Abstract
A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess or maxillary sinus) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.
Claims20
A balloon dilation device, comprising:
- a handle having a proximal end and a distal end;
- an inner guide member that extends distally from the distal end of the handle, wherein the inner guide member comprises a lumen extending from a proximal end of the inner guide member to a distal end of the inner guide member, wherein the handle comprises a vent port that is in fluid communication with the lumen of the inner guide member;
- a shaft defining a first lumen in which the inner guide member is disposed;
- an inflatable balloon coupled to a distal portion of the shaft;
- and
- an inflation lumen that defines a fluid channel between (i) an inflation port coupled to the handle and (ii) an interior of the inflatable balloon,
- wherein the vent port is located at a position that is distal of the proximal end of the inner guide member.
A method of using a balloon dilation device comprising:
- advancing a distal end of an inner guide member of the balloon dilation device transnasally to a drainage pathway, wherein the balloon dilation device comprises:
- a handle having a proximal end and a distal end;
- an inner guide member that extends distally from the distal end of the handle, wherein the inner guide member comprises a lumen extending from a proximal end of the inner guide member to a distal end of the inner guide member, wherein the handle comprises a vent port that is in fluid communication with the lumen of the inner guide member;
- a shaft defining a first lumen in which the inner guide member is disposed;
- an inflatable balloon coupled to a distal portion of the shaft;
- and
- an inflation lumen that defines a fluid channel between (i) an inflation port coupled to the handle and (ii) an interior of the inflatable balloon,
- wherein the vent port is located at a position that is distal of the proximal end of the inner guide member;
- and
- after advancing the distal end of the inner guide member to the drainage pathway, inflating the inflatable balloon.
