Abstract
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.
