    摘要： 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.

    摘要： 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.

    摘要： A support catheter that can puncture a heart septum with a guidewire without buckling and that can access difficult to reach arteries such as carotid or renal arteries from the aorta under difficult circumstances is provided. The support catheter comprises a catheter body having a proximal end, a distal end, and an interior wall surface defining a first lumen extending from the proximal end toward the distal end. A second lumen is disposed between the interior wall surface and an outer surface of the catheter body. A plurality of stiffening members is disposed around the second lumen, the plurality of stiffening members being engageable to selectively stiffen the catheter body. In another configuration, the catheter further comprises a second plurality of stiffening members disposed between the first lumen and the second lumen.

    摘要： A medical guidewire (1) suitable for advancement through a vasculature comprises a core element (2) extending along the length of the guidewire (1), a first coil (6), and a distal end cap (7). The core element (2) comprises a proximal portion (3), an intermediate portion (4), and a distal portion (5). The distal portion (5) is plastically deformable to facilitate steering of the guidewire (1). The first coil (6) is located radially outwardly of the core element (2). The first coil (6) extends along the distal portion (5) and part of the intermediate portion (4).
