Band-shaped occlusion means

An implant system for treating an arteriovenous malformation comprising an occlusion unit, with the occlusion unit comprising several subunits, with the subunits comprising a framework having shape memory properties and being formed from wire or produced by laser cutting, wherein the framework is constructed of one or more struts and the occlusion unit being provided with a first stretched arrangement suited for transportation by means of a catheter and a second expanded arrangement after exit from the catheter, wherein the occlusion unit takes on a three-dimensional shape in the second expanded arrangement of said occlusion unit, characterized in that:

• a covering is located between the one or more struts of the framework of the occlusion unit;
• and
• the framework of the occlusion unit comprises a central axial spine and the one or more struts attached thereto, wherein the axial spine can be supported during placement navigation by means of the catheter and for subsequent release of the framework in the arteriovenous malformation in a stretched state by an additional supporting wire which can be removed after release of the occlusion unit;
• wherein
• the one or more struts intersect with the axial spine at a first end and a second end of each strut, with the first end of each strut intersecting the axial spine and secured to the axial spine at a respective first point of intersection, and with the second end of each strut intersecting the axial spine and secured to the axial spine at a respective second point of intersection.
