Abstract

The invention related to a balloon dilation device having a distal end and a proximal end. The balloon dilation device comprises a handle, a shaft, an inflatable balloon and at least one sensor coil. The handle extends from the proximal end of the balloon dilation device towards the distal end of the balloon dilation device. The shaft extends from the distal end of the balloon dilation device towards the proximal end of the balloon dilation device, said shaft having an inflation lumen. The inflatable balloon is fixedly arranged at the shaft. The balloon is fluidly connected to the inflation lumen such that the balloon can be inflated and deflated by feeding a fluid through the inflation lumen into the balloon. The at least one sensor coil is arranged at the shaft. The at least one sensor coil is configured for capturing an electromagnetic field and for providing a sensor coil signal representing position and orientation of the sensor coil.

Claims (18)

1. A system comprising:

a balloon dilation device, the balloon dilation device comprising a shaft having an inflation lumen and a malleable region, the malleable region comprising a distal end, an inflatable balloon fixedly arranged at the shaft such that the inflatable balloon cannot be shifted along the shaft in a longitudinal direction, at least one sensor coil at the malleable region distal end, and at least a second sensor coil that is arranged at the shaft at a non-zero angle to the at least one sensor coil, wherein when the malleable region is formed to have an angle, the balloon comprises a corresponding bend;

a navigation system comprising a field generator configured to generate an alternating electromagnetic field, the navigation system configured to determine a position and an orientation of the balloon dilation device based on sensor coil signals provided by the at least one sensor coil and the at least second sensor coil of the balloon dilation device when the at least one sensor coil and the at least second sensor coil are exposed to the alternating electromagnetic field, wherein the navigation system is further configured to determine a shape of a portion of the balloon dilation device based on the position and orientation of the at least one sensor coil and the at least second sensor coils, whereby the shape of the portion of the balloon dilation device that lies between the at least one sensor coil and the at least second sensor coils is determined; and

a fluid source attached to the balloon dilation device for feeding a fluid into the balloon.

2. The system of claim 1 , further comprising a monitor configured to visualize at least part of the balloon dilation device.

3. The system of claim 1 , wherein the fluid source comprises at least one fluid sensor for measuring a physical quantity of the fluid provided by the fluid source and for providing fluid sensor signals representing the measured physical quantity.

4. The system of claim 1 , wherein the shaft further comprises a central lumen having a distal end.

5. The system of claim 4 , wherein the central lumen has an opening at the distal end.

6. The system of claim 5 , wherein the central lumen comprises a light fiber therein.

7. The system of claim 4 , wherein the balloon dilation device further comprises a marker carrier that is removably arranged inside and extends along a length of the central lumen, wherein the marker carrier comprises the at least one sensor coil.

8. The system of claim 1 , wherein the balloon dilation device further comprises a handle.

9. The system of claim 1 , wherein the inflatable balloon is attached to the shaft of the balloon dilation device in the malleable region.

10. The system of claim 1 , wherein the at least second sensor coil is displaced at a distance in the longitudinal direction from the at least one sensor coil.

11. The system of claim 1 , wherein the at least second sensor coil is arranged at the shaft adjacent to the malleable region.

12. The system of claim 1 , wherein the malleable region of the shaft has a length between about 10 mm and about 60 mm.

13. The system of claim 12 , wherein the malleable region of the shaft has a length between about 20 mm and about 50 mm.

14. The system of claim 13 , wherein the malleable region of the shaft has a length between about 25 mm and about 35 mm.

15. The system of claim 1 , wherein the malleable region of the shaft is made from a material having an ultimate tensile strength of up to 720 Nmm −2 .
