Abstract: An implant system presented herein includes an engagement wire, a pull wire, and a braided implant having a distal ring thereon. The engagement wire has an elongated member with a radially extending engagement feature at its distal end. The braid can be moved from a delivery shape sized to traverse a catheter to an implanted shape sized to occlude an aneurysm neck. When the braid is in the delivery shape, the pull wire and the elongated member extend through the distal ring and the engagement feature is in a distal direction in relation to the distal ring. Once at least a portion of the braid is positioned in the aneurysm, the pull wire and the elongated member can be moved in a proximal direction to engage the engagement feature to the distal ring and move the distal ring proximally, thereby reshaping the braid within the aneurysm.

Abstract: The invention features methods and devices for controlling bleeding from blood vessels that may be damaged as a result of trauma or impact with an object, such as a bullet or shrapnel. The device may be wearable by a user and include one or more components, such as wound sealant and multiple inflatable balloons/bladders.
