(54)INTRASACCULAR INVERTING BRAID WITH HIGHLY FLEXIBLE FILL MATERIAL ASSIGNMENT RECORDATION


(57) A tubular braided implant is provided including a braid that can be delivered as a single layer braid, invert into itself during deployment to form at least two nested sacks and include additional braid material that can fill the innermost sack. The additional braid material can loop or coil like a ribbon and/or invert to form smaller and smaller nested sacks. The braid can have a variable braid angle along its length such that when positioned for delivery, the can have a high braid angle near its distal end and a low braid angle near the proximal end. In addition, or as a replacement for the braid material that fills the innermost sack, the implant can include an embolic coil that can loop within the innermost sack.
