Abstract

An apparatus includes a handle assembly, a guide tube, and a wire. The handle assembly includes a body and an actuator. The guide tube extends distally from the handle assembly and includes a distal end. The wire is slidably disposed in the guide tube. The wire has a distal end including a sensor. The sensor is configured to cooperate with a navigation system to generate a map of anatomical structures within a patient. The wire is coupled with the actuator. The actuator is movable relative to the body to move the wire relative to the guide tube.

Claims

1. An apparatus comprising:

(a) a handle assembly, wherein the handle assembly comprises;

(i) a body, and

(ii) an actuator;

(b) a guide tube extending distally from the handle assembly, wherein the guide tube has a distal end; and

(c) a wire slidably disposed in the guide tube, wherein the wire has a distal end including a sensor, wherein the sensor is configured to cooperate with a navigation system to generate a map of anatomical structures within a patient, wherein the wire is coupled with the actuator, wherein the actuator is movable relative to the body to move the wire relative to the guide tube.

2. The apparatus of claim 1, wherein the handle assembly further comprises a cartridge, wherein the cartridge is configured to removably couple with the body, wherein the actuator is integrated into the cartridge such that the actuator is removable from the body.

3. The apparatus of any of claim 1, wherein the guide tube is rigid.

4. The apparatus of claim 3, wherein the guide tube has a distal region with a preformed bend.

5. The apparatus of claim 1, wherein at least a distal portion of the guide tube is malleable.

6. The apparatus of claim 1, wherein a distal portion of the wire includes a preformed bend.

7. The apparatus of claim 6, wherein the preformed bend defines an angle with a vertex.

8. The apparatus of claim 6, wherein the preformed bend defines a curve.

9. The apparatus of claim 1, wherein the wire has a distal end with a ball tip.

10. The apparatus of claim 9, wherein the sensor is integrated into the ball tip.

11. The apparatus of claim 1, wherein the sensor comprises a coil, wherein the coil is responsive to movement of the distal end of the wire in an electromagnetic field.

12. The apparatus of claim 1, wherein the actuator is configured to drive the wire between a proximal position relative to the guide tube and a distal position relative to the guide tube, wherein the distal end of the wire is flush with the distal end of the guide tube when the wire is in the proximal position, wherein the distal end of the wire is distal to the distal end of the guide tube when the wire is in the distal position.

13. The apparatus of claim 1, wherein the handle assembly provides a plurality of position indicators, wherein the position indicators comprise a first indicator and a second indicator, wherein the first indicator is associated with the proximal position, wherein the second indicator is associated with the distal position.

14. The apparatus of claim 13, wherein the indicators comprise tactile feedback features, wherein the tactile feedback features comprise detent structures.

15. The apparatus of claim 1, wherein the wire forms a service loop within the handle assembly, wherein a proximal portion of the wire is fixedly secured relative to the handle assembly, wherein the service loop is configured to permit a distal portion of the wire to translate relative to the handle assembly while the proximal portion of the wire remains fixedly secured relative to the handle assembly.

16. An apparatus comprising:

(a) a handle assembly, wherein the handle assembly comprises;

(i) a body, and

(ii) an actuator;

(b) a guide tube assembly extending distally from the handle assembly, wherein the guide tube assembly comprises a rigid member and a malleable member; and

(c) a wire slidably disposed in the guide tube assembly, wherein the wire has a distal end including a sensor, wherein the sensor is configured to cooperate with a navigation system to provide image guided navigation of anatomical structures within a patient, wherein the wire is coupled with the actuator, wherein the actuator is movable relative to the body to move the wire relative to the guide tube.

17. The apparatus of claim 16, wherein the malleable member comprises an inner tube, wherein the rigid member comprises an outer sheath.

18. The apparatus of claim 16, wherein the malleable member comprises at least one lumen, wherein the wire is slidably disposed within a first lumen of the at least one lumen of the malleable member.

19. The apparatus of claim 18, wherein a second lumen of the at least one lumens of the malleable member is configured to provide suction to a distal end of the malleable member.

20. A method of using an apparatus, wherein the apparatus comprises:

(a) a handle assembly, wherein the handle assembly comprises;

(i) a body, and

(ii) an actuator;

(b) a guide tube extending distally from the handle assembly, wherein the guide tube has a distal end; and

(c) a wire slidably disposed in the guide tube, wherein the wire has a distal end including a sensor, wherein the sensor is configured to cooperate with a navigation system to generate a map of anatomical structures within a patient, wherein the wire is coupled with the actuator, wherein the actuator is movable relative to the body to move the wire relative to the guide tube;

wherein the method comprises;

(a) inserting a distal end of the guide tube through a nostril of a patient;

(b) actuating the actuator to drive the wire relative to the guide tube such that the distal end of the wire is located distal to the distal end of the guide tube; and

(c) using the distal end of the wire in conjunction with a navigation system to map anatomical structures within the nasal cavity of the patient.
