Claims

1. A delivery or removal device for delivering or moving a robotic medical device for laparoscopic surgery, the device comprising:

a. a robotic medical device comprising a first arm and second arm;

b. an overtube comprising;

i. an elongate body having a wall, a first end and a second end;

ii. a device lumen disposed within the body and extending from the first end to the second end; and

iii. a wire lumen disposed within the wall of the elongate body and extending from the first end to the second end, wherein the device lumen is configured to accommodate the passage of the robotic medical device comprising a first arm and a second arm; and

c. a retraction wire configured to be disposed within the wire lumen and device lumen so as to urge the robotic medical device comprising a first arm and a second arm through the device lumen.

2. The device of claim 1, wherein the overtube is sized to be positionable through a laparoscopic port or natural orifice.

3. The device of claim 1, wherein the overtube comprises a protrusion at the second end, wherein the protrusion further defines the wire lumen.

4. The device of claim 3, wherein the protrusion further comprises a robotic medical device receiving component configured to receive the robotic medical device.

5. The device of claim 4, wherein the medical device receiving component comprises at least one magnet configured to magnetically couple to the robotic medical device comprising the first arm and second arm, whereby the robotic medical device comprising a first arm and a second arm releasably couples to the medical device receiving component.

6. The device of claim 5, wherein a portion of the protrusion is defined by a portion of a wall of the device lumen.

7. A delivery or removal device, comprising:

a. a robotic laparoscopic medical device comprising a first arm and second arm;

b. a tubular body having a proximal end and distal end, the tubular body comprising;

i. a device lumen defined by the inner surface wall of the tubular body, the device lumen being sized to receive the robotic laparoscopic medical device, the device lumen comprising a proximal device opening at a proximal end of the tubular body and a distal device opening at a distal end of the tubular body; and

ii. a wire lumen disposed within the wall of the tubular body, wherein the wire lumen is not coaxial with the device lumen, the wire lumen comprising a proximal wire opening at a proximal end of the tubular body wall and a distal wire opening at a distal end of the tubular body wall, wherein the wire lumen has a smaller diameter than the device lumen; and

e. a wire disposed within the wire lumen and device lumen so as to urge the robotic medical device comprising the first arm and second arm through the device lumen.

8. The device of claim 7, wherein the overtube is sized to be positionable through a laparoscopic port or natural orifice.

9. The device of claim 7, wherein the tubular body comprises a protrusion at a distal end of the tubular body, wherein the protrusion further defines the wire lumen.

10. The device of claim 7, wherein the robotic laparoscopic medical device comprising the first arm and second arm further comprises an attachment component disposed on at least one of the first arm or second arm.

11. The device of claim 7, wherein the robotic laparoscopic medical device comprising the first arm and second arm is in vivo device.

12. The device of claim 7, wherein the robotic laparoscopic medical device comprising the first arm and second arm further comprises at least one end effector.

13. The device of claim 12, wherein the at least one end effector is an attachment component.

14. The device of claim 7, wherein the tubular body comprises a protrusion at the distal end, wherein the protrusion further defines the wire lumen.

15. The device of claim 14, wherein the protrusion further comprises a robotic medical device receiving component configured to receive the robotic laparoscopic medical device comprising the first arm and a second arm.

16. The device of claim 15, wherein the medical device receiving component comprises at least one magnet configured to magnetically couple to the robotic medical device comprising the first arm and a second arm, whereby the robotic medical device comprising the first arm and a second arm releasably couples to the medical device receiving component.

17. A delivery or removal device for introducing a robotic laparoscopic medical device comprising a first arm and a second arm into a patient, comprising:

a. a robotic laparoscopic medical device comprising a first arm and a second arm;

b. a tubular body having a proximal end and a distal end and comprising a protrusion at a distal end of the tubular body;

c. a device lumen coextensive with the inner surface of an interior wall of the tubular body, the device lumen being configured to receive the robotic laparoscopic medical device comprising a first arm and a second arm, wherein a portion of the protrusion is defined by a portion of a wall of the device lumen, wherein the device lumen comprises a proximal device opening at a proximal end of the tubular body and a distal device opening at a distal end of the tubular body;

d. a wire lumen disposed within the wall of the tubular body, the wire lumen comprising a proximal wire opening at a proximal end of the tubular body and a distal wire opening at a distal end of the tubular body, wherein the wire lumen has a smaller diameter than the device lumen; and

e. a moveable wire disposed through the device lumen and the wire lumen, the moveable wire comprising an attachment component disposed at or near an end of the moveable wire, wherein the attachment component is configured to be removably attachable to the robotic laparoscopic medical device comprising a first arm and a second arm.
