The invention relates to a radially expandable stent () comprising a plurality of flexibly interconnected meandering ring elements () defining a stent () having a proximal and a distal end and a longitudinal axis, wherein said ring elements () being arranged side by side along the longitudinal axis of the stent and adjoining ring elements () being attached to each other through connection elements (), wherein connection elements () are arranged between at least two adjoining ring elements (), said connection elements each having at least one expandable expansion element with predetermined breaking point (), wherein the expansion being possible in the longitudinal and/or transverse direction and the predetermined breaking points () only disrupting after the expansion element has been overstretched beyond its maximum expansion point.

Stent

The invention relates to a self-expanding device, particularly an implant, for closing defect openings in the human or animal body, which device, in a first state, has the shape of an elongated tube () with slotted segments and, in a second state, has a shortened shape with formation of at least one open or substantially closed hollow structure () of considerable transverse extent, where in the slotted segments of the tube () form individual webs () that are each connected to adjacent webs (), such that a net-like overall structure is obtained in the second state.

Device for closing defects in the vascular system

The invention relates to a double stent comprising coaxially arranged stents, wherein a first membrane () being arranged between a first inner stent () and at least two outer stents (), and a second membrane () being arranged on the outer stents (), with the membrane ends of the first () and second membrane () being brought together at the ends of the stents () and folded around to the inside of the first stent () and clamped securely under flexible tongues () of the first stent ().

Double stent

The invention relates to a radially expandable vessel support which comprises a multitude of zigzag shaped annular elements (), interconnected in a flexible way by bending elements. Said annular elements define a vessel support () with a proximal and a distal end and a longitudinal axis, where the zigzag shaped annular elements () are arranged side by side across the longitudinal axis of the vessel support (), where zigzag shaped annual elements () 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 () or of a pair of bow shaped bars () which are located diametrically on the circumference and whose apertures show into opposite directions.

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.
