Abstract: A laparoscopic access apparatus enabling the removal of tissue or other debris from a surgical site. A catheter having a longitudinal access is provided with a flexible internal sleeve having distal and proximal ends. The sleeve forms an inner channel through which laparoscopic surgical instruments may be passed. The sleeve is mounted with axial tautness along one side of the catheter, it is provided with a loose, baggy portion elsewhere in the catheter defining an inflatable cavity between the catheter and sleeve. A gas port is positioned to enable gas under pressure from a body cavity to enter the inflatable cavity adjacent the distal end thereof to thereby collapse the sleeve and seal the channel.
