Systems and methods for providing gastrointestinal pain management
First Claim
1. A system for providing gastrointestinal pain management during an endoscopic procedure, comprising:
- an endoscope comprising an operating unit and a flexible shaft that includes at least one lumen; and
an anesthetic collar comprising an annulus, wherein said anesthetic collar is adapted for placement on said flexible shaft so as to permit free transfer of a fluid through said at least one lumen of said flexible shaft to said annulus and wherein said annulus comprises an enclosed chamber having a hollow core and one or more expulsion pore to permit fluid flow into the gastrointestinal tract of a patient.

Abstract
The present invention includes systems and methods for decreasing the pain and discomfort commonly associated with endoscopic procedures, where such procedures may be performed with lower dosage levels of sedative and analgesic drugs. The invention includes use of an anesthetic collar coupled to an endoscope with a flexible shaft. The anesthetic collar allows lubricants, local anesthetics, dyes, and/or other desirable fluids to be passed through the existing lumen of the flexible shaft into an annulus, where the fluid may be distributed through expulsion pores into the gastrointestinal tract. Utilizing the existing lumens found in endoscopes, the present invention allows those fluids that may reduce the pain and discomfort associated with endoscopies such as, for example, local anesthetics and lubricants, to be distributed in an even fashion throughout the gastrointestinal tract or throughout the length and circumference of the endoscope, where such fluids may reduce the drug level requirements for sedative and analgesic agents. Alternatively, the endoscope may be redesigned for streamlined integration with the anesthetic collar or to accomplish the same function of distributing local anesthetics and lubricants, in an even fashion throughout the gastrointestinal tract or throughout the length and circumference of the endoscope, The invention can also be used with endoscopes without existing lumens.

16. An apparatus for providing gastrointestinal pain management during an endoscopic procedure comprising:
-
a lumen extending from a fluid delivery mechanism, wherein said lumen is capable of being inserted through an internal tubular cavity along a flexible shaft of an endoscope and passing beyond the distal end of said shaft; and
a head comprising a plurality of expulsion pores, wherein said head is connected to the distal end of said lumen so as to allow free flow of fluid from said lumen through said expulsion pores so as to facilitate comprehensive dispersion of said fluids into a patient'"'"'s gastrointestinal tract. - View Dependent Claims (17, 18, 19)

20. A flexible shaft for an endoscope for providing fluids during an endoscopic procedure, comprising:
-
an image receiving window;
a light projecting window;
an instrument lumen for passing instruments related to endoscopic procedures into said patient'"'"'s gastrointestinal tract;
a fluid lumen extending along the length of said flexible shaft so as to permit free transfer of a fluid; and
one or more outlet lumens connected to said fluid lumen and arranged such that said fluid passing through said fluid lumen is distributed in an even fashion throughout the path of travel of said flexible shaft. - View Dependent Claims (21)

22. A method for delivering fluids to the gastrointestinal tract of a patient during an endoscopic procedure, comprising:
-
providing an endoscope comprising a flexible shaft;
providing a fluid delivery means, wherein the fluid delivery means may be one of an anesthetic collar, an insertion member, and a fluid lumen and outlet lumens integrated into said flexible shaft;
preparing the endoscope for insertion;
inserting the endoscope into the patient;
ascertaining whether fluid delivery is desired; and
delivering fluids through said fluid delivery means into the gastrointestinal tract of said patient. - View Dependent Claims (23, 24)
