ABSTRACT:
A surgical access device comprises an introducer with a main endoscopic channel and an auxiliary or secondary instrument channel. The introducer exhibits an extremely narrow cross-sectional profile in order to minimize the size of the portal or other entry point necessary to gain access into the patient's body, thereby minimizing pain and discomfort to the patient and allowing a wide variety of endoscopic procedures to be performed on an out-patient basis. The narrow profile of the introducer is maintained upon introduction by a guide channel which can be stored in a first position so as to closely conform to the profile of the introducer. The guide channel is provided with a set in order to maintain its stored position upon introduction; however, post introductively, the set in the guide channel can be readily released in order to deploy the guide channel and allow insertion of a secondary surgical instrument. The guide channel can be provided with rails or other tracks in order to ensure accurate movement of the instrument to the desired distal location. The guide channel is constructed from a thin but extremely strong and noncompliant membrane material. The present invention also comprises a method of construction and use of the surgical access device.
