改良型钩腔静脉滤器置换与负荷关系的研究
|
|
Background Vena cava filters are small metal devices that are implanted in the vena cava to protect against pulmonary emboli. Any device intended for use in the human vascular system must demonstrate the ability to withstand repetitive compression. The goal of this test is to compress the stent at 5% and 20% compression to determine a relationship between displacement and the resulting load on the device. By using the Bose® ElectroForce® 3200 Series III test instrument (Fig. 1) and Wintest® software, an accurate plot of displacement against force can be created. |
