Claim Text:
1. A vascular sheath for fortifying a section of vasculature, the sheath comprising: a tubular body having a longitudinal axis, a length, and a lumen extending the length of the tubular body, wherein the tubular body includes a wall, and wherein the tubular body includes a stiffness adapted to fortify a section of animal vasculature having pulsatile blood flow, and wherein the stiffness limits expansion of the tubular body from a first configuration to a second configuration when the pulsatile blood flow pressurizes the section of animal vasculature; a longitudinal slot through the wall and extending along the longitudinal axis, the longitudinal slot spacing apart a first lateral edge of the wall from a second lateral edge of the wall by a first width when the tubular body is in the first configuration and a second width greater than the first width when the tubular body is in the second configuration; and a circular portal in the wall, wherein the longitudinal slot intersects the circular portal, wherein the circular portal includes a first circumference when the tubular body is in the first configuration and a second circumference greater than the first circumference when the tubular body is in the second configuration.
