Pneumoperitoneum device

Abstract

A method for performing a laparoscopic procedure may include inserting a bag through an opening. The method may also include delivering tissue into the bag, sealing the bag, and inflating the bag to create an artificial pneumoperitoneum that extends the abdomen and provides additional working and viewing space. Further, the method may include carrying out a procedure on the tissue located in the inflated bag.

1 - 60 . (canceled) 
     
     
         61 . A bag for insertion into a body cavity to receive tissue for morcellation, the bag comprising:
 a body portion having a width;   a first access channel opening to the body portion, the first access channel having a width; and   a second access channel opening to the body portion, the second access channel having a width,   the width of the body portion being greater than the width of the first access channel and the width of the second access channel.   
     
     
         62 . The bag of  claim 61 , wherein the first access channel includes an opening at a proximal end, and the body portion is wider than the opening. 
     
     
         63 . The bag of  claim 62 , further including a self-expanding collar forming the opening. 
     
     
         64 . The bag of  claim 61 , wherein each of the first access channel and the second access channel includes an opening, and the body portion is wider than the opening of the first access channel and the opening of the second access channel. 
     
     
         65 . The bag of  claim 61 , wherein the body portion is rounded. 
     
     
         66 . The bag of  claim 61 , wherein a length of the first access channel is between 100 and 300 mm. 
     
     
         67 . The bag of  claim 61 , wherein the first access channel and the second access channel are the only access channels opening to the body portion. 
     
     
         68 . The bag of  claim 61 , wherein the body portion and at least one of the first access channel and the second access channel are formed of a continuous sheet of material. 
     
     
         69 . The bag of  claim 61 , wherein a length of the bag is between 300 and 600 mm. 
     
     
         70 . The bag of  claim 61 , wherein a width of the body portion is between 200 and 500 mm. 
     
     
         71 . A bag for insertion into a body cavity to receive tissue for morcellation, the bag comprising:
 a body portion;   a first access channel extending from the body portion, the body portion changing in width adjacent the first access channel; and   a second access channel extending from the body portion, the second access channel changing in width adjacent the body portion.   
     
     
         72 . The bag of  claim 71 , wherein the body portion changes in width by decreasing in width adjacent the first access channel. 
     
     
         73 . The bag of  claim 71 , wherein the second access channel changes in width by increasing in width adjacent the body portion. 
     
     
         74 . The bag of  claim 71 , wherein the first access channel is wider than the second access channel. 
     
     
         75 . The bag of  claim 71 , wherein a length of the bag is between 300 and 600 mm. 
     
     
         76 . The bag of  claim 71 , wherein a width of the body portion is between 200 and 500 mm. 
     
     
         77 . The bag of  claim 71 , wherein a length of the first access channel is between 100 and 300 mm. 
     
     
         78 . A bag for insertion into a body cavity to receive tissue for morcellation, the bag comprising:
 an open end portion having an opening;   a closed end portion opposite the open end portion, the closed end portion being at least as wide as the opening;   a side wall extending between the open end portion and the closed end portion, the side wall and the closed end portion defining a chamber; and   an access channel opening to the chamber, the access channel extending from an intermediate portion of the side wall, the intermediate portion being spaced apart from the open end portion and the closed end portion.   
     
     
         79 . The bag of  claim 78 , wherein the access channel is a first access channel, and the bag further comprises a second access channel opening to the chamber, the second access channel forming the open end portion. 
     
     
         80 . The bag of  claim 79 , wherein the first access channel has a first central axis, the second access channel has a second central axis, and the central axis of the first access channel and the central axis of the second access channel form an acute angle.
