Low profile intraluminal medical devices
View Patent ↗A low profile intraluminal medical device includes first, second and third wire members that define arcuate paths having only a single sigmoidal curve. Connectors join the wire members. The medical device can be used by itself or as a component in a medical device that includes other components, such as a prosthetic valve, occluder, or filter.
1. A low profile medical device having a lengthwise axis, a radially compressed configuration and a radially expanded configuration, said low profile medical device comprising:
a first wire member having first and second ends and defining a first arcuate path with a first curve disposed between the first and second ends, the first arcuate path comprising only a single sigmoidal curve;
a second wire member having third and fourth ends and defining a second arcuate path with a second curve disposed between the third and fourth ends, the second arcuate path comprising only a single sigmoidal curve;
a third wire member having fifth and sixth ends and defining a third arcuate path with a third curve disposed between the fifth and sixth ends;
a first connector connecting the first, third and fifth ends; and
a second connector connecting the second, fourth and sixth ends and spaced from the first connector on said lengthwise axis of said medical device;
wherein substantially no portion of said medical device is disposed on a first transverse axis of said medical device opposite the first, third and fifth ends and substantially no portion of said medical device is disposed on a second transverse axis of said medical device opposite the second, fourth and sixth ends when said medical device is in said radially expanded configuration.
2. The low profile medical device of claim 1 , wherein the second connector comprises a separate member attached to the second, fourth and sixth ends.
3. The low profile medical device of claim 1 , wherein the first connector comprise a separate member attached to the first, third and fifth ends.
4. The low profile medical device of claim 1 , wherein the first curve is disposed substantially opposite the second curve.
5. The low profile medical device of claim 1 , wherein the first, second and third wire members are formed of nitinol.
6. The low profile medical device of claim 1 , wherein the first, second and third wire members are formed of stainless steel.
7. A low profile medical device having a lengthwise axis, a radially compressed configuration and a radially expanded configuration, said low profile medical device comprising:
a first wire member having first and second ends and defining a first arcuate path with a first curve disposed between the first and second ends, the first arcuate path comprising only a single sigmoidal curve;
a second wire member having third and fourth ends and defining a second arcuate path with a second curve disposed between the third and fourth ends, the second arcuate path comprising only a single sigmoidal curve;
a first connector connecting the first and third ends;
a second connector connecting the second and fourth ends and spaced from the first connector on said lengthwise axis of said medical device; and
a third wire member extending from the first connector to the second connector and defining a third arcuate path with a third curve disposed between the third and fourth ends, the third arcuate path comprising only a single sigmoidal curve.
8. The low profile medical device of claim 7 , wherein the second connector comprises a separate member attached to the second and fourth ends.
9. The low profile medical device of claim 8 , wherein the first connector comprises a separate member attached to the first and third ends.
10. The low profile medical device of claim 7 , wherein the first curve is disposed substantially opposite the second curve.
11. The low profile medical device of claim 7 , wherein the first, second and third wire members are formed of nitinol.
12. The low profile medical device of claim 7 , wherein the first, second and third wire members are formed of stainless steel.
13. A low profile medical device having a lengthwise axis, a radially compressed configuration and a radially expanded configuration, said low profile medical device comprising:
a first series of at least three wire members, each wire member of the first series of wire members defining first and second ends and an arcuate path comprising only a single sigmoidal curve;
a second series of at least three wire members, each wire member of the second series of wire members defining first and second ends and an arcuate path comprising only a single sigmoidal curve;
a first connector connecting the first ends of the wire members of the first and second series of wire members; and
a second connector connecting the second ends of the wire members of the first and second series of wire members, the second connector spaced from the first connector on said lengthwise axis of said medical device.
14. The low profile medical device of claim 13 , wherein the second connector comprises a separate member attached to the second ends of the wire members of the first and second series of wire members.
15. The low profile medical device of claim 14 , wherein the first connector comprises a separate member attached to the first ends of the wire members of the first and second series of wire members.
16. The low profile medical device of claim 13 , wherein the second connector is integrally formed with the second ends of the wire members of the first and second series of wire members.
17. The low profile medical device of claim 16 , wherein the first connector is integrally formed with the first ends of the wire members of the first and second series of wire members.
18. The low profile medical device of claim 13 , wherein a sigmoidal curve defined by a wire member of the first series of wire members is disposed substantially opposite the sigmoidal curve defined by a wire member of the second series of wire members.
19. The low profile medical device of claim 13 , wherein the wire members of the first and second series of wire members are formed of nitinol.
20. The low profile medical device of claim 13 , wherein the wire members of the first and second series of wire members are formed of stainless steel.
