摘要

The invention discloses a balloon catheter assembly for delivering nano-carriers to bifurcation lesions in one or more of a main branch and a side branch of a blood vessel bifurcation within 30 to 90 seconds. The balloon catheter assembly includes two or more balloons designed for use in the blood vessel bifurcation. A surface of one or more of the two or more balloons is coated with the nano-carriers. The nano-carriers include one or more drugs encapsulated with one or more biological agents.
