Abstract: The invention relates to a device for the extraction of a spiral from a blood vessel with said device comprising a guide wire (3) which bends back on itself in its distal region where it forms into an arched structure and thus an anchoring part. The free end (7) of the guide wire (3) points towards the proximal end of said wire (3) and can be hooked onto the spiral (8) that is to be extracted.

Abstract: The invention relates to a liquid embolizate, especially for the occlusion of vascular malformations. Said liquid embolizate is made of: a) 20-80% v/v of an occlusion mixture which contains a zein emulsion in aqueous ethanol, b) 10-40% v/v of a radiopaque contrast medium in liquid form and c) 10-40% v/v of ethanol. The components (a), (b) and (c) are separated and are mixed immediately before application in order to form a homogeneous emulsion. The invention also relates to a method for the production of said embolizate, the use thereof, in addition to a medical kit containing said embolizate.

Abstract: Method for the production of a modeling system (1) for aneurysms involving the steps: Local heating of a first hollow body which is suited for conducting liquid and is comprised, at least in one or more partial areas, of a flexible, thermoplastically deformable material. The local heating is effected on at least one of the partial areas until the thermoplastically deformable material softens. The invention also involves subjecting this first hollow body to the action of pressure that is great enough to cause a deformation at the heated location, whereby the size of the deformation is determined by the duration of the pressure applied and/or by the intensity of the pressure applied.
