Implants described herein can be used as flow diverters and can generally include a plurality of twisting struts extending from a central node. The twisting struts can be twisted along a long axis of each strut. The implant can have a proximal portion affixed to the central node and extending radially from the central node. The twisting struts can have a distal portion. The long axis can be disposed between the proximal portion and the distal portion of the twisting struts. The implant can have a collapsed configuration to be delivered through a catheter into an aneurysm. The implant can have an expanded configuration to anchor within the aneurysm.

Strut flow diverter for cerebral aneurysms and methods for preventing strut entanglement

Implants can be used as flow diverters for treating aneurysms. Implants can include a stabilizing frame for anchoring the implant and an occluding element for diverting blood flow from the aneurysm neck. The stabilizing frame can have two parts, the first part sized to anchor within the sac of the aneurysm and the exterior part sized to anchor against a region of the blood vessel wall adjacent the aneurysm neck. The occluding element can be attached to the interior frame and positioned to occlude the aneurysm neck. The implant can have a central node that can be positioned near the center of the aneurysm neck at which the interior frame is attached to the exterior frame and from which the interior frame and the exterior frame extend.
