BACKGROUND It is yet to be determined what effects temperature has on the properties of nitinol in order to simplify the process of removing nitinol self-expanding metal stents (SEMS). MATERIALS AND METHODS We describe the procedure for removal of SEMS in a total of 11 cases with 9 patients. A study involving cooling of nitinol stents in situ with ice water just before their removal was attem...
12 patients with malignant inoperable esophageal obstruction (carcinoma of the esophagus n = 7, carcinoma of the esophagogastric junction n = 3, mediastinal lymph node metastasis n = 2) and high-grade dysphagia were treated with self-expanding metal stents (Ultraflex, Microvasive) made of a nickel titanium alloy (Elastalloy). Other forms of palliation had failed in 9/12 patients. The degree of ...
BACKGROUND There have been few randomized control trials comparing the incidence of stent fracture and primary patency among different self-expanding nitinol stents to date. The SMART™ CONTROL stent (Cordis Corp, Miami Lakes, Florida, United States) has a peak-to-valley bridge and inline interconnection, whereas the COMPLETE™-SE stent (Medtronic Vascular, Santa Rosa, California, United States) ...
BACKGROUND The self-expandable COMPLETE™ stent (Medtronic) has greater elasticity, allowing it to regain its shape after the compression force reduces, and has higher trackability, thus is easier to maneuver through tortuous vessels, whereas the balloon-expandable SCUBA™ stent (Medtronic) has higher radial stiffness and can afford more accurate placement without geographic miss, which is import...
