VASCULAR REMODELING DEVICE

摘要

Described herein are flexible implantable devices or stents that can conform to the shape of vessels of the neurovasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. In some embodiments, a vascular remodeling device includes a first section and a protruding section. During deployment, the device expands from a compressed configuration to an expanded configuration. The first section anchors the device in an afferent vessel and/or in an efferent vessel of a bifurcation and the protruding section is positioned in the junction of the bifurcation having an aneurysm and across the neck of the aneurysm or at least partially within the aneurysm.

主权项

1. A method of treating an aneurysm at a junction of a bifurcation having an afferent vessel and first and second efferent vessels, the method comprising:
anchoring, in the first efferent vessel, a distal section of a stent while in an expanded configuration; anchoring, in the afferent vessel, a proximal section of the stent while in the expanded configuration; and positioning a protruding section of the stent while in the expanded configuration to abut an ostium of the aneurysm on a side of the aneurysm that is adjacent to the second efferent vessel, wherein, while in the expanded configuration, a maximum cross-sectional dimension of the protruding section is greater than a maximum cross-sectional dimension of the proximal section and a maximum cross-sectional dimension of the distal section.
