... to primarily occur in the radial direction we modeled materials with isotropy using the transport properties in the radial direction. Mass transport properties were determined for a hydrophobic drug surrogate with transport properties similar to those on drug-eluting stents (e.g., hydrophilicity, lipophilicity...

...C. Marchand; F. Heim; B. Durand Percutaneous aortic valve implantation has become an alternative technique to surgical valve replacement in patients with high risk for surgery. This technique is at its beginning and stents used for valve prostheses remain standard vascular stents. These stents...

...Nandini Duraiswamy; Richard T. Schoephoerster; James E. Moore, Jr. Four commercially available stent designs (two balloon expandable—Bx Velocity and NIR, and two self-expanding—Wallstent and Aurora) were modeled to compare the near-wall flow characteristics of stented arteries using computational...

... sputter deposition. Both stress-strain curves and differential scanning calorimetry curves were generated for the film used to fabricate stents. The films used for stents had an A f temperature of approximately 36°C allowing for body activated response from a microcatheter. The 10 μ m film was only...

...P. Mortier; M. De Beule; S. G. Carlier; R. Van Impe; B. Verhegghe; P. Verdonck Stents are small tubelike structures, implanted in coronary and peripheral arteries to reopen narrowed vessel sections. This endovascular intervention remains suboptimal, as the success rate is limited by restenosis...

...Niels Grabow; Martin Schlun; Katrin Sternberg; Nico Hakansson; Sven Kramer; Klaus-Peter Schmitz Background: The development of endoluminal stents from polymeric materials requires an understanding of the basic mechanical properties of the polymer and the effects of manufacturing and sterilization...
