at least one light generating element mounted on the sheath,
wherein the at least one light generating element is mounted within three centimeters of a distal end of the sheath.
2. A sheath according to claim 1 , wherein the at least one light generating element comprises at least one light emitting diode.
3. A protective sheath adapted to cover an elongate medical probe, comprising:
an elongate sheath adapted to receive an insertion tube of a medical probe; and
at least one light generating element mounted on the sheath,
wherein the at least one light generating element comprises at least one chemiluminescent vial.
4. A protective sheath adapted to cover an elongate medical probe, comprising:
an elongate sheath adapted to receive an insertion tube of a medical probe;
at least one light generating element mounted on the sheath; and
a battery electrically coupled to the light generating element, at least partially embedded within the sheath.
5. A sheath according to claim 1 , wherein the at least one light generating element is mounted on a distal face of the sheath.
6. A sheath according to claim 1 , comprising a battery electrically coupled to the light generating element, at least partially embedded within the sheath.
7. A sheath according to claim 1 , comprising at least one optic element adapted to change a direction of light emitted by one or more of the at least one light generating element.
8. A sheath according to claim 1 , wherein the elongate sheath comprises a protective sheath suitable to isolate the insertion tube from body tissue.
9. A protective sheath according to claim 1 , adapted to, comprising:
at least one imaging device mounted on the sheath,
wherein the elongate sheath is adapted to isolate the insertion tube from body tissue.
10. A sheath according to claim 9 , wherein the at least one imaging device is mounted on a distal face of the sheath.
11. A protective sheath for an endoscope, comprising:
an elongate sheath adapted to receive an insertion tube of an endoscope and isolate the insertion tube from body tissue; and
a power source at least partially embedded within the sheath.
12. A sheath according to claim 11 , wherein the power source comprises a battery.
13. A sheath according to claim 12 , wherein the battery is at least partially embedded within the sheath within five centimeters from a distal end of the sheath.
14. A sheath according to claim 12 , wherein the battery is rechargeable.
15. A sheath according to claim 12 , wherein the battery has a length at least ten times longer than its width.
16. A sheath according to claim 12 , wherein the battery comprises a plurality of links connected through wires.
17. A sheath according to claim 12 , wherein the battery does not substantially affect the flexibility of the sheath.
18. A sheath according to claim 11 , comprising a wireless power reception port, coupled to the sheath, adapted to wirelessly receive power from a power transmitter external to the sheath.
19. A sheath according to claim 11 , wherein the sheath defines a working channel adapted for passage of fluids between tissue distal to a distal end of the sheath and a proximal end of the sheath.
20. An endoscope assembly, comprising:
an endoscope having a power source and a power consuming element, which are not connected within the endoscope; and
a protective sheath covering the endoscope, including a conductive element which closes a circuit connecting the power source and the power consuming element,
wherein the protective sheath connects the power source to the power consuming element regardless of the relative radial orientation of the sheath and the endoscope.
21. An assembly according to claim 20 , wherein the power consuming element comprises an illumination unit.
22. A sheath according to claim 4 , wherein the at least one light generating element is mounted within three centimeters of a distal end of the sheath.
23. A sheath according to claim 4 , comprising at least one optic element adapted to change a direction of light emitted by one or more of the at least one light generating element.
24. A sheath according to claim 4 , wherein the elongate sheath comprises a protective sheath suitable to isolate the insertion tube from body tissue.
