Abstract

Methods and apparatus for delivering a neurostimulator to a target tissue are provided which may include any number of features. One feature is a delivery tool comprising a handle portion, an elongate shaft comprising a contoured distal portion, a visualization system embedded in the elongate shaft, and an insertion groove on the elongate shaft configured to deploy the neurostimulator. The contoured distal portion can be shaped and configured to maintain contact with a posterior maxilla and elevate a periosteum off of the posterior maxilla to avoid soft tissue dissection. In some embodiments, the neurostimulator is implanted in close proximity to or touching the sphenopalatine ganglion.

Claims

1. A delivery tool configured to deliver a neurostimulator into a patient, comprising:

a handle portion;

an elongate shaft comprising a curved distal portion, the curved distal portion being shaped and configured to maintain contact with a posterior maxilla of the patient and elevate a periosteum of the patient off of the posterior maxilla to avoid soft tissue dissection;

a bifurcated distal dissecting tip having a lens positioned between the dissecting tips;

a visualization system embedded in the elongate shaft; and

an insertion groove on the elongate shaft configured to deploy the neurostimulator.

2. The delivery tool of claim 1, wherein the insertion groove is recessed into the elongate shaft.

3. The delivery tool of claim 1 wherein the insertion groove is located on an opposing edge of the delivery tool from the visualization system, allowing for visualization of the deployment of the neurostimulator.

4. The delivery tool of claim 1 wherein the visualization system is a fiberscope.

5. The delivery tool of claim 1 wherein the visualization system comprises a light source.

6. The delivery tool of claim 1 further comprising a lens embedded at the distal portion, the lens constructed to allow for a focal length of between 2-15 mm.

7. The delivery tool of claim 1 wherein the visualization system is configured to highlight differences between soft tissue and bone.

8. The delivery tool of claim 1 wherein the curved distal portion has a thickness of between 2-5 mm.

9. The delivery tool of claim 1 wherein the curved distal portion has an elliptical cross-section.

10. A delivery tool configured to deliver a neurostimulator into a patient, comprising:

a handle portion;

an elongate shaft comprising a contoured distal portion, the contoured distal portion being shaped and configured to maintain contact with a posterior maxilla and elevate a periosteum off of the posterior maxilla to avoid soft tissue dissection;

a bifurcated distal dissecting tip having a lens positioned between the dissecting tips;

a visualization system embedded in the elongate shaft; and

an insertion groove on the elongate shaft configured to deploy the neurostimulator.

11. The delivery tool of claim 10, wherein the insertion groove is recessed into the elongate shaft.

12. The delivery tool of claim 10 wherein the insertion groove is located on an opposing edge of the delivery tool from the visualization system, allowing for visualization of the deployment of the neurostimulator.

13. The delivery tool of claim 10 wherein wherein the visualization system is a fiberscope.

14. The delivery tool of claim 10 wherein the visualization system comprises a light source.

15. The delivery tool of claim 10 further comprising a lens embedded at the distal portion, the lens constructed to allow for a focal length of between 2-15 mm.

16. The delivery tool of claim 10 wherein the visualization system is configured to highlight differences between soft tissue and bone.

17. The delivery tool of claim 10 wherein the distal portion has a thickness of between 2-5 mm.

18. The delivery tool of claim 10 wherein the distal portion has an elliptical cross-section.
