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.

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 at 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.

The invention relates to an anchoring system for heart valve prostheses which can be implanted by introduction via the aorta without any major surgical operation. With the heart valve prosthesis according to the invention it shall be achieved that this can be safely and quickly guided through the aorta toward the heart, and can be fixed there. With this, hook-shaped elements are secured to the commissures of the heart valve prosthesis the hooks of which are guided in an outward direction through the heart valve prosthesis material.

Anchoring system for implantable heart valve prostheses

The present invention provides for a device for holding a substrate in an exposure system. In the exposure system, the substrate is positioned on a table movable in the X and Y coordinates of an X, Y plane, and the exposure system provides a metering assembly between a table surface and the substrate to adjust the distance and to align the substrate in relation to an exposure optics, from where a corpuscular radiation is directed right-angled onto a substrate surface, corresponding to the Z coordinate. The device for holding the substrate includes two mounting plates aligned parallel to the X, Y plane, adjusted upon the table in a direction to the exposure optics and with different distances to the table surface, the first mounting plate of which being directly connected to the table. The second mounting plate is connected with the first mounting plate through at least one holding device, and has a bearing plane for the substrate being designed on that side of the second mounting plate turned to the exposure optics.
