Abstract: The invention relates to a radially expandable vessel support which comprises a multitude of zigzag shaped annular elements (2, 3), interconnected in a flexible way by bending elements. Said annular elements define a vessel support (1) with a proximal and a distal end and a longitudinal axis, where the zigzag shaped annular elements (2, 3) are arranged side by side across the longitudinal axis of the vessel support (1), where zigzag shaped annual elements (2, 3) are linked to at least one further annual element by means of at least one bending element which is comprised either of a pair of S-shaped bars (20, 21) or of a pair of bow shaped bars (4, 5) which are located diametrically on the circumference and whose apertures show into opposite directions.

Abstract: The invention relates to a device for closure of defect openings in the human or animal body, which device, in a first state, can assume an elongate shape with a high ratio of length to transverse extent, and, in the implanted state, has a shape with a lower ratio of length to transverse extent, the device being deformable in the radial direction and comprising first arrangements with which the device, in the implanted state, supports itself elastically against the margin of the opening which is to be closed and thereby centers itself approximately within the opening. The device includes second arrangements which, in the implanted state, bear with positive engagement on opposite sides of the tissue surrounding the opening which is to be closed.

Abstract: Spiral implant for organ pathways, in particular for blood vessels, which is formed from a primary spiral made of metal or a primary tube made of an elastic synthetic material whose anterior end is closed and whose cross-section at a distance of 0.5 to 2 mm from the other end of the primary spiral or primary tube is modified for a distance of 0.01 to 10 mm in order to make it possible to reposition the implant. The force required to displace the primary shape on the guide wire serving as an insertion aid amounts to 0.5N to 10N. The invention describes an implant (1) which can be used in vascular surgery or vascular radiology in order to achieve selective blood vessel occlusion. Insertion of the implant (1) into a blood vessel is brought about by means of an insertion catheter (16), with the implant being held in a rectilinear shape by a guide wire (14) slid therein.
