Abstract: A catheter is disclosed for the transvascular implantation of prosthetic heart valves, e.g., including self-expanding anchorage supports, to reduce the risk to the patient during the implantation. Accordingly, a prosthetic heart valve comprising anchorage supports is temporarily housed in a folded form in a cartridge-type unit during the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system, which comprises a flexible region that can be guided through the aorta. Actuating elements run through the interior of the hollow guide system, permitting sections of the cartridge-type unit to be displaced radially about their longitudinal axis and/or laterally in a proximal direction, thus allowing individual sections of the anchorage support and the associated prosthetic heart valve to be sequentially released.

The occlusion device comprises a proximal retention region on a proximal end of the occlusion device a distal retention region and a central region between the proximal retention region and said distal retention region and wherein the occlusion device has a closed distal end without a holder, and wherein the occlusion device is at least partly of essentially spherical form, and hollow.

Abstract: A self-expanding occlusion device for occluding an atrial auricula in the heart of a patient includes a braiding of thin wires or threads given a suitable profile form by means of a molding and heat treatment procedure. The occlusion device includes a proximal retention area, a distal retention area and a center section. The occlusion device holds securely in the atrial auricula of a patient in its expanded and implanted state without damaging the tissue of the patient's heart. The proximal retention area has a flanged area which positions at the inner walls of the atrial auricula when the occlusion device is in an expanded state in the atrial auricula to be occluded, and forms a force-fit connection with the inner walls of the atrial auricula, thus holding the implanted and expanded occlusion device in the atrial auricula, whereby the distal retention area closes the opening in the atrial auricula.

Abstract: An occlusion device includes a braiding of thin wires or threads tapering to the diameter of a catheter used for an intravascular implantation/explantation procedure and having a proximal retention area, a distal retention area at which ends of the wires or threads converge into a holder, and a cylindrical crosspiece interposed between the proximal retention area and the distal retention area, whereby the two retention areas are positioned on two sides of a shunt to be occluded in a septum following implantation while the crosspiece transverses the shunt. The holder exhibits a head section at its free end having an eyelet as a cross-hole which can be gripped and held in form-fit fashion by an implantation/explantation instrument. A surgical instrument having such a holder includes gripper tongs with gripping jaws which open and close by a push/pull system, and which force-fit grips the head section of the holder.

Abstract: An occlusion device and manufacturing includes of thin wires or threads made from a shape-memory material. In the expanded state, the occlusion device exhibits a proximal and a distal retention area as well as a cylindrical crosspiece interposed therebetween. Because the proximal retention area of braiding exhibits a form which flares toward the proximal end, in the inserted state of the occlusion device, the lateral edge of proximal retention area lies substantially flush with the septum wall and retention area does not protrude past the septum wall. The manufacturing method includes a braiding technique for producing a tubular braiding open to the top and which needs only be provided with a holder for bundling the threads or wires of the braiding at one end, while at the opposite side, the threads or wires of braiding are intertwined from the center thereof.
