Abstract

Various implementations include a tissue extraction system configured for passage through a minimally invasive opening to capture and remove a tissue structure. The system includes an extraction sack and a derrick. The extraction sack is for deposition within a person's body. The derrick includes a frame supporting a pulley system. The pulley system facilitates pulling the extraction sack with the tissue therein through the minimally invasive opening. The tissue extraction system comprises and/or further includes an extraction sack comprising a flexible wall and a toroidal ring. The flexible wall defines an inner chamber and an inflation port. The toroidal ring is disposed within the inner chamber of the flexible wall. The flexible wall of the extraction sack, while in the patient, can be doubled over onto itself and pulled through the toroidal ring to form a double walled sack that can be inflated to eject the tissue structure.
