METHODS FOR LOADING A DRUG ELUTING MEDICAL |
摘要 |
<p>Methods and apparatus are disclosed for loading a therapeutic substance or drug within a lumenal space of a hollow wire having a plurality of side openings along a length thereof that forms a hollow drug-eluting stent with a plurality of side drug delivery openings. Loading a drug within the lumenal space of the hollow stent includes a drug filling step, in which the drug is mixed with a solvent or dispersion medium. The lumenal space may be filled with the drug solution or suspension in a reverse fill process and/or a forward fill process. After the drug filling step, a solvent or dispersion medium extracting step is performed to extract the solvent or dispersion medium from within the lumenal space such that only the drug remains within the hollow stent. A stent cleaning step may be performed to an exterior surface of the hollow stent.</p> |
