Abstract: A method for the hemostasis of perforating and bleeding vessel related to intracerebral hemorrhage (ICH) includes navigating an occlusion device into a parent artery and then deploying the occlusive device to transiently occlude bleeding vessels to reduce blood flow and local blood pressure until hemostasis is achieved, while maintaining flow within the parent artery. Embodiments of the occlusion device include a catheter, an expandable member sized for insertion into the mid-cerebral artery (MCA) and having a length sufficient to occlude at least one ostia of the lenticulostriate arteries (LSA), with a flow path for blood provided from a proximal side of the expandable member to a distal side of the expandable member, and a semi-permeable contacting member about the expandable member and adapted to be in contact with a wall of the MCA adjacent the ostia, the semi-permeable member permitting a reduce flow of blood through the ostia.
