1. A system configured to transport a material between the outside and the inside of a patient undergoing laparoscopic surgery and an insufflated abdominal cavity, the system comprising:
- a. a compliant overtube further comprising at least a primary lumen and a proximal end and a distal end;
b. a material capture device comprising a retaining mechanism disposed within the primary lumen; and
c. a helical drive member disposed within the primary lumen and configured to repeatedly shuttle the material capture device between the proximal end and the distal end and into the insufflated abdominal cavity of the patient,wherein the material capture device further comprises a tab that can be disposed between adjoining coils of the helical drive member and further can be disposed into a slot defined in the wall of the primary lumen, wherein the slot constrains the orientation of the material capture device within the primary lumen.

11. A method for transporting a material between the outside and the inside of a natural orifice translumenal endoscopic surgery patient having an insufflated abdomen, comprising:
-
a. inserting through an incision in the natural orifice translumenal endoscopic surgery patient a distal end of a compliant overtube having; i. a primary lumen; ii. a material capture device comprising a retaining mechanism disposed within the primary lumen wherein the retaining mechanism further comprises a passive spring-type grasper and a shape memory alloy; and iii. a drive member configured to repeatedly shuttle the material capture device between the proximal end and the distal end; b. retaining the material in the retaining mechanism of the material capture device; and c. actuating the drive member to advance the material capture device and the retained material from the insufflated abdomen of the patient to the outside of the patient or from the outside of the patient to the insufflated abdomen of the patient. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
