ABSTRACT
Stents by design can be differentiated based on their composition material, design, and deployment system. Currently, various endovascular therapies exist for the treatment of peripheral arterial disease, including balloon angioplasty, drug-coated balloon angioplasty, bare metal stents, drug-eluting stents, and atherectomy. Intravascular stents provide an internal scaffolding across a stenotic or occluded blood vessel to maintain patency and re-establish flow. As new advances in stenting technologies are developed and introduced, the areas of treatment with stents will continue to broaden. The main properties in the construction of stents are elastic modulus, yield strength, and tensile strength. In contrast, slotted tube stents are created by using a metallic tube and then laser etching the intended stent design. Slotted tube stents exhibit more radial force but are less flexible and harder to deploy than the coiled tube stents. Modular stents have replaced both tube stents due to their construction design which was aimed to combat the limitations of the prior stents.
