  • Publication number: 20170074346
    Abstract: A nozzle plate for an axially damping hydraulic mount having a passage disk with a passage for connecting a work chamber and a balance chamber of a hydraulic mount. The passage disk is rotationally fixable at a first angular position in the hydraulic mount. The nozzle plate also has a cover disk with an aperture that is arranged above the passage at a pre-definable angular position. The passage of the passage disk is bound on one side by the cover disk. The aperture forms an inlet opening into the passage or an outlet opening out of the passage for a fluid damping agent. The cover disk is rotationally fixed such that the aperture is at a second angular position selected from a plurality of different angular positions with respect to the passage disk.

  • Publication number: 20060229714
    Abstract: A covered stent including a stent covered on a first surface by a continuous covering and on a second surface by a discontinuous covering, the discontinuous covering bonded to the continuous covering, the discontinuous covering including first and second rings of material spaced apart such that a region of the second surface is uncovered.

  • Patent number: 7083640
    Abstract: A flexible covered stent having a stent covered on a first surface by a first layer of biocompatible material and on a second surface by both a second and third layer of biocompatible material, the first and second layers and the first and third layers of biocompatible material being bonded to one another through openings in a wall in the stent. The first layer of biocompatible material is longer than both the second and third layers of biocompatible material such that at least a portion of the second surface of the stent is not covered by either second or third layer, imparting flexibility to the stent.

  • Patent number: 6740115
    Abstract: A flexible covered stent includes a stent covered on a first surface by a first layer of biocompatible material and on a second surface by a second layer of biocompatible material, the first and second layers of biocompatible material being bonded to one another through a wall in the stent. The first layer of biocompatible material is longer than the second layer of biocompatible material such that at least a portion of the second surface of the stent is left uncovered, imparting flexibility to the stent. A mid portion of the second surface of the stent can be left uncovered to impart flexibility to the stent similar to that enjoyed by a bare stent.

  • Patent number: 6579314
    Abstract: A portion of a covered stent is encapsulated with ePTFE, so that the unencapsulated portion, which is covered by a single ePTFE covering, imparts an unimpaired flexibility to the stent. One surface of the stent, either the luminal or abluminal surface, is covered by a single continuous layer of ePTFE, while limited regions, preferably near the ends of the stent, of the other surface are also covered by ePTFE. The regions covered by ePTFE on both surfaces become encapsulated when the ePTFE of one layer becomes bonded to second layer. By leaving a middle region of the stent unencapsulated, the stent retains flexibility similar to a bare stent, thereby reducing the loading and deployment forces.

  • Patent number: 6572647
    Abstract: A laser cut stent for transluminal delivery has windows in its cylindrical wall, the windows giving the stent enhanced flexibility during delivery along said lumen. A method of making such a stent involves removing from the wall of a tube enough material to leave the tube wall penetrated in a multiplicity of separate cut lines, in a pattern which permits the tube to expand. The tube is then expanded and then a plurality of tube wall scrap portions are removed from the tube wall between adjacent cut lines, thereby to introduce a plurality of spacings between adjacent stenting zones of the tube wall surface, these remaining after compression of the tube to a configuration to allow it to be advanced along a tortuous bodily lumen. Advantageously, the material of the tube is a shape memory alloy and the tube is for a self-expanding stent.
