The extension arm is fixed at the distal end of the distal section of the guiding sheath or is configured to be moved along the guiding sheath so that it projects in an operation position from the distal end of the distal section, wherein the extension arm has an inner lumen through which a guidewire (17) can be maneuvered and defines a longitudinal axis (15), wherein the catheter system further comprises at least one alignment component (20, 120, 220, 320, 420, 520) having a collapsed state and being configured to expand into an expanded state, wherein the alignment component is attached to the guiding sheath at a pre-defined position within the distal section but proximally from its distal end or the alignment component is configured to be advanced along the guiding sheath to this pre-defined position within the distal section, wherein the alignment component comprises a plurality of struts (21, 28) distributed on the circumference, wherein each strut of the plurality of struts runs at least sectionwise into radial direction and/or inclined with regard to the longitudinal axis in the expanded state thereby producing a force directed radially outwardly and supporting the alignment component on the patient's heart, vasculature and/or implant. Further, a method for the closure of at least one paravalvular leakage (53) is explained.

A process for chemical crosslinking of tissue joining partners including crosslinkable groups, such as free amino groups, by a suitable crosslinking agent under static, quasi-static or periodic pulsatile pressure compression. The compression can be in a defined overlap region for seamless, dense and tight tissue closure. This results in a seamless, homogeneous, and at the same time mechanically stable connection/joining of tissue/tissue components. Seamless connected tissue is provided that includes a piece of tissue having at least two tissue parts overlapping each other and the at least two tissue parts overlapping each other that are materially bonded to each other via crosslinked groups of the tissue.

Method for the production of crosslinked and optionally shaped tissue with selective adjustment of thickness, shape and/or flexibility
A method for chemically crosslinking and optionally shaping (including thickness reduction) substantially non-cross-linked tissue, in particular biological tissue, using a permeable material layer. The method can be used in combination with a stepless pressure load/compression on the tissue, so as to always allow fluid transport into and out of the tissue to be treated under the chemical cross-linking; along the lines of drainage. The method can be carried out under different pressure loads/compressions, in particular in order to specifically influence the resulting tissue properties, and, for example, to bring about a homogeneous thickness distribution of the tissue and/or to deliberately and specifically place inhomogeneities, if desired. Furthermore, the method allows the introduction/imprinting of a consistent three-dimensional shape into the tissue to be treated, e.g. of inhomogeneities in the thickness of the tissue.
