Abstract: A system for mounting a heart valve prosthesis on a catheter shaft, the system having at least two components, each component at least partially enclosing a rotation-symmetrical space tapering along an axis of symmetry, the at least two components being designed in such a way that a relative movement of the at least two components along a longitudinal axis of a heart valve prosthesis to be mounted can take place toward one another and into one another in such a way that a space enclosed jointly by the at least two components is decreased. At least one component has a mandrel, which is oriented centrally in the space enclosed by the component and is located on the axis of symmetry of the rotation-symmetrical space.

Abstract: The invention relates to a method for the production of at least one longitudinal section of a catheter, wherein the method comprises the winding of film, and the film is provided in the form of strips, the film strip is wound in the manner of a screw such that the side edges of the film strip extending in the manner of a thread overlap the film strip, and further a bonded connection is created in the overlapping region such that the longitudinal section has a closed and at least fluid-tight surface. The invention further relates to a catheter produced according to the method, and a device for carrying out the method.

Abstract: A catheter guide wire, especially for percutaneous transluminal coronary angioplasty, comprises an elongated wire shaft of a flexible material having a proximal and a distal end and disposed on the wire shaft at least one radiopaque, sleeve-like marker adjacent to the distal end. The at least one marker is disposed on a core section of the wire shaft, said core section being widened in its diameter relative to the diameter of the adjoining shaft sections.

Abstract: An insertion system (100) for a medical device (10), which is situated in an outer sheath (20) upon insertion, the outer sheath (20) at least regionally encompassing an inner shaft. The outer sheath (20) at least regionally has, at least on its inner side (29) facing toward the medical device (10), a structure (22, 32) which is complementary with an external-peripheral segmented structure (12) of the medical device (10) like a bolt-nut connection.

Abstract: A catheter guidewire (1), preferably for cardiovascular procedures, having a distal end (2) and a proximal end (3) and a one-piece core (10) extending essentially from the distal end to the proximal end. The one-piece core has twisted fibers, preferably glass fibers, which are embedded in the basic material of the core. Also disclosed is a method for manufacturing a catheter guidewire.

Abstract: A body implantable stent is formed of a plurality of strands arranged in two sets of coaxial helices, wound in opposite directions to form multiple crossings. At selected crossings, the adjacent strands are welded to one another, while at the remaining crossings the strands are free for limited movement relative to one another. The welds are formed in patterns that preferably enhance radial strength and rigidity, while having a minimal impact on axial bending flexibility. Preferred weld patterns in this regard include rings or circumferential rows, and helices, particularly with a steeper pitch than that of the strands. Stent fabrication preferably involves resistance welding at the crossings, and use of a tool to reuniformly compress the stent around and against the distal end region of a balloon catheter used later to deliver the stent to a treatment site.
