Abstract: A prosthetic stent with a tubular wall having local inwardly or outwardly formed elevations. Stents having such elevations have a higher mechanical stability if bend according to the curvature of the body vessels to be supported or repaired. Also a method for manufacturing a stent with such elevations is described.

Abstract: The stent comprises a flexible self-expandable braided tubular wall having a proximal segment having an outer diameter, and a distal segment having an outer diameter smaller than the outer diameter of the proximal segment. An intermediate segment is formed between the proximal and distal segments, which forms a truncated cone of which the base is forming the proximal end of the intermediate segment and of which the top is forming the distal end of the intermediate segment. A covering layer is arranged within the tubular wall.

Abstract: Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Preferred stent designs are provided, as well as preferred manufacturing techniques. Apparatus and methods are also provided for use at a vessel branching. Moreover, embodiments of the present invention may comprise a coating configured for localized delivery of therapeutic agents. Embodiments of the present invention are expected to provide enhanced embolic protection, improved force distribution, and improved recrossability, while reducing a risk of restenosis and thrombus formation.

Abstract: The present invention provides a stent comprising a tubular flexible body having a wall with a web structure that is expandable from a contracted delivery configuration to deployed configuration. The web structure comprises a plurality of neighboring, interconnected, web patterns, each web pattern composed of adjoining webs. Each adjoining web comprises a central section interposed between two lateral sections, forming concave or convex configurations. Embodiments of the present invention comprising curvature for tracking tortuous anatomy and reducing localized restoring forces are provided. Methods of using stents in accordance with the present invention are also provided.

Abstract: The invention relates to a procedure as well as a device for introducing an endoprosthesis into the distal end of a catheter by means of which the endoprosthesis is introduced into a vessel for implantation therein and is released to undergo self expansion by moving the tip of a catheter axially relative to the distal end of an outer catheter. An embodiment of the proposed device comprises a hollow cylindrical housing designed to receive the endoprosthesis, a piston axially displaceable therein which can be brought into engagement with the endoprosthesis, and a nose section arranged at one end of the housing, said nose section being provided with a recess tapering in the direction of an opening, and by means of said recess the endoprosthesis supplied by the piston may be introduced, with compressed diameter and in elongated form, into the distal end of the catheter replaceably arranged on the nose section.

Abstract: A body compatible device including an elongate filament substantially uniform in lateral cross-section over its length and having multiple fibers having high tensile strength embedded in a polymeric material. The polymeric material may be melted onto the fibers, and the filament may have an elongate polymeric case surrounding the filament. The body compatible device may be a stent of a tubular latticework.

Abstract: The endoprosthesis is inserted under tension in a recess of a flexible inner catheter and secured by means of a tube-shaped outer catheter. To release the endoprosthesis into a vessel, the outer catheter is pushed back over the recess. The recess is formed by a connector piece that connects a tip to a piece of tubing of the inner catheter. The inner catheter can be designed with a smaller outer diameter in the region of the recess than was previously the case with at least the same flexibility and resistance to buckling.

Abstract: A catheter with a self-expanding stent of a permeable mesh of stiff intersecting fibers is provided. A tubular outer catheter shaft holds the stent under tension at its distal end and from which the stent can be released for placement. A displaceable inner catheter inside the tubular outer catheter shaft supports the stent axially at its proximal end. In order to release the stent, the outer catheter shaft is retracted with respect to the inner catheter. A process for producing this catheter is also described. The stent is secured by gripping it at its proximal end in such a way that it forms a permeable mesh cone that expands automatically together with the stent and has a radius that increases gradually to the radius of the relaxed stent. The stent is securely anchored on the inner catheter with the help of the mesh cone.

Abstract: The stent delivery device has an elongated sheath with a self-expandable stent placed in contracted condition within the distal area of the sheath. An elongated core is arranged in the sheath for relative longitudinal motion between core and sheath, and drive means are arranged between the core and the stent. Scratch protection tubular means comprise a reinforcement ring secured in the sheath and surrounding the distal end portion of the stent when the stent is in contracted condition in the sheath and a tube of thermoformable material heat shrunk over the proximal end portion of the stent and over the core.

Abstract: A catheter with a radially self-expanding cylindrical vascular support made of a permeable mesh of crossed stiff fibers is disclosed. The catheter has a tubular outer catheter shaft and an inner catheter to which the vascular support is fixed. The tubular outer catheter shaft is axially movable with respect to the inner catheter.

Abstract: A weft yarn changer on a projectile loom has a pivoted changer member (1) for at least two yarn transfer elements (2) each in the form of a slide rod (2a) and a yarn gripper (21). Slide bars for the yarn transfer elements (2) are provided on the changer member (1) and are connected by at least one lightweight plastics holder to a tube effective as a drive shaft of the changer member or as a pivot spindle. The inventive weft yarn changer yields reduced actuation times.
