  • Publication number: 20100049236
    Abstract: An agent for treating strokes in humans is tested in a non-human subject by selecting an agent for testing and by preparing a selected non-human subject. The preparation includes: inducing a stroke event by advancing a microwire through the arterial system of the subject to a selected intracranial target position, inserting a microcatheter along the microwire and delivering an embolic device to the target position, occluding the artery at the target position by deploying the embolic device, verifying the occlusion and repositioning the embolic device if needed. After a predetermined occlusion interval, reperfusion of the subject is simulated by removing the embolic device and commencing therapy with the selected agent. At appropriate intervals, the effect of the conducted course of therapy is assessed non-invasively until terminal evaluation. In particular aspects, the method involves occluding the middle cerebral artery through an access achieved via the basilar artery.

  • Publication number: 20100035798
    Abstract: The invention provides methods, delivery devices, and compositions for topically oxygenating hypoxic tissue with a hemoglobin-based oxygen earner (HBOC), such as Oxyglobin (Oxyb) in order to promote wound healing and/or reducing hypoxia in post-harvest transplant tissue. The invention can be used, among other things, to stimulate angiogenesis and blood flow at a wound site, reduce wound dilation, and promote wound contraction, thereby increasing the overall rate of wound healing. The invention can also be used, among other things, to reduce oxidative stress in pre-implantation donor organ tissue, as well as stimulate the proliferation of granulation tissue, vessel growth, and promote epithelial healing in transplant tissue once it has been implanted.
