Medical devices, systems, and kits for the medialization of a vocal cord
View Patent ↗Medical devices, systems, methods, and kits for the medialization of a vocal cord are described. An embodiment of a medical device comprises a proximal portion, a distal portion, and an elongate body extending from the proximal portion to the distal portion. The elongate body defines a thread extending from the proximal portion and the distal portion.
1. A method of medializing a vocal cord within the larynx of a patient, comprising:
making an incision over the thyroid cartilage of said patient;
dissecting soft tissue underlying the incision to expose the lateral aspect of the thyroid cartilage of said patient;
drilling a hole in the thyroid cartilage of said patient at a point half way between the anterior and posterior aspects of the thyroid cartilage;
placing a light source through the hole;
viewing light emitted from the light source; and
advancing a medical device through the hole to move said vocal cord toward a midline of said larynx to achieve an artificial placement of said vocal cord;
wherein the advancing a medical device through the hole is performed while said patient is phonating.
2. The method of claim 1 , further comprising drilling a second hole in the thyroid cartilage of said patient.
3. The method of claim 1 , wherein the advancing a medical device through the hole is performed until the voice of said patient has a desired timbre.
4. The method of claim 1 , further comprising having the patient speak in a normal voice, shout and sing following the advancing a medical device through the hole.
5. The method of claim 1 , further comprising drilling a second hold in the thyroid cartilage and advancing a second medical device through the second hole to move a vocal cord of said patient toward a midline of said larynx to achieve an artificial placement of the vocal cord.
6. A method of medializing a vocal cord within the larynx of a patient, comprising:
making an incision over the thyroid cartilage of said patient;
dissecting soft tissue underlying the incision to expose the lateral aspect of the thyroid cartilage of said patient;
drilling a passageway in the thyroid cartilage of said patient;
introducing a delivery system into the passageway, the delivery system comprising a light source;
confirming placement of the passageway by visualizing light generated by the light source;
advancing a medical device through the passageway to move said vocal cord toward a midline of said larynx to achieve an artificial placement of said vocal cord; and
further comprising measuring the thyroid cartilage before drilling a passageway to identify a suitable location in the thyroid cartilage for drilling a passageway based on the measuring.
7. The method of claim 6 , wherein the measuring comprises measuring the distance from the notch at the superior aspect of the thyroid cartilage to the inferior margin of the thyroid cartilage.
8. The method of claim 7 , further comprising determining the midpoint of the distance.
9. The method of claim 8 , wherein the drilling a passageway is performed such that the passageway is formed at the midpoint.
10. The method of claim 6 , further comprising removing the delivery system from the passageway and passing the delivery system through a medical device adapted to move said vocal cord toward a midline of said larynx to achieve an artificial placement of said vocal cord before the advancing.
11. The method of claim 6 , further comprising introducing a delivery tool into the medical device and applying torque to the delivery tool to achieve the advancing.
12. The method of claim 6 , wherein the advancing a medical device through the hole is performed while said patient is phonating.
13. A method of medializing a vocal cord within the larynx of a patient, comprising:
making an incision over the thyroid cartilage of said patient;
dissecting soft tissue underlying the incision to expose the lateral aspect of the thyroid cartilage of said patient;
measuring the thyroid cartilage to identify the midpoint of the distance from the notch at the superior aspect of the thyroid cartilage to the inferior margin of the thyroid cartilage;
drilling a passageway in the thyroid cartilage of said patient at the midpoint;
introducing a delivery system into the passageway, the delivery system comprising a light source;
confirming placement of the passageway by visualizing light generated by the light source;
removing the delivery system from the passageway;
passing the delivery system through a medical device adapted to move said vocal cord toward a midline of said larynx to achieve an artificial placement of said vocal cord;
introducing the delivery system and the medical device into the passageway; and
advancing the medical device through the passageway to move said vocal cord toward a midline of said larynx to achieve an artificial placement of said vocal cord.
