Patient-derived tissue implant. (a) Lift the #4 mammary gland using blunt-end forceps and insert the fine tip cross action forceps into the gland. (b) Compress the cross action forceps to open a small pocket. (c) Have an assistant use the fine tip forceps to grasp a piece of patient-derived tumor tissue and insert the tissue into the pocket you are holding open with the cross action forceps. Remove the cross action forceps first to collapse the pocket and then help the assistant remove the fine tip forceps from the pocket without removing the tissue by placing the cross action forceps between the fine tip forceps
