Method and device for remodeling the uncinate process
A method of remodeling the uncinate process associated with a paranasal sinus includes positioning at least one shim member in the infundibulum, the shim member deforming the uncinate process and widening at least a portion of the infundibulum. The infundibulum space may be dilated with a dilating member. Dilation may occur prior to delivery of the at least one shim. The dilation member may be delivered into the sinus cavity via an access passageway formed in the canine fossa.
1. A method of remodeling the uncinate process associated with a paranasal sinus comprising:
positioning at least one shim member in the infundibulum, the shim member having one or more sides longer than the remaining sides, wherein positioning comprises inserting the shim with the one or more longer sides generally oriented in the direction of the infundibulum; and
rotating the shim about 60° to about 90° so as to deform the uncinate process and widen at least a portion of the infundibulum.
2. The method of claim 1 , further comprising a step of dilating the infundibulum with a dilation member.
3. The method of claim 2 , wherein the dilation is performed prior to positioning the at least one shim member in the infundibulum.
4. The method of claim 2 , wherein the dilation is performed with a dilation member delivered into the sinus through an access point in the canine fossa.
5. The method of claim 1 , wherein the shim member is degradable.
6. The method of claim 1 , wherein at least two shims are positioned in the infundibulum.
7. The method of claim 1 , wherein the at least one shim member is rectangular in shape.
8. The method of claim 1 , wherein the at least one shim member includes a gripping member on an exterior surface thereof.
9. The method of claim 8 , wherein the gripping member comprises one or more teeth.
10. The method of claim 1 , wherein the at least one shim member is delivered via an elongate delivery tool.
11. The method of claim 10 , wherein the at least one shim is released from the elongate delivery tool by counter-rotation of the delivery tool.
12. The method of claim 10 , wherein the at least one shim is released from the elongate delivery tool by proximal retraction of the delivery tool.
13. The method of claim 1 , wherein the at least one shim member is delivered transnasally.
14. The method of claim 1 , wherein the one or more longer sides has a length in the range of about 1 mm to about 6 mm.
