    摘要: The present invention provides a retractor for providing surgical access through a passage in a patient's body, together with a delivery device for positioning the retractor in the patient's body. The retractor comprises an anchoring frame having an upper surface, a lower surface, and an opening therethrough which defines an axial axis. A flexible tensioning member is attached to the frame, and is extendable from the frame out of the body through the passage when the frame is positioned through the passage and into a body cavity. The retractor is held by the delivery device in a collapsed orientation for placement in the patient's body. The delivery device is released from the retractor to allow the retractor to assume an expanded orientation in the patient's body. This tensioning member is selectively tensionable to spread the tissue radially outwardly from the axial axis.

    摘要: 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.
