The MRS is a specimen retrieval device that offers surgeons a way to remove malignant specimens during laparoscopic procedures without significantly widening minimally invasive incisions. The proposed device would use expandable braided sleeving to elongate and radially compress large tissue specimens for extraction through the initial incision. Use of this device would allow surgeons to remove large tissue samples through smaller incisions to reduce patient pain, recovery time, postoperative pain and length of hospital stay.
