Abstract
A balloon end contact scope device for performing laser-assisted transmyocardial revascularization (TMR) or other surgical and catheter procedures, the device particularly adapted for delivery of laser energy via a laser delivery means and configured to reach inside a body cavity or organ chamber at a point not directly accessible, either visually or otherwise, such as in a lateral or posterior position, the device having a hollow outer lumen, a balloon scope portion with an internal guide tube extending through the balloon portion for directing a laser delivery means or other surgical or catheter device through the visualization balloon toward the area being visualized. The balloon scope portion may have a plurality of guide holes extending therethrough. On the essentially transparent contact viewing surface a friction surface may be applied to facilitate precise positioning and treatment therethrough.
