Abstract

In an example, a cryotherapy device includes an elongated shaft, and a cryotherapy delivery member coupled to a distal end of the elongated shaft. The cryotherapy delivery member is configured to apply, from a fixed position in a nasal cavity, thermal energy to at least one of a plurality of nerves in the nasal cavity or a plurality of branches of a nerve in the nasal cavity.

Claims (28)

1. A cryotherapy device, comprising:

an elongated shaft; and

a cryotherapy delivery member coupled to a distal end of the elongated shaft, wherein the cryotherapy delivery member comprises a plurality of plates and a plurality of rods coupling the plurality of plates to the distal end of the elongated shaft,

wherein the cryotherapy delivery member is configured to apply, from a fixed position in a nasal cavity, by one or more of the plurality of plates contacting a nasal wall, cryotherapy to at least one nerve in the nasal cavity or at least one branch of a nerve in the nasal cavity.

2. The cryotherapy device of claim 1 , wherein the cryotherapy delivery member is actuatable between (i) a collapsed state and (ii) an expanded state,

wherein the cryotherapy delivery member has a first size in the collapsed state,

wherein the cryotherapy delivery member has a second size in the expanded state, and

wherein the first size is smaller than the second size.

3. The cryotherapy device of claim 2 , wherein

the plurality of rods couple the plurality of plates to an adjustable pivot point at the distal end of the elongated shaft.

4. The cryotherapy device of claim 3 , wherein the plurality of rods and the adjustable pivot point are configured to adjust at least one of a position, a distance, or an angle of the plurality of plates relative to each other.

5. The cryotherapy device of claim 3 , wherein the plurality of plates are actuatable independently of each other to selectively apply cryotherapy using a subset of the plurality of plates.

6. A cryotherapy device comprising:

an elongated shaft; and

a cryotherapy delivery member coupled to a distal end of the elongated shaft, wherein the cryotherapy delivery member comprises:

a first cryotherapy delivery member configured to apply cryotherapy to a first nerve in a nasal cavity or a first branch of a nerve in the nasal cavity, and

a second cryotherapy delivery member configured to apply cryotherapy to a second nerve in the nasal cavity or a second branch of the nerve in the nasal cavity,

wherein the first cryotherapy delivery member and the second cryotherapy delivery member are configured to be inserted into one nostril of the nasal cavity and are configured to be articulated independently relative to each other.

7. The cryotherapy device of claim 6 , wherein the elongated shaft is bifurcated into a first section and a second section,

wherein the first cryotherapy delivery member is coupled to the first section of the elongated shaft, and

wherein the second cryotherapy delivery member is coupled to the second section of the elongated shaft.

8. The cryotherapy device of claim 7 , wherein the first section of the elongated shaft is configured to position the first cryotherapy delivery member at a posterior region of the nasal cavity, and

wherein the second section of the elongated shaft is configured to position the second cryotherapy delivery member at an antero-superior region of the nasal cavity.

9. The cryotherapy device of claim 6 , wherein the first cryotherapy delivery member and the second cryotherapy delivery member are actuatable independently of each other to selectively apply cryotherapy using only one of the first cryotherapy delivery member and the second cryotherapy delivery member.

10. The cryotherapy device of claim 6 , wherein the first cryotherapy delivery member and the second cryotherapy delivery member are actuatable at the same time to simultaneously apply cryotherapy using both of the first cryotherapy delivery member and the second cryotherapy delivery member.

11. The cryotherapy device of claim 6 , further comprising:

a stabilization feature coupled to the first cryotherapy delivery member to maintain a position of the first cryotherapy delivery member while positioning the second cryotherapy delivery member.

12. The cryotherapy device of claim 11 , wherein the stabilization feature comprises vacuum suction.
