A guidewire (10) and methods for making and using the same. The guidewire may include a core wire (22) and a polymer jacket (24) attached to the core wire. The guidewire may be manufactured by advancing the core wire, polymer jacket, and a tooling tube (26) through a heated die (30) assembly so as to heat and compress the polymer jacket onto the core wire. Optionally, the tooling tube may be removed from the jacket after advancing the components through the die assembly.

La présente invention concerne un fil-guide (10) et des procédés de fabrication et d'utilisation de celui-ci. Le fil-guide peut inclure un fil principal (22) et une gaine polymère (24) fixée au fil principal. Le fil-guide peut être fabriqué en faisant passer le fil principal, la gaine polymère et un tube outil (26) à travers un ensemble de matrice chauffée (30) de façon à chauffer et comprimer la gaine polymère sur le fil principal. Le tube outil peut être éventuellement retiré de la gaine, les composants une fois passés à travers l'ensemble de matrice.
