Integrated delivery and visualization tool for a neuromodulation system
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.
1. 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 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 visualization system embedded in the elongate shaft, the visualization system comprising an electronic chip positioned within the distal portion and configured to provide video and/or still images to be sent to a viewing system; 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 visualization system comprises a light source.
4. 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 2-15mm.
5. The delivery tool of claim 1 , wherein the visualization system is configured to highlight differences between soft tissue and bone.
6. The delivery tool of claim 1 , further comprising an aperture configured to dispense a fluid to a distal end of the delivery tool.
7. The delivery tool of claim 1 , wherein the contoured distal portion has a thickness of between 2-5mm.
8. A delivery tool configured to deliver a neurostimulator into a patient, comprising:
a handle portion;
an elongate shaft comprising a contoured distal portion having a bifurcated distal dissecting tip, the contoured distal portion 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 visualization system embedded in the elongate shaft, the visualization system including a lens positioned between the bifurcated distal dissecting tip; and
an insertion groove on the elongate shaft configured to deploy the neurostimulator.
9. The delivery tool of claim 8 , wherein the insertion groove is recessed into the elongate shaft.
10. The delivery tool of claim 8 , wherein the lens constructed to allow for a focal length of between 2-15mm.
11. The delivery tool of claim 8 , wherein the visualization system is configured to highlight differences between soft tissue and bone.
12. The delivery tool of claim 8 , wherein the contoured distal portion has a thickness of between 2-5mm.
