Abstract

An apparatus for treating a lumen, comprising: at least one mapping tool, wherein the at least one mapping tool is adapted and constructed to provide at least a partial map of an internal surface of the lumen; a display, adapted and constructed to permit the identification of at least one point of interest in the lumen, using the at least partial map; at least one sensor, wherein data retrieved from the at least one sensor is compared to the at least partial map for navigating at least one procedural instrument within the lumen; and, wherein treatment by the at least one procedural instrument occurs when sensed data compared with the at least partial map indicates the that least one procedural instrument is at at least one point of interest. In some exemplary embodiments of the invention, treatment is performed from a remote location in relation to the patient. Optionally, a propulsion apparatus navigates at least one procedural instrument in a lumen in response to commands from a controller.

Claims

1. An apparatus for treating a lumen, comprising:

at least one mapping tool, wherein said at least one mapping tool is adapted and constructed to provide at least a partial map of an internal surface of said lumen;

a display, adapted and constructed to permit the identification of at least one point of interest in said lumen, using said at least partial map;

at least one sensor, wherein sensed data retrieved from said at least one sensor is compared to said at least partial map for navigating at least one procedural instrument within said lumen; and

,

a controller wherein said controller is adapted to automatically generate operational commands to the at least one procedural instrument to commence treatment when said sensed data compared with said at least partial map indicates that said at least one procedural instrument is at at least one point of interest.

2. An apparatus according to claim 1, further comprising feedback sensors adapted and constructed for determining the efficacy of said treatment.

3. An apparatus according to claim 1, further comprising a propulsion apparatus for controllably navigating said at least one procedural instrument in response to operational commands from said controller.

4. An apparatus according to claim 3, wherein said propulsion apparatus comprises a first mechanism for advancing and retracting said at least one procedural instrument.

5. An apparatus according to claim 3, wherein said propulsion apparatus comprises a second mechanism for rotating said at least one procedural instrument.

6. An apparatus according to claim 1, wherein said lumen is a hollow organ.

7. An apparatus according to claim 6, wherein said hollow organ is chosen from a group consisting of a heart, a bladder, a brain, a stomach, an intestine or a gonad.

8. An apparatus according to claim 1, wherein said controller identifies the position of said at least one procedural instrument.

9. An apparatus according to claim 8, further comprising electrophysiology sensors located on said at least one procedural instrument, said sensors in communication with said controller, wherein said sensors assist said controller with said identification of position.

10. An apparatus according to claim 1, wherein controller identifies the position of said at least one procedural instrument by comparing navigating movements to a movement calibration map.

11. An apparatus according to claim 1, wherein said apparatus includes an override allowing for manual intervention.

12. An apparatus according to claim 3, wherein said propulsion apparatus deflects a tip of said procedural instrument in response to said operational commands.

13. An apparatus according to claim 3, wherein said propulsion apparatus advances said procedural instrument into said lumen in response to said operational commands.

14. An apparatus according to claim 3, wherein said propulsion apparatus retracts said procedural instrument from said lumen in response to said operational commands.

21. An apparatus according to claim 1, wherein said apparatus is in communication with a remote location from where said treating is performed.

22. An apparatus according to claim 1, wherein at least one procedural instrument commences treatment automatically when said at least one procedural instrument is at at least one point of interest.

23. An apparatus according to claim 1, wherein at least one procedural instrument commences treatment in response to a manual command when said at least one procedural instrument is at at least one point of interest.

24. A method for treating a lumen, comprising:

mapping at least an internal surface of said lumen, wherein at least a partial map of said lumen internal surface is generated;

identifying at least one point of interest in said lumen using said at least partial map;

navigating at least one procedural instrument through said lumen using sensors to compare sensed data with said at least partial map; and

,
