<p>An embolization device for positioning in a blood vessel comprises an elongated wire body (1) which in its unloaded condition has a predetermined shape and during its insertion through a catheter has an elongated shape with a substantially straight centre line (18). In its predetermined shape the wire body has at least one section (4) located between its front and back ends in which the centre line has substantially no curvature. The front end section (2, 2'', 2''') of the wire body is adapted to be frictionally locked to the vessel wall when discharged from the catheter.</p> |
