Abstract

An endoscopy capsule has a capsule housing containing at least one magnetic element that interacts with an extracorporeally applied magnetic field to magnetically navigate the endoscopy capsule within a body lumen of a patient. The capsule housing has a tube connected thereto that is composed of a flexible, non-rigid material, i.e., of insufficient rigidity to feed the capsule housing in the body lumen. The tube is provided with a feed path for providing any of a liquid agent, a gaseous agent, electrical power and data between the capsule housing an extracorporeal source.

Claims

1-15. -15. (canceled)

16. An endoscopy capsule comprising:

a capsule housing configured for in vivo movement through an anatomical lumen of a patient;

at least one magnetic element in said capsule housing that interacts with an externally applied magnetic field to participate in magnetic navigation of the capsule housing through said anatomical lumen;

a tube connected to said capsule housing said tube being comprised of a flexible, non-rigid material;

a component in said capsule housing that participates in an interaction with the patient while the capsule housing is in said anatomical lumen, said component requiring communication with an extracorporeal component in order to participate in said interaction; and

said tube being configured to provide communication to said extracorporeal component and comprising a feed path between said extracorporeal component and said component in said capsule housing selected from the group consisting of a feed path for a fluid agent, a feed path for a gaseous agent, a feed path for electrical supply current, and a feed path for data signals.

17. An endoscopy capsule as claimed in claim 16 wherein said tube is comprised of an inelastic material selected from the group consisting of polypropylene and polytetrafluoroethylene.

18. An endoscopy capsule as claimed in claim 16 wherein said tube has a tube wall with a wall thickness in a range between 0.1 and 0.5 mm.

19. An endoscopy capsule as claimed in claim 18 wherein said tube wall has a thickness of 0.2 mm.

20. An endoscopy capsule as claimed in claim 16 wherein said tube has an external diameter in a range between 2 and 6 mm.

21. An endoscopy capsule as claimed in claim 20 wherein said tube has an external diameter in a range between 3 and 4 mm.

22. An endoscopy capsule as claimed in claim 16 wherein said tube comprises at least two separate channels that are sealed and separated from each other in said tube, respectively forming two different ones of said feed paths in said group.

23. An endoscopy capsule as claimed in claim 16 wherein said tube comprises a tube wall, and wherein said feed path comprises an electrical conductor attached to an interior of, or embedded in, said tube wall.

24. An endoscopy capsule as claimed in claim 16 wherein said feed path is a feed path for said gaseous agent or said liquid agent, and wherein said housing capsule comprises a channel therein terminating in a discharge port at an exterior of said capsule housing, said channel placing said feed tube in communication with said discharge opening to allow said gaseous fluid or said liquid fluid to be discharged through said discharge opening.

25. An endoscopy capsule as claimed in claim 24 comprising a reservoir and a pump connected between said feed tube and said discharge opening, said reservoir allowing accumulation of a quantity of said gaseous agent or liquid agent therein, and said pump operating to pump at least a portion of said quantity from said reservoir to said discharge opening.

26. An endoscopy capsule as claimed in claim 25 wherein said pump is operable in a first direction to pump said quantity from said reservoir to said discharge opening, and is operable in a second, opposite direction to draw said quantity from said feed line into said reservoir.

27. An endoscopy capsule as claimed in claim 25 wherein said pump has an input line communicating said pump with said reservoir and an output line communicating said pump with said discharge opening, and comprising at least one electrically controllable valve selected from the group consisting of a valve located in said input line and a valve located in said output line, said at least one electrically controllable valve being operated to control passage of said quantity from said reservoir to said discharge opening.

28. An endoscopy capsule as claimed in claim 16 wherein said component is a component requiring said liquid agent or said gaseous agent in order to participate in said inner action, and comprising a pump connected between said component and said feed line to pump said fluid agent or said gaseous agent from said feed line to said component.

29. An endoscopy capsule as claimed in claim 28 comprising a reservoir and a pump connected between said feed tube and said discharge opening, said reservoir allowing accumulation of a quantity of said gaseous agent or liquid agent therein, and said pump operating to pump at least a portion of said quantity from said reservoir to said discharge opening.

30. An endoscopy capsule as claimed in claim 16 wherein said feed path comprises an electrical conductor having a current-carrying capacity, and comprising a power source in said capsule housing connected to said electrical conductor, said power source providing an output power that is larger than a power associated with the current-carrying capacity of the electrical conductor, and said power source accumulating said output power from the power associated with the current-carrying capacity of the electrical conductor.

31. An endoscopy capsule as claimed in claim 16 comprising a coupling element that couples said tube to said capsule housing and allows rotation of said capsule housing relative to said tube.

32. An endoscopy capsule as claimed in claim 16 comprising a decoupleable attachment element connecting said tube to said capsule housing and allowing decoupling of said tube from said capsule housing.

33. An endoscopy capsule as claimed in claim 16 wherein said capsule housing comprises a main housing section and a detachable housing section that is detachable from said main housing section, and wherein said component is contained in said detachable housing section.

34. An endoscopy capsule as claimed in claim 16 comprising an insertion element attached to said capsule housing, said insertion element mechanically controlling movement of said capsule housing relative to said anatomical lumen to perform movement functions selected from the group consisting of advancement of said capsule housing into said anatomical lumen, retraction of said capsule housing from said anatomical lumen, and a resting movement of said capsule housing in said anatomical lumen.
