摘要: The sealing device (1) includes an elongated body (5) adapted to be introduced into a tube-shaped channel (2) and including fluid placement section (6) arranged between first second annular flow barrier (7, 8). further activation (11) the (8) third (12) (13) at least initiate or accelerate curing of (17). In operation, may displaced along until is placed position where has been ejected by section, activated. Thereby, cured selected locations tube- shaped after ejection fluid.
