Claim Text:
1. A method of performing gastrointestinal lavage comprising the steps of: providing a tube having a proximal end, a distal end, a flexible section intermediate said proximal end and said distal end, a rigid, expanded section at said distal end, and a main central bore configured to loosely receive a endoscope tube, said proximal end being configured to slide into a gastrointestinal tract, said flexible section intermediate said proximal end and said distal end including a surface defining a medial pleat configured to allow said tube to flex backwards up to about 180° without collapsing said main central bore, said rigid, expanded end section including a distal central bore in communication with said main central bore, and said rigid, expanded end section including a plurality of peripheral bores in communication with said distal central bore and configured to connect a lavage tube and a vacuum tube to said distal central bore; attaching a rubber collar around said distal end of said tube forming an air- and water-tight seal with said distal central bore, said rubber collar having a central bore and being configured to form an air- and water-tight seal with at least a portion of the endoscope; capping said rubber collar with a cap to form an air- and water-tight seal at said distal end of said tube over said central bore of said rubber collar to seal said main central bore at said end of said tube to allow gastrointestinal lavage without the endoscope received in said main central bore; connecting the lavage tube to one of said peripheral bores; connecting the vacuum tube to the other of said peripheral bores; inserting said apparatus into a gastrointestinal tract; and manually controlling said apparatus to apply at least one of lavage from said lavage tube and vacuum from said vacuum tube through said proximal end of said tube within said gastrointestinal tract without the endoscope received in said main central bore.
