Abstract

An integrated tool may be used to perform a tracheotomy. The integrated tool may include a trocar and a delivery mechanism, where the delivery mechanism may deploy a stoma stent. The trocar may be actuated impulsively.

Claims (29)

1. A method for performing a tracheotomy on a trachea of a patient, comprising:

providing an integrated tool including a trocar and a delivery mechanism movable within said trocar;

storing energy within said integrated tool;

releasing at least part of said stored energy, wherein said releasing applies an impulsive force in the distal direction to said trocar such that said trocar creates an opening in the trachea; and

deploying a stoma stent in the opening with said delivery mechanism.

2. The method of claim 1 , wherein said delivery mechanism includes a crown configured to hold said stoma stent and an expander movable relative to said crown.

3. The method of claim 1 , wherein said integrated tool includes a control; further comprising actuating said control, wherein said creating and said deploying are both performed in response to said actuating.

4. The method of claim 3 , wherein said actuating is performed with a single input.

5. The method of claim 1 , wherein said creating includes penetrating tissue with the distal end of said trocar and expanding the distal end of said trocar.

6. The method of claim 1 , wherein said creating is performed through the cricoid membrane.

7. The method of claim 1 , further comprising holding the opening open after said creating and during at least part of said deploying.

8. The method of claim 1 , wherein said deploying includes expanding a diameter of at least part of said stoma stent.

9. The method of claim 1 , wherein said stoma stent includes a deployable section and a discard section connected to and proximal to said deployable section; and wherein said deploying includes separating said deployable section from said discard section.

10. A method for performing a tracheotomy on a trachea of a patient, comprising:

providing an integrated tool;

creating an opening in the trachea with said integrated tool;

placing a stoma stent in the opening with said integrated tool, said stoma stent including a plurality of inner flange tines and a plurality of outer flange tines; and

deploying said stoma stent, wherein said deploying includes deploying said inner flange tines to create an inner flange positioned within the trachea and deploying said outer flange tines to create an outer flange positioned outside the trachea wherein said creating and said deploying are performed in response to a single input.

11. The method of claim 10 , wherein said integrated tool includes an expander, at least part of which is within said stoma stent; and wherein said deploying includes translating said expander relative to said stoma stent.

12. The method of claim 10 , further comprising compressing tissue between said inner flange tines and said outer flange tines.

13. The method of claim 10 , wherein said deploying deploys said inner flange tines before said outer flange tines.

14. The method of claim 10 , further comprising inserting a tube through said stoma stent into the trachea.

15. A method for performing a tracheotomy on a trachea of a patient, comprising:

providing a tool including a safety trocar;

applying an impulsive force to said safety trocar to create an opening in the trachea with said safety trocar; and

deploying a stoma stent in the opening with said tool;

wherein said creating and said deploying are performed in response to a single input.

16. The method of claim 15 , wherein said tool includes a cam plate, and wherein said creating and said deploying are controlled by said cam plate.

17. The method of claim 1 , wherein said integrated tool includes a housing in which at least part of said trocar is received, said housing defining an opening through which said trocar extends distally; and wherein said releasing causes said trocar to move distally through said opening relative to said housing.
