A device for transluminal implantation or extraction of a substantially tubular, radially selfexpanding stent (27), comprising a central tube (3) surrounded by an exterior tube (5) axially displaceable relative to the central tube (3), and a plurality of axially extending spring members (21) attached to the outer surface of said central tube (3) at the distal end thereof, said members (21) being substantially evenly distributed around the periphery of said tube (3) and capable of outward springing action of their front ends when retracting said exterior tube (5) from the distal end of said central tube (3). |
