ABSTRACT:
Methods and apparatus are provided for treating an injured or severed nerve pathway, wherein one or more microporous tubes are implanted into the nerve pathway to bridge the injured or severed region. A bioactive matrix including stem cells and nutrients is disposed within the microporous tube to facilitate growth of the stem cells and reestablishment of the sensory and motor conductive pathways through the injured or severed region. The microporous tube protects the bioactive matrix during development of the stem cells, and also retains the end regions in proper alignment during the nerve pathway regeneration.
