Occlusion perfusion catheter
First Claim
1. A method of visualizing a lumen comprising:
- a) inserting a catheter into the lumen, said catheter comprising a longitudinal axis;
b) isolating a treatment region within the lumen;
c) optionally evacuating the isolated treatment region;
d) optionally flushing the isolated treatment region; and
e) introducing a visualization means into the isolated treatment region, via said catheter, wherein said visualization means may turn about the longitudinal axis via torque applied to said visualization means, and wherein said visualization means may activate a photoreactive agentwherein said catheter comprises an agent delivery lumen, and said agent delivery lumen comprising a delivery skive port, and said introducing comprises;
i) selecting a pressure to be detected within the delivery skive port or within the agent delivery lumen; and
ii) detecting said pressure.

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.
