Abstract

A medical device can include a capsule for introduction into a body lumen, an umbilicus which is attached to the capsule and which is flexible and of sufficient length to extend outside of the body lumen while the capsule is inside of the body lumen, and means for dispensing a medical agent into the lumen through the capsule. The capsule can include first and second electrodes. A channel can extend through the umbilicus to a plurality of weepholes in the capsule to fluidly connect the medical agent from outside the body lumen to the wall of the body lumen.

Claims

1. A medical device comprising:

a self propelled movable device capable of travel through a patient'"'"'s body lumen;

a source of a medical agent in communication with the movable device for providing the medical agent to the body lumen through the movable device.

2. The medical device of claim 1 comprising a vacuum source operatively associated with the movable device for communicating vacuum to the body lumen.

3. The medical device of claim 1 wherein the source of the medical agent is located outside of the patient'"'"'s body.

4. The medical device of claim 3 comprising a passageway associated with the movable device and providing communication of the medical agent from outside the patients body to the body lumen through the movable device.

5. The medical device of claim 1 comprising at least one electrode for facilitating movement of the movable device through the body lumen.

6. The medical device of claim 1 comprising an umbilicus of sufficient length to extend from the movable device to a point outside the patient'"'"'s body when the movable device is disposed within the body lumen.

7. A medical device comprising:

a self propelled movable device capable of travel through a patient'"'"'s body lumen; and

means for providing a medical agent to the body lumen through the movable device.

8. A medical device comprising:

a capsule for introduction into a patient'"'"'s body lumen;

at least one electrode for electrically stimulating tissue to provide movement of the capsule;

an umbilicus attached to said capsule, said umbilicus of sufficient length to extend outside of said body lumen while said capsule is inside of said body lumen; and

a source of medical agent communicating with openings in the capsule for providing a medical agent from a point outside the body lumen to the wall of the body lumen.

9. The medical device of claim 8 comprising a working channel extending through said capsule and said umbilicus, wherein the working channel is adapted to provide access for a medical device from a point outside the body to the wall of the lumen adjacent the capsule.

10. The medical device of claim 8 comprising a visualization device and a lighting device for visualizing inside of the body lumen.

11. The medical device of claim 8 comprising a vacuum source in operative association with the capsule.

12. The medical device of claim 8 comprising a fluid system for introducing a fluid to the inside of the body lumen.

13. The medical device of claim 9 comprising a fluid seal operatively associated with said working channel.

14. The medical device of claim 8 comprising at least one external electrode for electrical contact with an external surface of the patient.

15. The medical device of claim 8 comprising at least one electrode mounted on said capsule.

16. The medical device of claim 8 comprising a handpiece operably attached to the proximal end of said umbilicus, wherein said working channel extends through at least a portion of the handpiece.

17. The medical device of claim 16 wherein said handpiece includes at least one control selected from the group consisting of vacuum controls, fluid controls, motion controls, electrical stimulation current controls, and electrical stimulation frequency control.

18. A method of applying a medical agent to the inside of a body lumen, the method comprising the steps of:

providing a source of a medical agent; and

dispensing the medical agent to the body lumen through a self propelled movable device adapted for movement within the lumen.

19. The method of claim 18 comprising stimulating tissue to propel the movable device.

20. The method of claim 18 wherein the step of dispensing comprises dispensing a medical agent selected from the group consisting of dyes, stains, lubricants, flourescent materials, gels, radiological materials, muscular contraction agents, antibiotics, analgesics, and oncology pharmaceuticals.
