Abstract
A catheter system includes a catheter having a first balloon and a second balloon. The first balloon is longitudinally offset from the second balloon along the length of the catheter. The first and second balloons both have expanded and unexpanded states. The second balloon has a drug coating. The catheter system has a first configuration, a second configuration, and a third configuration. In the first configuration, the first balloon is in the unexpanded state and the second balloon is in the unexpanded state. In the second configuration, the first balloon is in the expanded state and the second balloon is in the unexpanded state. In the third configuration, the first balloon is in the expanded state and the second balloon is in the expanded state.

16. A method of deploying a catheter system within a bodily lumen having a lumen wall, the method comprising:
-
providing a catheter having a first balloon and a second balloon, the first balloon longitudinally offset from the second balloon, the second balloon has thereon a drug coating comprising a drug, the first balloon being free of any drug coating; deploying the first balloon within the bodily lumen upstream of the second balloon, wherein deployment of the first balloon stagnates the fluid within the bodily lumen downstream of the first balloon; deploying the second balloon within the bodily lumen in the stagnated fluid; and emitting the drug; transferring the drug to the lumen wall; deflating the first and second balloons; and removing the catheter from the bodily lumen. - View Dependent Claims (17, 18, 19, 20)
