The invention relates to a catheter for the transvascular implantation of prosthetic heart valves, in particular including self-expanding anchorage supports (10), which allow a minimally invasive implantation of prosthetic heart valves. The aim of the invention is to reduce the risk to the patient during the implantation. To achieve this, according to the invention a prosthetic heart valve with anchorage supports is temporarily housed in a folded form in a cartridge-type unit (4) during the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system (1), which includes a flexible region (9) that can be guided through the aorta. Actuating elements (2, 3) run through the interior of the hollow guide system, said elements 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.

Catheter system for implantation of prosthetic heart valves

A catheter is described 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 with 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 includes 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.

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.

Occlusion device for occluding an atrial auricula and method for producing same

An occlusion device and a production process for it are described. The occlusion device consists of a mesh or braiding of at least one wire or thread wherein the occlusion device has been given a suitable design using a reshaping and/or heat-treatment process, is self-expandable, and is configured for secure anchoring in an atrial appendage of the left or right atrium of a heart. 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.

Methods of implanting an endoprosthesis

The disclosure relates to a method of manufacturing a medical implant or structures for a medical implant. Disclosed is an improved occluder (), which does not damage the surrounding body tissue. In one embodiment, a method of manufacturing aD fabric of strands for forming an occluder is provided. The method comprises intertwining the strands along a length of theD fabric for forming a primaryD fabric structure. The intertwining is non-continuous, i.e. the braiding procedure can be halted, for forming a secondary structure of theD fabric without intertwining.

Catheter for the transvascular implantation of prosthetic heart valves

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.
