Abstract

A laparoscopic access apparatus (10) enabling the removal of tissue (T) or other debris from a surgical site. A catheter (12) having a longitudinal access is provided with a flexible internal sleeve (20) having distal (28) and proximal (22) ends. The sleeve (20) forms an inner channel (32) through which laparoscopic surgical instruments (16) may be passed.
The sleeve (20) is mounted with axial tautness along one side (34) of the catheter (12), it is provided with a loose, baggy portion elsewhere in the catheter (12) defining an inflatable cavity (36) between the catheter (12) and sleeve (20). A gas port (38) is positioned to enable gas under pressure from a body cavity to enter the inflatable cavity (36) adjacent the distal end thereof to thereby collapse the sleeve and seal the channel (32).
