Abstract: A vascular remodeling device has a plurality of sections, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. Each section has a plurality of interconnected struts that define a waist, a proximal face, and a distal face. Each face comprises (i) a plurality of distal strut portions extending proximally from a distal side of the face, (ii) a plurality of proximal strut portions extending distally from a proximal side of the face, and (iii) a plurality of sub-struts, wherein, from each proximal strut portion, two of the sub-struts each extend to a different one of the distal strut portions.

Abstract: A vascular remodeling device is provided. The device has an anchor portion, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. The device also includes a distal portion sized for deployment in a blood vessel. The distal portion is radially expandable from a collapsed state to an expanded state and has a distal face that is sufficiently occlusive in the distal-to-proximal direction to perform a therapeutic blocking function in an aneurysm neck. The device also has an intermediate portion that interconnects a distal end of the anchor portion and a proximal end of the distal portion. In some embodiments, the anchor portion and/or distal portion has a plurality of interconnected struts.

Abstract: 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.

Abstract: Stents can become twisted during deployment within tortuous vessels such that proper expansion against the vessel wall is inhibited. Stents can be twisted prior to deployment in a direction opposite the direction of twisting during deployment to facilitate full expansion of the stent against the vessel wall along the stent's entire length.

Abstract: A self-expanding stent includes a proximal portion having a first cross-sectional area in an expanded state, a distal portion having a second cross-sectional area in an expanded state, a narrowed portion between the proximal portion and the distal portion, the narrowed portion comprising a cross-sectional area when in an expanded state that is less than the first cross-sectional area and the second cross-sectional area, wherein the narrowed portion is configured to increases flow velocity in the narrowed portion while reducing reduce pressure against a distal wall of the aneurysm by being axially disposed substantially between a proximal edge and a distal edge of an aneurysm neck or ostium, the flow traversing through the lumen of the self-expanding stent. In use, the self-expanding stent is positioned at the site of an aneurysm and expanded via release from a stent delivery device.

Abstract: Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.

Abstract: The medical device can comprise a manipulation member, a mechanical thrombectomy apparatus attached to a distal end of the manipulation member, and flow-restricting apparatus attached to the manipulation member to a location proximal to the mechanical thrombectomy apparatus. A method, for retrieving thrombus from a blood vessel, can comprise advancing a single elongate delivery member carrying a mechanical thrombectomy apparatus and a flow-restricting apparatus through a catheter to the blood vessel, expanding the thrombectomy apparatus and capturing the thrombus with the thrombectomy device, expanding the flow-restricting apparatus to at least partially occlude blood flow toward the thrombus, retracting at least a portion of the thrombectomy apparatus into the flow-restricting apparatus, and retracting the flow-restricting apparatus and the thrombectomy apparatus into the retrieval catheter.
