Abstract

Provided herein are expandable devices, rail systems, and motorized devices. In one embodiment, an expandable device comprises an expandable sac having a tool housed therein. The expandable device is optionally configured for operation while inside a body cavity. The expandable device optionally comprises at least one rail in the sac, and at least one railed device coupled to the rail for movement there on. Movement of the railed device on the rail is provided by, for example, a motor such as an electromagnetic motor or an inch-worm type motor. Expandable devices can be used, for example, to perform minimally invasive medical procedures requiring access to a body cavity. Expandable devices can also be used, for example, to provide safe and stable transport of instruments to the body cavity.

Claims

1. A mobile device comprising:

a motor, wherein;

a. the motor comprises a lead car, an intermediate car, and a trail car;

b. each of the lead car, the intermediate car, and the trail car comprises an electromagnet, wherein each of the electromagnets is independently operable;

c. the intermediate car weighs less than the lead car;

d. the intermediate car weighs less than the trail car;

e. the lead car weighs less than a combined weight of the intermediate car and the trail car; and

f. the trail car weighs less than a combined weight of the intermediate car and the lead car.

2. The mobile device of claim 1, wherein the electromagnets are arranged in a substantially collinear configuration such that a pole of each of said electromagnets is oriented for interaction with a pole of another of said electromagnets.

3. The mobile device of claim 2, further comprising a rail, wherein each of the lead car, the intermediate car, and the trail car is arranged on the rail for travel there on.

4. The mobile device of claim 3, further comprising a distance limiter for restraining the cars from moving greater than a maximum distance from each other.

5. The mobile device of claim 2, further comprising a distance limiter for restraining the cars from moving greater than a maximum distance from each other.

6. The mobile device of claim 1, further comprising a distance limiter for restraining the cars from moving greater than a maximum distance from each other.

7. The mobile device of claim 6, wherein the distance limiter comprises a cable or a membrane.

8. An expandable device comprising:

the mobile device claim 1 and a sac, wherein

a. the sac is expandable;

b. the sac comprises a rail; and

c. the mobile device is coupled to the rail for movement there on.
