Definitions

  • flow sleeve 24 is rotated to an area, preferably a vertical area in this specific embodiment that contains no flow channel to seal anchor channel 16 and lumen membrane 36 , e.g., seal area 42 as shown in FIG. 2B .
  • Ingress ports 28 and 32 and egress ports 30 and 34 are sealed by seal area 42 and anchor channel 16 and lumen membrane 36 are filled with cavity fluid 44 .
  • Cavity fluid 44 is at substantially the same pressure as the cavity.
  • One advantage of this embodiment is that in the event that the tissues surrounding the incision site relax during the procedure, additional pressure can be applied to outer anchor member 158 by additionally moving flow piston 154 proximally to further reduce the volume of fluid chamber 160 .
  • activator 218 comprises a sealing member 222 disposed in drainage channel 212 and attached to a piston 224 .
  • Valve 214 and 216 are simple openings that are sealed by sealing member 222 , as shown.
  • piston 224 and sealing member 222 are pulled upward to expose openings 214 and 216 and fluid/liquid within the membranes would drain downward preferably into the body cavity.
  • openings 214 and 216 are located at the same level to drain both membranes at the same time. Alternatively, one opening can be positioned lower to drain the membrane associated with the lower opening.
  • Another substantially similar spring-biased activator 218 within the same drainage channel 212 is provided to open and close one-way valve or opening 217 , which is preferably located at a lower elevation, to drain fluid chamber 190 .
  • Lumen membranes such as membrane 36 , 104 and 187
  • lumen membrane 36 , 104 and 187 are optional and can be omitted.
  • cannula 10 , 100 , 150 , 180 , 230 , 240 , 270 may only have lumen membrane 36 , 104 , 187 and anchor or outer channel/membrane 16 , 106 , 158 , 188 is omitted.
