Abstract
The present invention is directed to a balloon catheter having an irrigation sheath. The balloon catheter has a first expandable membrane forming an occluding balloon. A second membrane forms a sheath about the occluding balloon for providing irrigation to a body lumen. Fluid is provided to the occluding balloon to position the catheter and/or occlude the flow of blood. Fluid is then passed through the sheath to irrigate the target site. In one embodiment of the present invention, the sheath has a plurality of fluid releasing pores.
