  • Publication number: 20140074229
    Abstract: A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent (10) with a prosthetic heart valve (11) 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 (11) can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis (11) in the patient's ventricle, the device includes a self-expanding positioning stent (20) introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent (10) so that the two stents respectively interact in their expanded states such that the heart valve stent (10) is held by the positioning stent (20) in a position in the patient's aorta relative the heart valve predefinable by the positioning stent (20).

  • Publication number: 20120236400
    Abstract: The invention relates to a method for producing an optical assembly, comprising at least two optical functional surfaces arranged in a fixed positional relationship to one another on a common supporting structure, wherein by means of a processing machine, in various process steps, at least two optical functional surfaces and at least one reference structure having a defined and measurable relative position to the optical functional surfaces are produced. The supporting structure remains rigidly connected to the processing machine until said process steps have been completed, and wherein the optical functional surfaces are then measured relative to the at least one reference structure, and any deviation from a target shape and target position is determined, after which said process steps are repeated at least once with modified actuation of the processing machine. The invention further relates to an optical device comprising an optical assembly produced in this way and to a unit for carrying out such a method.

  • Publication number: 20090234443
    Abstract: The invention relates to a catheter for the transvascular implantation of prosthetic heart valves, in particular comprising 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 comprising 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 comprises a flexible region (9) that can be guided through the aorta.

  • Patent number: 7491946
    Abstract: The invention is directed to electrostatic deflection systems for corpuscular beams which can be used particularly in microstructured and nanostructured applications in lithography installations or measuring equipment. According to the proposed object of the invention, the individual electrodes of a deflection system of this kind should permanently have and retain a very exact axially symmetric arrangement relative to one another. In the electrostatic deflection system according to the invention, rod-shaped electrodes are held in an axially symmetric arrangement in an inwardly hollow carrier through which a corpuscular beam can be directed. The carrier is formed of at least two, and at most four, carrier members which are connected to one another.
