  • Publication number: 20200038179
    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.

  • Patent number: 10327895
    Abstract: The invention relates to a medical prosthesis, and in particular a heart valve substitute comprising a pliant tubular conduit mounted on a resilient annular frame and tethered to a non-perforating anchor within the right or left ventricle of the heart, wherein the pliant tubular conduit is a reciprocating mechanical member that is compressed by pressurized working fluid within the ventricle during systole.

  • Publication number: 20190167421
    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.

  • Patent number: 10258471
    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).
