Patent

CA 2575103

This invention includes a highly torqueable, pushable guidewire with a relatively stiff proximal (preferably in one embodiment), stainless steel (SS) section and kink resistant nitinol medial to distal section attached to a shapeable SS, in one embodiment, (such as a SS ribbon) distal tip. The very distal SS tip will have the ability to be shaped by the end user in order to facilitate entry into the chosen vessels.

L'invention porte sur un fil-guide à fort pouvoir de transmission de couple et de poussée présentant (de préférence, dans une exécution) une extrémité proximale relativement raide d'acier inox, et une partie médiane non vrillable de nitinol fixée à une extrémité distale déformable d'acier inox (dans une exécution sous la forme d'un ruban d'acier inox). Ladite extrémité distale présente la capacité d'être déformée par le dernier utilisateur pour pouvoir faciliter sa pénétration dans un vaisseau sélectionné.
