Controllable endoscopic sheath apparatus and related method of use
First Claim
1. A sheath apparatus for use with an endoscope, the sheath apparatus comprising:
- a flexible elongated sheath configured to surround an endoscope, the sheath having a flexible lumen extending within the sheath and adapted for positioning adjacent to a surrounded endoscope so as to permit the lumen to move longitudinally in relation to the surrounded endoscope and extend beyond a distal tip of the surrounded endoscope, the lumen having a deflectable distal end and walls defining the contours of the lumen; and
a controller device disposed on the flexible lumen for controlling deflection of the distal end of the lumen, the controller device residing substantially parallel to the walls extending beyond the distal tip of the endoscope when the distal end of the flexible lumen is deflected.

Abstract
A controllable sheath for optimizing the control of surgical instruments at the operation site includes a flexible sheath surrounding an endoscope and including a lumen extending along the walls of the sheath and adjacent to the endoscope. The lumen permits the passage of surgical instruments from the proximal end of the endoscopic device to the operation site. The lumen extends beyond the distal end of the endoscope and deflects at the distal end as desired by the operator'"'"'s manipulation of a controller device. This distal end deflection may occur through various different techniques where the ability to deflect the lumen gives the operator increased control and maneuverability over the surgical implements located in the lumen. Depending upon the particular requirements of the surgical procedure, the controllable sheath may include any number of lumens capable of distal end deflection.

10. An endoscopic device comprising:
-
an endoscope; a flexible elongated sheath for surrounding the endoscope, the sheath having a flexible lumen extending within the sheath and adjacent to the endoscope, the lumen being longitudinally extendable beyond a distal tip of the endoscope and having a deflectable distal end and walls defining the contours of the lumen; and a controller device disposed on the flexible lumen for controlling deflection of the distal end of the lumen, the controller device residing substantially parallel to the walls extending beyond the distal end of the endoscope when the distal end of the flexible lumen is deflected. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for using an endoscopic device in an endoscopic procedure, the endoscopic device including an endoscope, a flexible elongated sheath surrounding the endoscope, and a flexible lumen having walls defining the contours of the lumen, the flexible lumen extending within the sheath and adjacent to the endoscope for containing a surgical tool, the method comprising the steps of:
-
inserting the endoscopic device into a body cavity of a patient; maneuvering the endoscopic device through the body cavity and proximate to an operation site; longitudinally extending a distal end of the lumen beyond a distal tip of the endoscope; and deflecting the extended distal end of the lumen to maneuver the surgical tool by manipulating a controller device disposed on the lumen, whereby the controller device resides substantially parallel to the walls extending beyond the distal tip of the endoscope when the distal end of the flexible lumen is deflected. - View Dependent Claims (20, 21, 22, 23)

24. A sheath apparatus for use with an endoscope comprising:
-
a sheath configured to surround an endoscope, the sheath having a tube extending within it and adapted for positioning adjacent to a surrounded endoscope, the tube having walls defining the contours of the tube and the tube being capable of moving longitudinally in relation to the surrounded endoscope and extending beyond a distal tip of the surrounded endoscope; and a controller disposed on the tube for deflecting the distal end of the tube, the controller residing substantially parallel to the walls of the distal end of the tube extending beyond the distal tip of the surrounded endoscope when the distal end of the flexible lumen is deflected. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)
