    600585, 604525
  • Abstract:
    A medical device, such as a medical guidewire, having a portion including an inner zone of material and an outer peripheral zone of material surrounding the inner zone of material. The inner zone of material has a first coefficient of thermal expansion and the outer peripheral zone of material has a second coefficient of thermal expansion less than the first coefficient of thermal expansion, wherein at an operating temperature the outer peripheral zone of material opposes expansion of the inner zone of material such that the outer peripheral zone of material exerts a compressive stress on the inner zone of material.

  • US Patent:
    8152742, Apr 10, 2012
  • Filed:
    May 1, 2006
  • Appl. No.:
    11/414993
  • Inventors:
    Hancun Chen - Maple Grove MN, US
  • Assignee:
    Boston Scientific Scimed, Inc. - Maple Grove MN
  • International Classification:
    A61B 5/00
    A61M 25/00
    A61F 11/00
  • US Classification:
    600585, 606108
  • Abstract:
    A medical device with a corrugated shaping ribbon is provided. The corrugated shaping ribbon for the medical device, which may be provided in the form of a guide wire or catheter, specifically a crossing guide wire or catheter, provides a mechanism by which energy can be stored as the distal tip of the medical device engages a lesion or other area of occlusion within a blood vessel. By storing such energy and continuing to apply force, eventually the distal tip extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.
