摘要：
The present invention relates to a catheter assembly that can deliver a therapeutic composition. The catheter assembly can include an outer balloon with openings for releasing the therapeutic composition. When the catheter assembly is in its contracted state, the openings are closed, and the assembly retains the therapeutic composition. When the catheter assembly is in its dilated state, the openings are open, and the therapeutic composition is released. The present invention also includes methods of making and using such a catheter assembly.
