Systems and methods for maintaining a clear visual field during endoscopic procedures

A method for maintaining a clear visual field during endoscopic procedures, the method comprising the steps of:

• attaching a resilient tube to a substantially rigid endoscope, the tube having a proximal end and a distal end and the endoscope having a distal viewing window, the tube being attached to the endoscope such that the distal end of the tube is in proximity to the distal viewing window of the endoscope without obstructing said viewing window;
• and
• selectively forcing fluid through the tube and out of the distal end thereof so as to clear the distal viewing window of the endoscope.

A system for maintaining a clear visual field adjacent a distal viewing window of an endoscope, the system comprising:

• a resilient tube having a proximal end and a distal end, the tube being attached to said endoscope such that the distal end of the tube is in proximity to said distal viewing window of ht endoscope, and the tube being attached to the endoscope by means of fasteners which at least partially encircle the endoscope;
• and
• means connected to the proximal end of the resilient tube for selectively forcing fluid through the tube and out of the distal end thereof.

A method for maintaining a clear visual field during endoscopic procedures, the method comprising the steps of:

• attaching a resilient tube to an endoscope, said attaching step comprising placing at least one fastener around both the tube and the endoscope, the tube having a proximal end and a distal end and the endoscope, the tube having a proximal end and a distal end and the endoscope having a distal viewing window, the tube being attached to the endoscope such that the distal end of the tube is in proximity to the distal viewing window of the endoscope without obstructing said viewing window;
• and
• selectively forming fluid through the tube and out of the distal end thereof so as to clear the distal viewing window of the endoscope.

• a resilient tube having a proximal end and a distal end, the tube being attached to said endoscope such that the distal end of the tube is in proximity to said distal viewing window of the endoscope, and the tube being attached to the endoscope by means of elastic bands which encircle both the tube and the endoscope;
