<p>Laser cut bioabsorbable intraluminal devices or stents and methods for forming such an intraluminal device or stent. A precursor sheet or tube of bioabsorbable material is laser cut in the presence of an inert gas to form an intraluminal medical device or stent having a desired geometry or pattern. The device or stent may comprise a helical, or other shape, having the laser cut geometry or pattern imparted thereon. The device or stent may further comprise drugs or bio-active agents incorporated into or onto the device or stent in greater percentages than conventional devices or stents. Radiopaque materials may be incorporated into, or coated onto, the intraluminal device or stent. Precise geometries or patterns are simply and readily achievable using the laser cutting methods in the presence of an inert gas while minimizing damage to the precursor materials.</p> |
