Abstract
A guide wire introduction device for positioning at least one guide wire around a heart valve. The device includes a first catheter provided with a distal deflection system, a second catheter inserted inside the first catheter, at least one lumen capable of causing a guide wire to slide therein and provided with a distal deflection system for deflecting the end thereof through an angle greater than 90°, and a third catheter inserted inside the first catheter. The third catheter has a guide wire capturing device therein and is provided with a distal deflection system.
Claims13
A guide wire introduction device comprising:
- a first catheter which is provided with a distal deflection system,
- a second catheter which can slide inside the first catheter and exit from an opening of the first catheter, the second catheter comprising at least one lumen, each of the at least one lumen having at least one guide wire sliding therein, the second catheter further being provided with a distal deflection system for deflecting the end thereof through an angle greater than 90°, and
- a third catheter which can slide inside the first catheter and exit from the same opening of the first catheter from which the second catheter exits, and which has a guide wire snaring device therein;
- wherein the at least one guide wire is configured to completely surround a native valve.
A guide wire introduction device comprising:
- a first catheter which is provided with a distal deflection system,
- a second catheter which can slide inside the first catheter, the second catheter comprising at least one lumen, each of the at least one lumen having at least one guide wire sliding therein, the second catheter further being provided with a distal deflection system for deflecting the end thereof through an angle greater than 90°, and
- a third catheter which can slide inside the first catheter, which has a guide wire snaring device therein and which is provided with a distal deflection system for deflecting the end thereof in a direction opposite to the direction in which the second catheter is deflected;
- wherein the at least one guide wire is configured to completely surround a native valve;
- and
- wherein the at least one lumen comprises at least two lumens, and the at least two lumens of the second catheter terminate so as to face in substantially mutually opposite directions.
