An Implantable Drug Delivery System Based on Shape-Memory Alloys

摘要: This chapter describes the design of an actively controlled implantable drug delivery device. Its job is to deliver small amounts on a daily basis such that patient no longer needs get or weekly injections. Besides reduction number injections, implanted systems offer many other advantages patient. Implantable devices give more constant level in blood compared By use active device instead passive, could be adapted variations physical activity, changes temperature, etc. In chemotherapy and similar treatments, can at place where needed overall concentration body much lower. The proposed useful for hormonal treatments all drugs are needed. first paragraph, solid will discussed. Main part concentrate liquid system. particular because shape memory actuated microvalve has only silicone parts direct contact with drug. It also very easy produce large volumes incorporate sensing functions.
