  • Apparatuses and media for drug elution and methods for making and using them
    Patent number: 8097224
    Abstract: Embodiments of the invention provide to apparatuses and media used in drug elution studies and methods for making and using them. Such methods and materials can be used for example to assess and control the manufacturing process variability of drug eluting implantable devices such as cardiac leads. One embodiment of the invention is a drug elution method that can be used for in-vitro studies of a matrix impregnated with a compound such as a drug blended polymer matrix. A related embodiment of the invention is an apparatus that is used for example to facilitate the practice of the above-noted methods by inhibiting the evaporation of dissolution media from the vessels in which elution is observed.
