Embodiment 1

[0154] Example 1. A device configured to move within a body lumen, the device comprising: an outer member including a distal end, a proximal end, and a lumen between the distal end and the proximal end; an inner member slidably disposed In the lumen of the outer member, wherein the inner member includes a distal end and a proximal end; a first controllably expandable element disposed on the outer member; a second controllably expandable element, Provided on the outer member or on the inner member; a connector connecting the outer member and the inner member; and an actuation member capable of sliding between the outer member and the inner member move, thereby alternately extending and retracting the distance between the first controllably expandable element and the second controllably expandable element, wherein the first controllably expandable element and the second controllably expandable element can Expands radially outward to engage the wall of the body cavity.

Embodiment 2

[0155] Example 2. A device configured to move within a body lumen, the device comprising: an outer member including a distal end, a proximal end, a lumen between the distal end and the proximal end, and a first controllably expandable element an inner member slidably disposed within the lumen of the outer member, wherein the inner member includes a distal end, a proximal end, and a second controllably expandable element; a connector connecting the outer member and the inner member; and an actuation member capable of sliding movement between the outer member and the inner member to alternately extend and retract the first controllably expandable element and the second controllably expandable element. A distance between expansion elements, wherein the first controllably expandable element and the second controllably expandable element are capable of expanding radially outward to engage a wall of a body lumen.

Embodiment 3

[0156] Example 3. A device configured to move within a body lumen, the device comprising: an outer member including a distal end, a proximal end, a lumen between the distal end and the proximal end, a first controllably expandable element and a second controllably expandable element; an inner member that is slidably disposed in the lumen of the outer member, wherein the inner member includes a distal end and a proximal end; a connector that connects the outer member and the inner member; and an actuation member capable of sliding movement between the outer member and the inner member to alternately extend and retract the first controllably expandable element and the second controllably expandable element. A distance between expansion elements, wherein the first controllably expandable element and the second controllably expandable element are capable of expanding radially outward to engage a wall of a body lumen.
