    • An expandable endovascular stent comprises a flexible, tubular body (1) with a longitudinal axis, the wall of which is formed by interconnected, closed lattice cells (2) arranged with at least two cells adjacent to each other in the circumferential direction. Filament-shaped lattice material capable of transmitting compressive forces in the axial direction of the filament extends continuously from one lattice cell directly into the lattice cell following in the longitudinal direction. The stent can be expanded from a radially compressed state into a radially expanded state having a larger diameter. In the expanded state of the stent, the pressure transmitting lattice material in several of the lattice cells (2) forms a heart-like or arrowhead-like shape with at least two interconnected diverging, angle .beta. cell sides (5) positioned opposite to and interconnected with at least two mutually converging, angle .alpha. longer cell sides (3). For stability during expansion and compression of a self-expanding stent, the sum of the first angle .alpha. and the second angle .beta. should be in the range of 345.degree. to 360.degree., preferably at 360.degree. to maintain a constant axial stent length.

    • An expandable endovascular stent comprises a flexible, tubular body (1) with a longitudinal axis, the wall of which is formed by interconnected, closed frame cells (2) arranged with at least two cells adjacent to each other in the circumferential direction. Filament-shaped frame material capable of transmitting compressive forces in the axial direction of the filament extends continuously from one frame cell directly into the frame cell following in the longitudinal direction. The stent can be expanded from a radially compressed state into a state having a larger diameter. In the expanded state of the stent, the pressure transmitting frame material in several of the frame cells (2) forms a heart-like or arrowhead-like shape with two interconnected shorter cell sides (5) positioned opposite to and interconnected with two mutually converging longer cell sides (3).

    • An endovascular graft prosthesis for arrangement at or in the vicinity of a bifurcation in the arterial system of a patient, e.g. for the purpose of repairing an aneurysm or the aortic bifurcation comprises a substantially tubular main body for location in the principal upstream arteria above the bifurcation such as th aorta and substantially tubular legs joining said main body in a bifurcation and extending into each of two branch arteries such as the iliac arteries. The main body (8) is substantially bag-shaped with an open proximal upstream end and a distal downstream bottom region in which two outlet openings (9, 10) are provided and is attachable to the inner side of the principal arteria (2) by means of an expandable stent device (11). The legs are made as separate expandable leg stent devices (15, 16) which may be introduced in a collapsed condition through the branch arteries and into the outlet openings (9,10) of the main body by means of guide wires (13,14) to engage against the rim of the corresponding outlet opening to provide a leakage-free bifurcated graft prosthesis.

    • A closure prosthesis and transcatheter delivery system are disclosed, wherein the closure prosthesis seals across an opening of a fluid passageway within a living body. The closure prosthesis is a flexible disk including a flexible ring and diaphragm having a plurality of hollow flexible wire segments attached thereto. Delivery of the closure prosthesis is accomplished using a hollow sheath and a pusher catheter slidable within the sheath, wherein filaments are looped through the wire segments to releasably connect the disk to the pusher catheter. The disk is resiliently compressed within the sheath and, upon release therefrom, the disk resiliently expands into a larger, unrestrained shape. Tension applied to the filaments resiliently bends the wire segments so that they may be drawn through the opening of the defect. Upon releasing the filaments from the disk, the wire segments resiliently expand to trap the disk in place to seal across the opening.

    • An assembly for positioning an embolization coil (4) in the vascular system. The assembly includes a guidewire having a relatively flexible distal section (6), which has a central core (7) and a threading coil (10), the distal turns (11) of which are arranged with such mutual spacing (12) that the embolization coil can be threaded in and out of the threading coil. The distal end section of the guidewire is manufactured with an elongated, rotationally symmetrical member, such as cylindrical member (13), and the peripheral surface of the member is provided with a bonding layer (25). Then the distal turns of the threading coil are positioned in the desired helical shape on the external side of the member, and the bonding layer is activated so that the distal turns are fixed to the member in this shape. The cylindrical member (13) has an outer diameter which is a fraction smaller than the inner diameter of the embolization coil (4) and has a length which is longer than the extent in the axial direction of the guidewire of at least three of the distal turns (11) of the threading coil. The distal turns of the threading coil are fixed to the external side of the member, so that the thread provided is geometrically stable and smooth-running.
