Abstract: A heart valve stent having a section with a heart valve implant and several proximally disposed tissue anchors, also comprising a plurality of anchoring threats, each with a proximate end fastened to the stent or valve and a distal end attached to tissue within a heart chamber to provide tension between the heart chamber tissue and the stent.

Abstract: This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.

Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A preferred embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve portion. The prosthetic valve further comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body. A space is provided between an outer surface of the main body and the ventricular anchor for receiving a native mitral valve leaflet. The prosthetic valve preferably includes an atrial sealing member adapted for placement above the annulus of the mitral valve. Methods and devices for delivering and implanting the prosthetic valve are also described.

Abstract: A prosthetic mitral valve assembly and method of inserting the same is disclosed. In certain disclosed embodiments, the prosthetic mitral valve assembly has a flared upper end and a tapered portion to fit the contours of the native mitral valve. The prosthetic mitral valve assembly can include a stent or outer support frame with a valve mounted therein. The assembly can be adapted to expand radially outwardly and into contact with the native tissue to create a pressure fit. One embodiment of a method includes positioning the mitral valve assembly below the annulus such that the annulus itself can restrict the assembly from moving in an upward direction towards the left atrium. The mitral valve assembly is also positioned so that the leaflets of the mitral valve hold the assembly to prevent downward movement of the assembly towards the left ventricle.

Abstract: A heart valve stent having a section equipped to receive a heart valve implant and several proximally disposed anchoring elements, characterized by several anchoring threads, which with the one end thereof are fastened to the stent, and also with a brace fastening the anchoring threads with the other end thereof to the distal chamber wall to provide tension between the heart chamber wall and the proximally anchored anchoring elements.

Abstract: The invention relates to a catheter (10a), comprising a flexible catheter body (10a) forming at least two hollow spaces (90, 100/110) along the longitudinal extension thereof, characterized in that the catheter body (10a) comprises at least two consecutively arranged sections (20) having sheaths (60) that are arranged between the sections (20) and seal the hollow spaces (90, 100/110) at least in some sections, wherein the one hollow space (90) is designed so it communicates with at least one opening (70) penetrating the catheter wall in each section (20), and the other hollow space (100/110) is equipped to introduce an element (40/50) that brings about a longitudinal change of at least one of the sections (20).

Abstract: A heart valve stent (10) having a section equipped to receive a heart valve implant (30) and several proximally disposed anchoring elements (20), characterized by several anchoring threads (40), which with the one end thereof is fastened to the stent (10), and also with a brace (80) fastening the anchoring threads (40) with the other end thereof to the distal chamber wall to provide tension between the heart chamber wall and the proximally anchored anchoring elements (20).

Abstract: The invention relates to a balloon catheter (1) for the sealing of blood vessels and cardiac chambers with at least one inflatable chamber (20) connected to a first line (10), characterized by a unit (40) adjacent to the at least one inflatable chamber (20), forming a cavity with said chamber (20) into which a vacuum line (30) opens, whereby separator elements (60, 70) are provided between the walls forming the cavity, which is gas-permeable at least in a limited region (50) on the outside thereof, for sucking the balloon catheter (1) to the blood vessel or the cardiac chamber.

Abstract: A perfusion catheter includes at least one perfusion channel and at least two dilation units disposed at a distance from each other at the distal catheter region in the longitudinal extension of the catheter. Both of the at least two dilation units are projected through by the perfusion catheter and form, in an inflated state, an at least practically fluid-tight occlusion with the aortic wall. At least the dilation unit disposed on the proximal side has at least one passage through which an auxiliary catheter can be introduced in a fluid-tight manner. The perfusion catheter may have a working channel with an outlet opening in the region between the two dilation units and through which at least one auxiliary catheter can be introduced for aortic valve ablation.

Abstract: The present invention is distinguished by a perfusion catheter being provided comprising at least one perfusion channel designed as a hollow channel and at least two dilation units disposed at a distance from each other at the distal catheter region in the longitudinal extension of the catheter, both the dilation units being projected through by the perfusion catheter and forming in an inflated state an at least practically fluid-tight occlusion with the aortic wall, of which the dilation units at least said dilation unit disposed on the proximal side is provided with at least one passage through which at least one auxiliary catheter can be introduced aortic valve ablation in a fluid-tight manner and/or the perfusion catheter is provided with a working channel which is provided with an outlet opening in the region between the two dilation units and through which at least one auxiliary catheter can be introduced for aortic valve ablation.

Abstract: An anchoring element including a replacement heart valve for the purposes of intraluminal anchoring of the heart valve element to mammalian hearts, the anchoring element having a small enough initial volume prior to its placement that it can be brought to its point of use using a catheter through a blood vessel and can be expanded there to its functionally correct dimensions. The anchoring element is shaped differently from a cylindrical shape such that it is connected to the aorta at the point of use at least in areas in a form-locked manner. This facilitates an especially good seating of the anchoring element containing the replacement heart valve.
