Abstract
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.

Claim 1
Independent Claim
144 words
A contact scope device for performing a transmyocardial revasculariztion (TMR) procedure comprising: a hollow outer lumen having a proximal end and a distal end; a scope portion located at the distal end of the contact scope device, the scope portion including: a contact viewing portion for contact with a wall of the heart, the contact viewing portion defining at least one port adapted for receiving at least one TMR working component for performing TMR on the wall of the heart, the contact viewing portion further including a friction surface area for gripping tissue adjacent the heart wall and providing stability for the contact viewing scope during the TMR procedure; a main body portion disposed between the contact viewing portion and the distal end of the outer lumen; and visualization means for viewing tissue of the wall of the heart through the contact viewing portion.
Claim 2
Dependent Claim
144 words
A contact scope device for performing a transmyocardial revasculariztion (TMR) procedure comprising: a hollow outer lumen having a proximal end and a distal end; a scope portion located at the distal end of the contact scope device, the scope portion including: a contact viewing portion for contact with a wall of the heart, the contact viewing portion defining at least one port adapted for receiving at least one TMR working component for performing TMR on the wall of the heart, the contact viewing portion further including a friction surface area for gripping tissue adjacent the heart wall and providing stability for the contact viewing scope during the TMR procedure; a main body portion disposed between the contact viewing portion and the distal end of the outer lumen; and visualization means for viewing tissue of the wall of the heart through the contact viewing portion.
Claim 3
Dependent Claim
16 words
The device of claim 1 wherein at least a portion of the outer lumen is rigid.
Claim 4
Dependent Claim
16 words
The device of claim 1 wherein at least a portion of the outer lumen is flexible.
Claim 5
Dependent Claim
31 words
The device of claim 1 further comprising at least one guide tube extending at least through the scope portion and providing a pathway for the at least one TMR working component.
Claim 6
Dependent Claim
77 words
The device of claim 4 having a plurality of guide tubes and ports, the guide tubes having proximal ends and distal ends the distal ends of the guide tubes communicating with the ports in the contact viewing portion, the proximal ends of the guide tubes positioned to receive the distal ends of multiple TMR working components, whereby the plurality of guide tubes convey the multiple TMR working components through the scope portion to the tissue being visualized.
