ABSTRACT:
Surgical access devices are provided having axially stiff but radially deformable tubular members for insertion into body cavities, organs or blood vessels. The tubular members include inlet sleeves at their proximal ends for facilitating the introduction of surgical throughput devices. The tubular member is axially stiff to permit non-buckling rotation when it is inserted into the patient's body, and is radially deformable, with a substantially constant circumference, so that it conforms to the outer surface configuration of the inserted throughput devices. This minimizes the size of the insertion opening through which the access devices extend and thereby reduces trauma to the patient when the devices are introduced and used.
