The present invention relates to an occlusion device () consisting of a braiding () of thin wires or threads () which is given a suitable form in a molding and heat treatment procedure. The occlusion device () has a proximal retention area () and a distal retention area (), whereby the ends of the wires or threads () converge into a holder () in distal retention area (). A cylindrical crosspiece () is furthermore disposed between the proximal and distal retention areas (). With the objective of providing an occlusion device which positions as flat as possible against the septum at the proximal side of a septal defect in the inserted state, the invention provides for the proximal retention area () of the braiding () to exhibit a completely closed proximal wall () disposed with a continuous surface at the proximal end of the occlusion device () which forms the proximal end () of said occlusion device ().

Occlusion device and method for its manufacture

An anchoring for heart valve prostheses includes a stent framework, for attaching heart valve leaflets to an inner side, and compartmentalization clips, connected with the stent framework at a first end region and having a free second end region. The anchoring exhibits a primary form and reversibly transformable into a delivery form for the minimally invasive introduction into the body of the patient by elastic deformation and/or compression of certain regions or elements. The compartmentalization clips are arcuately shaped between the first and second end regions in the primary form and are elastically foldable such that the compartmentalization clips extend in a flat manner between the first and second end regions in the delivery form. The anchoring has a separation structure connected with the stent framework and the compartmentalization clips to separate the areas of the native leaflets to be treated from the bloodstream when the anchoring implanted.

System for treating, preventing and/or replacing a heart valve, in particular an inflamed, infected, thrombosed or degenerated heart valve

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 medical device for treating a heart valve insufficiency, with an endoprosthesis which can be introduced into a patient's body and expanded to secure a heart valve prosthesis in the patient's aorta. In an embodiment, the endoprosthesis has a plurality of positioning arches configured to be positioned with respect to a patient's aorta and a plurality of retaining arches to support a heart valve prosthesis. The endoprosthesis includes a first collapsed mode during the process of introducing it into the patient's body and a second expanded mode when it is implanted.

Medical device for treating a heart valve insufficiency

A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent () with a prosthetic heart valve () at its proximal end is introducible into a patient's main artery. With the objective of optimizing such a device to the extent that the prosthetic heart valve () can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis () in the patient's ventricle, the device includes a self-expanding positioning stent () introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent () so that the two stents respectively interact in their expanded states such that the heart valve stent () is held by the positioning stent () in a position in the patient's aorta relative the heart valve predefinable by the positioning stent ().

Device for the implantation and fixation of prosthetic 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.

Medical device for treating a heart valve insufficency

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.

The invention relates to a catheter for the transvasculur implantation of prosthetic heart valves, in particular comprising self-expanding anchorage supports (), 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 comprising anchorage supports is temporarily housed in a folded form in a cartridge-type unit () riming 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, 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.
