Abstract:
A drug delivery catheter and method for delivering microcapsules or microspheres containing a drug, pharmacological or other bioactive agent includes a balloon catheter having a coating on the balloon of a soluble biocompatible polymer containing a plurality of microcapsules or microspheres containing a drug or other agent. The balloon is porous to allow it to be inflated with a solvent fluid that passes through the porous wall of the balloon and dissolves the polymer, releasing the microspheres.
