Patent ID: 7914573

Claim:
A substantially tubular intraluminal medical device having a longitudinal axis and a radial axis, the device comprising: a plurality of hoops formed from a polymeric material, the plurality of hoops comprising a plurality of radial struts and a plurality of radial arcs, the plurality of radial struts having a first amount of alignment via drawing and annealing of the polymer chains in a direction substantially parallel to the longitudinal axis and the plurality of radial arcs having a second amount of alignment via drawing and annealing of the polymer chains in a direction substantially parallel to the radial axis, the first amount of alignment being greater than the second amount of alignment, and wherein the radial struts are thinner than the radial arcs thereby creating high strain zones in the radial struts relative to the radial arcs; and a plurality of bridges formed from a polymeric material interconnecting the plurality of hoops, wherein the substantially tubular intraluminal medical device has a radial strength in the range from about 13 to 18 psi and an acute recoil at about 13 to 15 percent.
