摘要：本发明涉及一种负泊松比可降解形状记忆聚合物血管支架增材制造方法。首先，以负泊松比结构单元为基础，设计径向及轴向具有负泊松比效应的血管支架初始构型并建立所需血管支架三维结构模型；然后，采用微滴喷射增材制造技术，进行负泊松比可降解形状记忆聚合物血管支架的增材制造；最后，测试血管支架的性能。微滴喷射增材制造复杂几何结构血管支架，有效提高血管支架控形控性能力；利用负泊松比效应，实现血管支架的微创植入，支架膨胀过程中血管壁均匀受力有效避免损伤和没有轴向收缩避免支架迁移；同时满足可降解形状记忆聚合物血管支架在外界激励下形状记忆自主逐渐扩张和生物可降解，有效避免支架内再狭窄和植入后再取出困难等问题。

摘要： A thrombosis filter which can be securely affixed at a selected location in the vascular system of a patient and removed when no longer required. A first embodiment of the thrombosis filter includes a plurality of struts having a first grouping and a second grouping. The first grouping of struts and the second grouping of struts radiate in opposite directions. The free ends of the struts include anchoring elements which anchor into the walls of a blood vessel. At least one grouping of struts is comprised of a shape memory material. When these struts are at body temperature, their free ends engage the wall of the blood vessel. When the temperature of the shape memory alloy struts is selectively varied from body temperature, the struts retract into the body portion of the thrombosis filter.

摘要： A stent for placing in a tubular organ so as to support its diameter to remain above a critical diameter. The stent comprises a spiral coil or cylinder made of a two-way shape memory alloy and has a super-elastic state in which the stent's diameter is at least about the critical diameter or more but within a physiological range tolerated by the organ and having a soft state in which the stent's diameter, after changing to this state from the super-elastic state, which is less than the critical diameter. The shape memory alloy has two transition temperatures being within a range that will not damage biological tissue, of which a first transition temperature is a temperature in which it changes from the soft state to the super-elastic state and of which a second transition temperature is a temperature in which it changes from the super-elastic state to the soft state. The arrangement being such that after changing into one of the two states, the stent remains in that state at body temperature.
