  • Patent number: 5409483
    Abstract: A surgical probe for use in a hollow vessel or other region of the body which comprises a multi-lumen catheter having a transparent, non-compliant balloon coupled to the distal end, such that the balloon has a known shape when inflated. A direct visualization scope is provided in a first lumen of the multi-lumen catheter providing direct visualization into the hollow vessel through the non-compliant balloon. An adapter is coupled to a second lumen of the multi-lumen catheter near the proximal end to supply a transparent fluid through the second lumen to inflate the balloon to the predefined shape. In this aspect, the balloon operates to clear the scope tip by pressing tissue on the walls of the hollow vessel out of the way of the end of the scope. This provides the user of the device a consistent clear view of the tissue at the tip of the scope. A fiber optic is provided in a third lumen of the multi-lumen catheter to deliver light energy to the hollow vessel through the non-compliant balloon.
