A THERAPEUTIC BALLOON WITH SYSTEMIC DRUG LOSS PROTECTION AND CONTROLLED PARTICLE SIZE RELEASE

摘要

Systemic drug loss protection devices are disclosed. The drug loss protection device includes a balloon and a drug particulate filter. The drug particulate filter has a plurality of openings and is configured to selectively permit transmission of drug particulates through the filter. Consequently, the size of the openings in the filter regulates transmission of the drug particulates. The drug particulate filter can also be used as an embolic filter.
