A biodegradable device capable of producing a high radial force is described. Such a force will be created in devices made of relatively inelastic materials that are to be deployed to the vasculature or a body cavity in a patient. As the halves of the devices move together subject to a longitudinal force, at the point where they are in contact and unable to move closer together in the longitudinal direction, a radial force is created. The devices may have a tension element that assists in bringing the device halves together and which may partially and optionally remain within the body of the device.
本文介绍了一种能够产生较大径向力的可生物降解装置。这种力将在由相对无弹性材料制成的装置中产生,这些装置将被部署到病人的血管或体腔中。当装置的两半部分在纵向力的作用下一起移动时,在两半部分接触且无法在纵向方向上靠近的位置,就会产生一个径向力。这些装置可能有一个张力元件,用于帮助将装置的两半连接在一起,该张力元件可以部分地、也可以选择性地留在装置主体内。
