Disposable fluidic self-propelling robot for traversing a tubular passage

1. A probe for traversing a tubular passage, the probe comprising:

an introducer to be supported at an entrance to the tubular passage, the entrance disposed at a first end of the tubular passage;

a probe tip to traverse the tubular passage;

a tube comprising an inflatable tube segment storable in the probe tip, the inflatable tube segment to be inflated to push the probe tip away from the introducer toward a second end of the tubular passage opposite the first end; and

a sealing mechanism disposed in the probe tip, the sealing mechanism positioned between the inflatable tube segment of the tube and the introducer to maintain the inflatable tube segment in the probe tip in a deflated configuration until deployment from the probe tip during inflation of the inflatable tube segment,

wherein the probe tip defines an interior cavity for storing the inflatable tube segment in the probe tip,

wherein the sealing mechanism is disposed in the probe tip between the inflatable tube segment of the tube within the probe tip and an inflated segment of the tube extending out of the probe tip, such that, as the probe tip traverses the tubular passage, portions of the inflatable tube segment deploy from the probe tip and are inflated to extend a distance between the probe tip and the introducer at the entrance to the tubular passage;

wherein the sealing mechanism comprises a first surface and a second surface for pressing the tube there between.

2. The probe as recited in claim 1 , wherein the probe tip comprises a concave surface proximate to the tube.

3. The probe as recited in claim 1 , further comprising an implement stored in the probe tip.

4. The probe as recited in claim 3 , further comprising a tether to connect the implement to a device outside of the tubular passage.

5. The probe as recited in claim 1 , further comprising a steering mechanism for steering the probe tip.

6. The probe as recited in claim 1 , wherein the sealing mechanism comprises two parallel shafts disposed in the probe tip.

7. The probe as recited in claim 6 , wherein the sealing mechanism comprises two sets of bearings mounted on the two parallel shafts.

8. The probe as recited in claim 6 , comprising an adjustment mechanism configured for adjusting a distance between the two parallel shafts.

9. The probe as recited in claim 8 , wherein the adjustment mechanism comprises first and second set screws.

10. The probe as recited in claim 9 , wherein one of the two parallel shafts is supported by one or more blocks that are slidably supported by the probe tip and adjustable by the first and second set screws.

11. The probe as recited in claim 1 , wherein the probe tip includes a first half and a second half in a clamshell configuration, and wherein the inflatable tube segment in the probe tip is packed between the first half and the second half.

12. The probe as recited in claim 1 , wherein the probe tip comprises a shaft supported in the probe tip, and wherein the inflatable tube segment in the probe tip is wound around the shaft.

13. The probe as recited in claim 12 , wherein the shaft is supported on two bearings.

14. The probe as recited in claim 12 , wherein the shaft includes a received for accepting a winding instrument for winding the tubing onto the shaft.

15. The probe as recited in claim 12 , wherein the inflatable tube segment in the probe tip is fixedly attached to the shaft.
