    摘要: A device for treating or preventing a vascular condition at a mammalian vascular site, comprises an implant formed from a compressible, reticulated elastomeric matrix in a shape conducive to delivery through a delivery instrument. One or more implants are delivered in a compressed state to the mammmalian vascular site where each implant recovers substantially to its uncompressed state following deployment from a delivery instrument. In a preferred embodiment the matrix comprises cross-linked polycarbonate polyurethane-urea or cross-linked polycarbonate polyurea-urethane. In another preferred embodiment the matrix comprises a cross-linked polycarbonate polyurethane. In a yet further embodiment, the matrix comprises thermoplastic polycarbonate polyurethane or thermoplastic polycarbonate polyurethane-urea.
