Abstract
A balloon catheter comprises a catheter shaft and a plurality of lumens, having a pair of spaced, inflatable balloons carried on the shaft to define an interballoon space between the balloons. Each of the balloons are connected to a separate inflation lumen to permit separate inflation and deflation. A fluid flow lumen extends through the catheter shaft and communicates with the interballoon space. Preferably, a perfusion lumen extends through the catheter shaft and the distal end to permit the shunting of blood past the inflated balloons. The spaced balloons are made of an elastomeric material, and are capable of being inflated to a diameter greater than their length. The catheter may be used by inflating a first catheter balloon to block a blood vessel. One then adds a therapeutic agent to the blood vessel at a position on one side of the first balloon through a flow lumen in the catheter. One then inflates a second catheter balloon to block the blood vessel and isolate the medication between the two balloons, while avoiding undue pressure increase in the interballoon space.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
