A medical device with a corrugated shaping ribbon is provided, The corrugated shaping ribbon (34) allows for the medical device, which may be provided in the form of a guide wire (20) or catheter, specifically a crossing guide wire or catheter, to more easily navigate through the sometimes tortuous pathways of body lumens In addition, the corrugations (42) effectively provide 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 (28) extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.

L'invention concerne un appareil médical avec un ruban de forme ondulée. Ledit ruban de forme ondulée (34) permet à l'appareil médical, qui peut être conçu sous forme d'un fil-guide (20) ou d'un cathéter, spécifiquement un fil-guide ou un cathéter de traversée, de naviguer plus facilement à travers des voies parfois tortueuses des lumières du corps. De plus, les ondulations (42) permettent un mécanisme efficace par lequel de l'énergie peut être stockée lorsque la pointe distale de l'appareil médical entre en contact avec une lésion ou autre région d'occlusion d'un vaisseau sanguin. En stockant une telle énergie et en continuant d'appliquer une force, la pointe distale (28) se détend finalement libérant ainsi l'énergie stockée et permettant à la pointe distale d'avancer ou de traverser la lésion.
