗透生物通量; - 具有基本上不可渗透生物通量的壁(14)的中空圆筒(13),具有第一开口端(15)和第二开口端(16),其中第一开口端(15)通过 所述外导管的远端的开口(7)和所述第二开口端(16)在所述第二段(11)的下方的所述外导管的内腔部分开口; - 至少两个内导管,用于分别充气所述远端和近端气囊(17,18)和至少一个用于输送治疗组合物(19)的内导管。
