Described herein are vascular remodeling devices that 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 anchors 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.

A medical device is provided. The medical device includes a vessel-engaging member attached to a distal end of a delivery wire via a connection mechanism. The vessel-engaging member includes a plurality of rows and a plurality of bridges positioned between each adjacent row, each of the bridges connecting a vertex of a first row with a corresponding vertex of a second row. The vessel-engaging member further includes first and second tapered sections coupled to the connection mechanism, each of the tapered sections projecting from a proximal row and tapering in a direction from the proximal row toward the connection mechanism, each of the tapered sections having a length measured along a longitudinal axis, wherein the length of the first tapered section is less than the length of the second tapered section.

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.

A vascular remodeling device and methods for its use are provided. The device can be positionable at a junction of a bifurcation having an aneurysm and that defines afferent and efferent vessels. Ends of the device can be at least partially inserted into the aneurysm or can anchor the device by being at least partially inserted into efferent vessels. The device can act as a scaffolding to inhibit dislodging of objects out of the aneurysm. The device can permit perfusion to the efferent vessels. Embolic material can be inserted in the aneurysm before, during, and/or after positioning the device.

A vascular remodeling device is provided that can comprise 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 the afferent vessel of a bifurcation. The distal section can comprise at least one embolization coil that can be positioned within an aneurysm to treat the aneurysm and expand from the compressed delivery state to an expanded state upon deployment. The intermediate section can allow perfusion to efferent vessels. Before, during, and/or after the device is positioned, additional embolic material can be used to treat the aneurysm.

An aneurysm therapy system, can include a catheter and an occlusive device. The catheter can have a proximal end, a distal end, and a lumen extending between the proximal and distal ends. The proximal end can include a self-expanding distal section, and the distal section can comprise a coil portion. The occlusive device can be disposed within the lumen and configured to reside in the aneurysm to restrict fluid flow within the aneurysm.

A stent delivery system can include a core member, an introducer sheath, and a microcatheter. The core member can have a distal segment. The stent engagement member can have a generally tubular body positioned about the core member distal segment and can be rotatably coupled to the core member. The engagement member can include an inner layer that has a first durometer and an outer layer that has a second durometer less than the first durometer. The stent can extend along the core member distal segment such that an inner surface of the stent is engaged by the engagement member outer layer for facilitating rotation of the stent relative to the core member.
