COVERED EXPANDABLE STENT

摘要

Covered expandable stent (1)having preferably one or several side branches (2) for inserting into the vascular system by means of an introducer sleeve (11). The covered expandle stent (1) comprises: - a tubular body (4) provided with sutures (5) running along and fixed at spots on the circumference of the inner surface at a number of spaced apart locations in the lengthwise direction of the stent (1), which sutures (5) in a compressed state of the stent form loops extending to the centre of the stent (1), - guide wire(s) (6,7) inserted through the loops keeping the stent (1) in a first compressed state, prior to operation the stent (1) having been further compressed and inserted into the introducer sleeve (11), whereby during operation the stent (1) is pushed out of the introducer sleeve (11) assuming the first compressed state in which the stent (1) is navigable so as to achieve the correct location, the guide wire (6,7) being adapted to be removed thereafter, whereby the stent (1) assumes a fully expanded state in which the loops of the sutures (5) extends around the circumference of the inner surface of the tubular body (4).
