Abstract

Catheters for occluding, visualizing, irrigating, evacuating, and delivering agents to a treatment area are disclosed. The catheters comprise a catheter body comprising five lumens, first and second occlusion balloons coupled to the catheter body, an optional space-occupying balloon coupled to the catheter body and disposed between the first and second occlusion balloons, and an optional visualization means that enables visualization between the first and second occlusion balloons. Methods for using these catheters are also disclosed. A method comprises inflating the first and second occlusion balloons, inflating the space-occupying balloon, allowing fluid to exit via an evacuation lumen, optionally irrigating or aspirating to facilitate fluid exit via said lumen, and delivering an agent to a treatment area via the agent lumen.
