Abstract:
1. A sheath for re-engineering blood vessels, the sheath comprising: a first network comprising first fibers, the first fibers having a first biological resorption rate and comprising a straight configuration; a second network comprising second fibers, the second fibers having a second biological resorption rate and at least one waveform, wherein the second biological resorption rate is slower than the first biological resorption rate; and a third network comprising third fibers, the third fibers having a third biological resorption rate and at least one waveform, wherein the third biological resorption rate is slower than the first biological resorption rate and the second biological resorption rate; wherein the first, second, and third networks of fibers are each positioned adjacent to one another; the sheath is configured to be externally wrapped around a vessel within a mammalian body; and wherein when the sheath is externally wrapped around the vessel, the vessel is allowed to expand to the limits allowed by said networks of fibers and re-engineer itself according to a pressure within the vessel.
