DRUG-ELUTING ANGIOPLASTY BALLOON SYSTEMS

摘要

Systems, devices, and methods are provided for drug-eluting angioplasty balloons. An underlying balloon core member is protected by a core-screen from mechanical and flow shear forces during delivery. Inflation of the balloon opens the screen and pores in the screen permitting drug transfer and absorption. Upon deflation, the screen can be compressed and withdrawn with the balloon.
