Abstract

An intraluminal device may be used at a bifurcation to anchor in an afferent vessel, allow perfusion to efferent vessels, and act as scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm. An intraluminal device may include a first side; a second side opposite the first side across a longitudinal axis of the intraluminal device; a proximal section configured to anchor in an afferent vessel; a distal section comprising a first wing and a second wing wherein, in an expanded state, the first wing extends from the first side to the second side and the second wing extends from the second side, through an opening of the first wing, and to the first side.

Claims

1. A method of delivering an intraluminal device comprising:

positioning the intraluminal device within a body vessel while in a compressed state, the intraluminal device comprising (i) a proximal section, (ii) a distal section having (a) a first wing including first base struts connected to each other by a first end strut and (b) a second wing including second base struts connected to each other by a second end strut, and (iii) at least two junctures between the proximal section and the distal section, wherein the first wing and the second wing are fixedly connected to each other only at the at least two junctures;

expanding the intraluminal device from the compressed state to an expanded state in which (i) the first base struts extend from different ones of the at least two junctures and along a first side of the distal section and the first end strut is on a second side of the distal section, substantially opposing the first side, (ii) the second wing extends through an opening in the first wing, and (iii) the second base struts extend from different ones of the at least two junctures and along the second side and the second end strut is on the first side.

2. The method of claim 1, wherein the intraluminal device is positioned within the body vessel while within a sheath, and wherein the expanding comprises withdrawing the sheath.

3. The method of claim 1, wherein the expanding comprises expanding the proximal section radially outwardly against a wall of an afferent vessel.

4. The method of claim 1, wherein the expanding comprises positioning the distal section to abut walls of efferent vessels.

5. The method of claim 1, wherein, after the expanding, the intraluminal device does not cross a central flow path from an afferent vessel to efferent vessels.

6. The method of claim 1, wherein the expanding the intraluminal device comprises expanding the distal section at an aneurysm.

7. The method of claim 6, wherein the expanding the intraluminal device comprises expanding the distal section to span an ostium of the aneurysm.

8. The method of claim 6, wherein the expanding the intraluminal device comprises expanding at least a portion of the distal section to extend within the aneurysm.

9. The method of claim 6, further comprising delivering an implant through the distal section and into the aneurysm, whereby dislodging of the implant out of the aneurysm is inhibited by the distal section.

10. The method of claim 6, wherein, after the expanding, flow into or out of the aneurysm is at least partially diverted.

11. A method of delivering an intraluminal device comprising:

positioning the intraluminal device in a body vessel, the intraluminal device comprising;

a proximal section, the proximal section having a central longitudinal axis;

a distal section having (i) a first wing including first base struts, the first base struts extending from a first side of the distal section and (ii) a second wing including second base struts, the second base struts extending from a second side of the distal section, substantially diametrically opposing the first side, the first base struts being connected to each other by a first end strut of the first wing, the second base struts being connected to each other by a second end strut of the second wing;

at least two junctures between the proximal section and the distal section, the first wing and the second wing being fixedly connected to each other only at the at least two junctures, wherein each of the first base struts extends from a different one of the at least two junctures and each of the second base struts extends from a different one of the at least two junctures, each of the first base struts being between the first end strut and a corresponding one of the at least two junctures, each of the second base struts being between the second end strut and a corresponding one of the at least two junctures;

expanding the intraluminal device, such that the second wing extends transverse to the central longitudinal axis from the second side to the first side through an opening in the first wing, such that the first end strut is on the second side and the second end strut is on the first side.

12. The method of claim 11, wherein the intraluminal device is positioned in the body vessel while within a sheath, and wherein the expanding comprises withdrawing the sheath.

13. The method of claim 11, wherein the expanding comprises expanding the proximal section radially outwardly against a wall of an afferent vessel.

14. The method of claim 11, wherein the expanding comprises positioning the distal section to abut walls of efferent vessels.

15. The method of claim 11, wherein, after the expanding, the intraluminal device does not cross a central flow path from an afferent vessel to efferent vessels.

16. The method of claim 11, wherein the expanding the intraluminal device comprises expanding the distal section at an aneurysm.

17. The method of claim 16, wherein the expanding the intraluminal device comprises expanding the distal section to span an ostium of the aneurysm.

18. The method of claim 16, wherein the expanding the intraluminal device comprises expanding at least a portion of the distal section to extend within the aneurysm.

19. The method of claim 16, further comprising delivering an implant through the distal section and into the aneurysm, whereby dislodging of the implant out of the aneurysm is inhibited by the distal section.

20. The method of claim 16, wherein, after the expanding, flow into or out of the aneurysm is at least partially diverted.
