ABSTRACT:
A tissue collection apparatus is adapted for use in capturing and removing tissue through a hole in a body wall defining a body cavity. The apparatus includes an elongate flexible enclosure sized and configured to extend through the hole with a first end of the enclosure positioned within the body cavity and a second end of the enclosure positioned outside the body cavity. Portions of the distal end define opposing first and second edges which define an opening into the enclosure. A flap extends through the opening and distally of the apparatus to form a lip facilitating placement of tissue through the opening and into the enclosure. The coupling attaches a tension member to the enclosure along at least a point disposed not more distally than the flap. The tension member can be pulled proximally through the hole in the body wall to invert the apparatus without inverting the flap so that the flap covers the second edge of the opening in order to substantially close the opening with the tissue disposed within the enclosure. A method of use includes the steps of pulling the tension member to invert the enclosure and during the pulling step covering the opening with the flap.
