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.
Abstract: The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular an orthogonally delivered transcatheter prosthetic valve having a tubular frame with a flow control component mounted within the tubular frame and configured to permit blood flow in a first direction through an inflow end of the valve and block blood flow in a second direction, opposite the first direction, through an outflow end of the valve, wherein the valve is compressible to a compressed configuration for introduction into the body using a delivery catheter for implanting at a desired location in the body, said compressed configuration having a long-axis oriented at an intersecting angle of between 45-135 degrees to the first direction, and expandable to an expanded configuration having a long-axis oriented at an intersecting angle of between 45-135 degrees to the first direction, wherein the long-axis of the compressed configuration of the valve is substantially parallel to a length-wise cylindrical axis of

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).
