wherein the at least one sensor element is located at the second end of the body member adjacent to the treatment apparatus, wherein the at least one sensor element, disposed inside the second lumen, is configured to obtain position information regarding a position of the at least one sensor element, and wherein the location of the treatment apparatus on the at least one image of the anatomy is able to be determined using the position information of the at least one sensor element.

2. The image-guided medical instrument of claim 1 , wherein the body member comprises a hollow tube.

3. The image-guided medical instrument of claim 1 , wherein the transmission element comprises a torqued cable bundle comprising a hollow wire-rope manufactured as a bundle of twisted filaments, wherein the hollow portion forms the second lumen.

4. The image-guided medical instrument of claim 1 , wherein the body member comprises a hollow helical spring winding.

5. The image-guided medical instrument of claim 1 , wherein the transmission element comprises a wire, and wherein the treatment apparatus is actuated when force is transmitted along the transmission element.

6. The image-guided medical instrument of claim 1 , wherein the transmission element mechanically actuates the treatment apparatus.

7. The image-guided medical instrument of claim 1 , wherein the transmission element includes one or more electrical conductors that serve as signal pathways for the at least one sensor element.

8. The image-guided instrument of claim 1 , wherein the transmission element includes one or more electrical conductors provide electrical energy to the treatment apparatus.

9. The image-guided instrument of claim 1 , wherein the transmission element includes one of a waveguide that transmits microwave energy to the treatment apparatus or an optical fiber that transmits optical energy to the treatment apparatus.

10. The image-guided medical instrument of claim 1 , wherein the position information includes information regarding the orientation of the at least one sensor element.

11. The image-guided medical instrument of claim 1 , wherein the treatment apparatus comprises a biopsy device.

12. The image-guided medical instrument of claim 1 , wherein the treatment apparatus comprises one of a biopsy element, a biopsy notch, endoscopic biopsy forceps, a polypectomy snare, a cytology brush, a biliary guidewire, a sphincterotome, an Endoscopic Retrograde Cholangio-Pancreatography (ERCP) catheter, a stone retrieval balloon, a stent, a lithotripsy basket, a grasper, a basket, rat-tooth forceps, alligator forceps, a sclerotherapy/injection needle, a bipolar coagulation probe, a dilation balloon, a radiofrequency ablation device, a microwave ablation device, embolic delivery device, brachytherapy device, or a cryotherapy probe.

13. The image-guided medical instrument of claim 1 , wherein the tracking device includes an electromagnetic tracking device and the sensor element includes an electromagnetic position sensor.

14. The image-guided medical instrument of claim 1 , wherein sensor element includes one of an inertial sensor, an ultrasonic position sensor, or a fiber optic position sensor.

15. The image-guided medical instrument of claim 1 , wherein the transmission element facilitates receiving electromagnetic energy transmitted from the second end of the body member.

16. A method for facilitating performance of a procedure on a location of interest within a portion of an anatomy of a patient using at least one image of the anatomy of the patient, a tracking device, and an image-guided medical instrument, wherein the image-guided medical instrument includes an operating element, a transmission element comprising a lumen, a treatment apparatus, and at least one sensor element that is trackable by the tracking device, wherein the at least one sensor element is located in the lumen at an end adjacent to the treatment apparatus, the method comprising:

receiving the at least one image of the anatomy of the patient;

receiving position information regarding the position of the at least one sensor, wherein the at least one sensor is disposed inside the lumen of the transmission element;

registering the position information to the at least one image of the anatomy of the patient;

displaying the location of the treatment apparatus on at least one image of the anatomy of the patient, wherein navigation of the treatment apparatus to the location of interest is facilitated using the displayed location of the treatment member; and

actuating, by the transmission element, the treatment apparatus in response to actuation of the operating element, wherein performance of the procedure on the location of interest is based at least in part on the actuation of the treatment apparatus.
