Endoscopic tissue stabilization device and related methods of use

Abstract

Embodiments of the invention include a sleeve for use in a body lumen defined by body tissue. The sleeve includes a collapsible wall defining a lumen and including an inflatable member configured to increase a volume of the lumen when the inflatable member is in an inflated state, a conduit configured to inflate the inflatable member, and a port defined by the collapsible wall and in flow communication with the lumen.

         21 . A medical method, comprising:
 introducing a sleeve into a body space; and   inflating portions of the sleeve to at least partially engage a tissue wall, wherein the sleeve includes a wall defining a lumen, a port in flow communication with the lumen, and a plurality of non-inflating portions spaced about a circumference of the wall, each of the plurality of non-inflating portions having a dimension along a longitudinal axis of the sleeve that is greater than a dimension about the circumference of the sleeve.   
     
     
         22 . The method of  claim 21 , further comprising:
 introducing a tool through a channel of an endoscope into the lumen of the sleeve.   
     
     
         23 . The method of  claim 21 , further comprising:
 accessing tissue at the port to perform a procedure.   
     
     
         24 . The method of  claim 21 , wherein the port is defined by a non-inflating portion of the wall. 
     
     
         25 . The method of  claim 21 , wherein the port is defined by a planar portion of the wall. 
     
     
         26 . The method of  claim 21 , wherein at least one cautery wire is coupled to the sleeve. 
     
     
         27 . The method of  claim 21 , wherein the port is defined by a portion of the wall recessed from at least one inflatable portion. 
     
     
         28 . The method of  claim 21 , wherein the sleeve further includes a plurality of inflatable portions configured to expand to the same diameter. 
     
     
         29 . The method of  claim 28 , wherein at least one of the plurality of inflatable portions is at a distal-most end of the sleeve, and at least one of the non-inflating portions contacts the at least one of the plurality of inflatable portions at the distal-most end of the sleeve. 
     
     
         30 . The method of claim.  29 , wherein the sleeve further includes a pouch. 
     
     
         31 . A medical method, comprising:
 introducing a sleeve into a body space; and   expanding the sleeve to at least partially engage a tissue wall, wherein the sleeve includes a wall defining a lumen and a port in flow communication with the lumen, wherein the port is defined by a planar, non-inflating portion of the wall.   
     
     
         32 . The method of  claim 31 , further comprising:
 introducing a tool through a channel of an endoscope into the lumen of the sleeve.   
     
     
         33 . The method of  claim 31 , further comprising:
 accessing tissue at the port to perform a procedure.   
     
     
         34 . The method of  claim 31 , wherein at least an exterior portion of the sleeve is coated with a drug. 
     
     
         35 . The method of  claim 31 , wherein the sleeve further includes a plurality of inflatable portions configured to expand to the same diameter. 
     
     
         36 . The method of  claim 35 , wherein at least one of the plurality of inflating portion is adjacent to the planar, non-inflating portion. 
     
     
         37 . A medical method, comprising:
 introducing a sleeve into a body space;   expanding the sleeve to at least partially engage a tissue wall, wherein the sleeve includes a wall defining a lumen and a port in flow communication with the lumen;   accessing tissue at the port to perform a procedure;   applying suction to the lumen of the sleeve; and   aspirating tissue into the lumen of the sleeve through the port.   
     
     
         38 . The method of  claim 37 , further comprising:
 introducing a tool through a channel of an endoscope into the lumen of the sleeve.   
     
     
         39 . The method of  claim 38 , further comprising:
 accessing the tissue in the lumen of the sleeve with the tool to perform a procedure.   
     
     
         40 . The method of  claim 37 , further including aspirating tissue through of a distal end of the sleeve via a suction device in flow communication with the lumen.
