摘要： The invention relates to an implant (1) for blood vessels, in particular to influence the flow of blood in the area of arteriovenous malformations, said implant having a wall consisting of individual filaments (2) forming, in essence, a tubular braiding extending in axial direction from the proximal to the distal end, wherein the individual filaments (2) cross one another and form points of intersection (3), and wherein the implant (1) being deformable in such a manner that, when accommodated in an insertion catheter, it is shaped so that its diameter is reduced and can be expanded at the implantation site adapting to the diameter of the blood vessel, and wherein the filament ends at the proximal and/or distal end of the braiding are each brought together at least in pairs and connected with each other permanently, and with the filament ends connected with each other being shaped so as to be atraumatic, and wherein the filaments (2) crossing one another at the points of intersection (3) located distally from the filament ends are directly or indirectly connected with each other at the proximal end (10) of the implant (1). It is ensured in this manner that the implant (1) when released expands up to vessel walls also at the proximal end and the filament ends do not protrude into the vessel lumen.

摘要： The invention relates to a device for the implantation of occlusion helixes (3) that can be separated by electrolysis in blood vessels and body cavities, especially aneurysms (12), said device comprising an insertion aid (4), at least one occlusion helix (3) that is distally arranged in relation to the insertion aid (4) and at least one electrolytically corrodible severance element (2), with at least one stabilization helix (5) being arranged between severance element (2) and occlusion helix (3) and said stabilization helix (5) being connected with the occlusion helix (3) by an electrically isolating adhesion layer (7) such that the occlusion helix (3) becomes isolated from the voltage when an electrical voltage is applied to the severance element (2). In this way, the current density in severance element (2) is further increased so that, on the one hand, shorter severance times are achieved and, on the other, the connection between the occlusion helix (3) and one of the stabilization helixes (5) used to stabilize the implant is significantly simplified compared to the known laser welding method according to prior art.

摘要： The invention relates to a device for the implantation of occlusion helixes (3) into body cavities or blood vessels, in particular aneurysms (12), with at least one occlusion helix (3) comprising a plurality of windings and being movably arranged in longitudinal direction within a catheter (1), and one securing means (9) passing at least partially through the lumen of the occlusion helix (3), with said securing means (9) being fixed in its end areas inside the occlusion helix (3) and consisting of at least two wires with each of the wires having a diameter of less than 0.02 mm. The use of a plurality of wires of relatively small diameter for the securing means (9) enables high flexibility and at the same time high tensile strength properties to be attained. In this way, two opposed characteristics can be achieved which at first glance appear to be mutually exclusive.
