Abstract
A coupling wire guide structured to be slidably coupled to a previously introduced wire guide during intracorporeal procedures. The coupling wire guide includes a main body and a tip portion, the tip portion having first, second and third sections. The first section is connected to the main body, while the second section interconnects the first and third sections. The third section defines an axial passageway having a distal opening and a proximal opening. The axial passageway is sized to receive the previously introduced wire guide therein. The second section includes a strip sized to leave an open area in communication with the proximal opening.

A coupling wire guide for coupling to a previously introduced wire guide in intracorporeal procedures, the coupling wire guide comprising:
- a main body having a distal end;
- a tip portion securely connected to the distal end of the main body, the tip portion including first, second and third sections oriented along a longitudinal axis, the first section connected to the main body, the second section interconnecting the first and third sections, the third section defining an axial passageway having a distal opening and a proximal opening, the axial passageway sized to receive the previously introduced wire guide therein;
- and
- the second section including a strip extending axially and circumferentially that defines a complementary axially and circumferentially extending opening in communication with the proximal opening, the strip following a curved path between the first and third sections, the strip extending circumferentially around the longitudinal axis less than 360 degrees and having a circumferential width less than 180 degrees, the natural unbiased configuration of the tip portion defining the axially and circumferentially extending opening.
