Device for arranging guidewires around a heart valve
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.
1. 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.
2. A guide wire introduction device according to claim 1 , wherein the second catheter comprises two lumens which are capable of causing guide wires to slide therein.
3. A guide wire introduction device according to claim 1 , 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.
4. A guide wire introduction device according to claim 1 , wherein the second catheter is provided at a distal tip thereof with a radiopaque element.
5. A guide wire introduction device according to claim 1 , wherein the deflection system of the second catheter comprises a wire.
6. A guide wire introduction device according to claim 1 , wherein the first catheter is a catheter with a single lumen.
7. A guide wire introduction device according to claim 1 , wherein the third catheter is provided with a distal deflection system.
8. A guide wire introduction device according to claim 1 , wherein the third catheter is orientated such that in use an end of the third catheter is curved in an opposite direction with respect to a direction in which an end of the second catheter is curved.
9. 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.
10. A guide wire introduction device according to claim 9 , wherein the at least two lumens are capable of causing guide wires to slide therein.
11. A guide wire introduction device according to claim 9 , wherein the second catheter is provided at a distal tip thereof with a radiopaque element.
12. A guide wire introduction device according to claim 9 , wherein the deflection system of the second catheter comprises a wire.
13. A guide wire introduction device according to claim 9 , wherein the first catheter is a catheter with a single lumen.
