Rate limiting barriers for implantable devices and methods for fabrication thereof |
摘要 |
A method of coating an implantable medical device, such as a stent, is disclosed. The method includes applying a formulation on a first polymer layer containing a therapeutic substance to form a second layer. The formulation can contain a highly hydrophobic polymer or a solvent which is a poor solvent for the drug or the polymer of the first layer. The formulation can have a low surface tension value or a high Weber number value.
