Abstract

Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

Claims

1. An intraluminal device comprising:

a proximal section configured to anchor in an afferent vessel;

an intermediate section comprising a plurality of struts configured to allow perfusion to efferent vessels;

a distal section configured to act as a scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm;

wherein each of the plurality of struts is coupled to the distal section at a coupling at a region between a proximal end of the distal section and a distal end of the distal section;

wherein the distal section is biased to transition from a compressed state to a radially expanded state when released from a catheter, wherein, while transitioning from the compressed state to the radially expanded state, the distal end moves radially outwardly and proximally relative to the proximal section, and the proximal end of the distal section moves radially inwardly and distally relative to the proximal section.

2. The intraluminal device of claim 1, wherein, while in the expanded state, the proximal end and the distal end are substantially axially aligned with the coupling.

3. The intraluminal device of claim 1, wherein, while in the expanded state, the distal end defines an outermost cross-sectional dimension that is greater than an outermost cross-sectional dimension of the proximal section.

4. The intraluminal device of claim 1, wherein, while in the expanded state, the proximal end defines an innermost cross-sectional dimension that is less than an innermost cross-sectional dimension of the proximal section.

5. The intraluminal device of claim 1, wherein, while in the expanded state, the proximal end defines a first lumen sized smaller than a second lumen defined by the proximal section.

6. The intraluminal device of claim 1, wherein the proximal section is detachably coupled to a delivery member.

7. An intraluminal device comprising:

a proximal section configured to anchor in an afferent vessel;

an intermediate section comprising a plurality of struts configured to allow perfusion to efferent vessels;

a distal section configured to act as a scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm;

wherein each of the plurality of struts is coupled to the distal section at a coupling at a region between a proximal end of the distal section and a distal end of the distal section;

wherein each of the proximal end and the distal end is biased to pivot about the coupling, such that the distal section at least partially everts when released from a catheter,

wherein, when released from the catheter, the proximal end and the distal end are configured to become substantially axially aligned with the coupling.

8. The intraluminal device of claim 7, wherein, when released from the catheter, the distal end is configured to define an outermost cross-sectional dimension that is greater than an outermost cross-sectional dimension of the proximal section.

9. The intraluminal device of claim 7, wherein, when released from the catheter, the proximal end is configured to define an innermost cross-sectional dimension that is less than an innermost cross-sectional dimension of the proximal section.

10. The intraluminal device of claim 7, wherein, when released from the catheter, the proximal end is configured to define a first lumen sized smaller than a second lumen defined by the proximal section.

11. The intraluminal device of claim 7, wherein the proximal section is detachably coupled to a delivery member.

12. An intraluminal device comprising:

a proximal section configured to anchor in an afferent vessel;

an intermediate section comprising a plurality of struts configured to allow perfusion to efferent vessels;

a distal section configured to act as a scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm;

wherein each of the plurality of struts is coupled to the distal section at a coupling at a region between a proximal end of the distal section and a distal end of the distal section;

wherein the distal section is biased to transition from a compressed state forming a substantially cylindrical shape to a radially expanded state forming a substantially planar shape when released from a catheter,

wherein, while in the expanded state, the proximal end and the distal end are substantially axially aligned with the coupling.
