Abstract
A coupling wire guide generally includes a main body defined by a first wire wound around a safety wire. A first loop is defined by an enlarged revolution of the first wire within a distal portion of the main body. The first loop is sized to receive a previously introduced wire guide for coupling the two wire guides.
Claims17
A coupling wire guide for coupling to a previously introduced wire guide during intracorporeal procedures, the coupling wire guide comprising:
- a main body defined by at least a first wire, the main body extending along a longitudinal axis, the first wire wound around a safety wire to define a plurality of revolutions have a predetermined size and pitch;
- a first loop defined by an enlarged revolution of the first wire within a distal portion of the main body, the first loop sized to receive the previously introduced wire guide therein;
- and
- the first wire, at a position distal to the first loop and enlarged revolution, again forms a plurality of revolutions having the predetermined size, the first wire maintaining the pitch from a position proximal to the first loop to the portion distal to the first loop.

A coupling wire guide for coupling to a previously introduced wire guide during intracorporeal procedures, the coupling wire guide comprising:
- a main body defined by a first wire, a second wire and a third wire, the main body extending along a longitudinal axis, the first, second and third wires coiled in parallel around the longitudinal axis;
- the first wire defining a first loop at a distal portion of the main body;
- the second wire defining a second loop at the distal portion of the main body;
- and
- the third wire defining a third loop at the distal portion of the main body wherein the first, second and third loops do not overlap in the longitudinal direction,
- wherein the first, second and third wires are coiled at a predetermined pitch that is maintained from a location proximal to the first loop to a location distal to the third loop.
