Hollow guide wire apparatus catheters |
摘要 |
A catheter guide wire includes an elongate tubular body about which a catheter may be threaded for guidance to a target location in a vasculature passageway of a body. The elongate body includes a proximal end and a distal end, with the distal end being curved. Cuts are formed either by saw-cutting, laser cutting or etching at spaced-apart locations along the length of the body to increase its lateral flexibility, while maintaining its rotational torquability. At least some of the cuts extend through the tubular body to the interior cavity to allow the escape of fluids flowing in the cavity. The distal end of the tubular body includes a sufficient number of cuts to make it more flexible than the remainder of the body.
