Aggregates for intraluminal insertion of tubular stents and endovascular grafting devices

摘要

An aggregate for transluminal insertion of a tubular stent (1) which, in its placed condition in a vessel in the vascular system, is provided at its periphery with a tubular coating (2) along at least part of its length, the aggregate including an introducer sheath (3) with a stent arranged inside the sheath in a first condition with a reduced diameter, and an extruder device (4) which can be manipulated to release the stent from the introducer sheath, the stent (1) being adapted to expand to a second condition with a larger diameter. The stent is placed in its first condition inside the introducer sheath (3) in direct contact with the inner sheath surface, and the tubular coating (2) is placed in connection with the aggregate so that the coating is not placed on the periphery of the stent until during the release of the stent from the introducer sheath by the expansion from the first to the second condition.
