An intracorporeal device includes an elongate tubular member. The tubular member can comprise one or more materials that have superelastic and/or shape memory characteristics. The tubular member can comprise one or more deformable zones and one or more elastic zones. The deformable zone(s) can comprise material(s) that are less elastic than the material in the elastic zone(s). The deformable and elastic zones can contain different materials or they can contain the same or similar materials that have been treated in order to change the elasticity or type of elasticity of one of the zones relative to the other zones, creating different elasticity between the elastic and the deformable zones. The intracorporeal device can be, for example, a guidewire, a catheter or any other intracorporeal device that can include an elongate tubular member. |
