Claim:
1. A method for treating a patient, the method comprising: providing an elongate member comprising a first inflatable balloon on a distal end of the elongate member; advancing the elongate member within a vessel of the patient until the first inflatable balloon is distal of a desired site within the vessel; providing a catheter comprising an elongate, flexible body, an inflation lumen, a valve in fluid communication with the inflation lumen, and a second inflatable balloon proximal of the valve; advancing the catheter over the elongate member within the vessel of the patient until the second inflatable balloon overlaps with the desired site within the vessel; introducing inflation media through the inflation lumen to inflate the second inflatable balloon to dilate the desired site within the vessel; deflating the second inflatable balloon; retracting the catheter over the elongate member within the vessel of the patient until the second inflatable balloon is proximal of the desired site within the vessel; inflating the first inflatable balloon to obstruct distal flow in the vessel; introducing the inflation media through the inflation lumen to re-inflate the second inflatable balloon to obstruct proximal flow in the vessel; opening the valve to infuse fluid into the vessel between the first inflatable balloon and the second inflatable balloon; closing the valve for a predetermined time period while the fluid is within the vessel; and opening the valve following the predetermined time period to aspirate the fluid from within the vessel.
