Abstract

A removal pouch that is utilized for removing body tissue from the interior of the body as part of a minimally invasive surgical procedure. The specimen removal pouch includes an elongated body and a gas vent. The elongated body has an interior portion to collect specimen from a body cavity of a patient. The gas vent is configured to allow passage of gas from the interior portion of the elongated body to an external environment during removal of the pouch from within the body cavity of a patient.

First claim

1 - 12 . (canceled)

13 . A method of removing a specimen from a fluid-filled location within a patient, the method comprising:
inserting a specimen removal pouch at least partially through an incision of a patient to the fluid-filled location; moving a proximal mouth of the specimen removal pouch around the specimen such that the specimen and any fluid within the specimen removal pouch is at least partially positioned within a first portion of the specimen removal pouch; moving the proximal mouth from an open configuration toward a closed configuration to hinder the specimen from moving through the proximal mouth; removing the specimen removal pouch through the incision; and releasing at least some of the fluid through a second portion of the specimen removal pouch, the second portion having a different porosity than the first portion.

14 . The method according to claim 13 , further comprising inserting the specimen removal pouch within a cannula.

15 . The method according to claim 14 , wherein inserting the specimen removal pouch within a cannula is performed prior to inserting the specimen removal pouch at least partially through an incision of a patient to the fluid-filled location.

16 . The method according to claim 13 , further comprising contacting the specimen removal pouch with a grasping instrument after the specimen removal pouch has be inserted at least partially through the incision.

17 . The method according to claim 13 , further comprising using a grasping instrument to position the specimen through the proximal mouth of the specimen removal pouch.

18 . The method according to claim 13 , wherein moving the proximal mouth from an open configuration toward a closed configuration is performed by pulling a drawstring.

19 . The method according to claim 13 , further comprising decreasing a width of the specimen removal pouch as the specimen removal pouch is removed through the incision.

20 . The method according to claim 13 , wherein the second portion of the specimen removal pouch includes a hydrophobic material.

21 . The method according to claim 13 , wherein the second portion of the specimen removal pouch is located at a distal portion of the specimen removal pouch.

22 . The method according to claim 13 , further comprising filtering the fluid through the second portion of the specimen removal pouch.

23 . The method according to claim 13 , wherein the second portion forms a discontinuity in the first portion.

24 . The method according to claim 13 , wherein a distal-most end of the second portion extends farther distally than a distal-most end of the first portion.

25 . The method according to claim 13 , wherein the fluid that is released through the second portion of the specimen removal pouch is a gas.
