Abstract

An endoluminal device can be configured for precise positioning during deployment within a vessel. The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device.

First claim

What is claimed is:

1. A method of placing endoluminal devices, comprising:
advancing a distal portion of an elongate body of a catheter system through the vasculature of a patient, the catheter system including the elongate body having a plurality of identical endoluminal devices disposed thereon in a compressed state and an outer sheath positioned over the plurality of endoluminal devices, each of the endoluminal devices defining a longitudinal axis and comprising:
a first circumferential member disposed at a distal end of the first endoluminal device, the first circumferential member comprising a repeating pattern of a first outward apex connected to a first inward apex connected to a second outward apex connected to a second inward apex, the amplitude of the second outward apex being less than that of the first outward apex;
a second circumferential member disposed proximally from the first circumferential member along the longitudinal axis; and
a plurality of bridge members, each bridge member separately connecting the first circumferential member with the second circumferential member, every second inward apex being coupled with a first end of one of the bridge members of the plurality of bridge members;

retracting the outer sheath while maintaining the position of the elongated body to deploy a first endoluminal device of the plurality of endoluminal devices within a first blood vessel; and
retracting the outer sheath while maintaining the position of the elongated body to deploy a second endoluminal device of the plurality of endoluminal devices within a second blood vessel, the second endoluminal device being separate from and unconnected to the first endoluminal device when deployed, wherein when in the deployed state, the first and second endoluminal devices have a difference in outer diameter of at least 2.5 mm.

2. The method of claim 1 , wherein when in the deployed state, the first and second endoluminal devices have a difference in outer diameter of at least 3.0 mm.

3. The method of claim 1 , wherein each of the endoluminal devices of the plurality of endoluminal devices are expandable in outer diameter from 1.5 mm to 5.0 mm.

4. The method of claim 1 , wherein each of the endoluminal devices of the plurality of endoluminal devices are expandable in outer diameter from 3 mm to 6 mm.

5. The method of claim 1 , further comprising deploying one or more endoluminal devices of a second plurality of endoluminal devices in a blood vessel of the patient, each of the endoluminal devices of the second plurality being identical and being a different size than the endoluminal devices of the first plurality.

6. The method of claim 5 , wherein only the two different sized pluralities of endoluminal devices are used to hold plaque against vessel walls in blood vessels throughout a leg of the patient from a hip to an ankle of the leg.

7. A method comprising performing an angioplasty with a drug coated balloon followed by the method of placing endoluminal devices of claim 1 .

8. The method of claim 1 , wherein the first circumferential member of each of the endoluminal devices of the plurality of endoluminal devices comprises a first sinusoidal ring and wherein the second circumferential member of each of the endoluminal devices of the plurality of endoluminal devices comprises a second sinusoidal ring, wherein the first sinusoidal ring and the second sinusoidal ring each have a dual amplitude.

9. The method of claim 1 , wherein at least one bridge member of the plurality of bridge members of each of the endoluminal devices of the plurality of endoluminal devices comprises at least one anchor.

10. The method of claim 9 , wherein at least one bridge member of the plurality of bridge members of each of the endoluminal devices of the plurality of endoluminal devices further comprises an eyelet configured to hold a radiopaque marker.

11. The method of claim 10 , wherein the eyelet is positioned between a first anchor of the at least one anchor and a second anchor of the at least one anchor.

12. A method of placing endoluminal devices, comprising:
advancing a distal portion of an elongate body of a catheter system through the vasculature of a patient, the catheter system including the elongate body having a plurality of delivery platforms, and a plurality of identical endoluminal devices disposed thereon in a compressed state and an outer sheath positioned over the plurality of endoluminal devices and the plurality of delivery platforms, each of the endoluminal devices positioned in one of the plurality of delivery platforms, each of the endoluminal devices defining a longitudinal axis and having at least two circumferential members spaced apart along the longitudinal axis, each circumferential member comprising:
a repeating pattern of a first outward apex connected to a first inward apex connected to a second outward apex connected to a second inward apex, the amplitude of the second outward apex being less than that of the first outward apex;

retracting the outer sheath while maintaining the position of the elongated body to deploy a first endoluminal device of the plurality of endoluminal devices within a first blood vessel; and
retracting the outer sheath while maintaining the position of the elongated body to deploy a second endoluminal device of the plurality of endoluminal devices within a second blood vessel, wherein when in the deployed state, the first and second endoluminal devices have a difference in outer diameter of at least 2.5 mm.

13. The method of claim 12 , wherein when in the deployed state, the first and second endoluminal devices have a difference in outer diameter of at least 3.0 mm.

14. The method of claim 12 , wherein each of the endoluminal devices of the plurality of endoluminal devices are expandable in outer diameter from 1.5 mm to 5.0 mm.

15. The method of claim 12 , wherein each of the endoluminal devices of the plurality of endoluminal devices are expandable in outer diameter from 3 mm to 6 mm.

16. The method of claim 12 , further comprising deploying one or more endoluminal devices of a second plurality of endoluminal devices in a blood vessel of the patient, each of the endoluminal devices of the second plurality being identical and being a different size than the endoluminal devices of the first plurality.

17. The method of claim 16 , wherein only the two different sized pluralities of endoluminal devices are used to hold plaque against vessel walls in blood vessels throughout a leg of the patient from a hip to an ankle of the leg.

18. A method comprising performing an angioplasty with a drug coated balloon followed by the method of placing endoluminal devices of claim 12 .

19. The method of claim 12 , wherein each circumferential member of the at least two circumferential members comprises a sinusoidal ring having a dual amplitude.

20. The method of claim 19 , wherein each circumferential member of the at least two circumferential members is connected to another circumferential member of the at least two circumferential members by at least one bridge member.

21. The method of claim 20 , wherein the at least one bridge member comprises at least one anchor.

22. The method of claim 21 , wherein at least one bridge member comprises an eyelet configured to hold a radiopaque marker.

23. The method of claim 22 , wherein the eyelet is positioned between a first anchor of the at least one anchor and a second anchor of the at least one ancho
