ABSTRACT:
Apparatus and method for expanding a perivascular cavity at a surgical site includes an elongated retractor having a tip at the distal end for convenient insertion into a perivascular cavity, and having a slidable coupler near the proximal end for convenient coupling to an elevator element supported in a retractor frame. The elongated retractor supports an endoscope thereon to facilitate visualization of surrounding tissue during insertion into the perivascular cavity. With the retractor inserted in the cavity, the retractor frame is positioned on the skin in alignment with and straddling the cavity, and the elevator element is selectively coupled to the retractor to elevate the retractor relative to the base of the retractor frame, thereby to expand or distend the cavity to provide ample access to tissues and vessels for surgical manipulations within the cavity.
