Intravascular guide wire and method for manufacture thereof
First Claim
1. A guidewire comprising:
- an elongate core having a proximal region and a distal region, the distal region of the core having a proximal portion and a distal portion, the distal portion including a distal end, the distal portion comprising a flat ribbon;
an atraumatic tip positioned at the distal end of the elongate core;
a coil disposed over the distal portion of the core, the coil having a distal end positioned proximate the atraumatic tip, the coil extending proximally over the distal region of the elongate core.

Abstract
A guide wire, and a method for the manufacture thereof, having a core and a plastic jacket enclosing the core. The plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material. The distal end of the proximal jacket portion and the proximal end of the distal jacket portion substantially abut each other and are of substantially equal outer diameters so as to form a smooth transition between the proximal and the distal jacket portions. According to another aspect, there is provided a guide wire with a selectively formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion with a hydrophilic coating and a proximal portion without a hydrophilic coating. According to another aspect, there is provided a guide wire having a formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion that is more radiopaque than a proximal portion.
