1. A system for dilating a Eustachian tube (ET) of a patient, the system comprising:
(a) a guide member, wherein the guide member comprises a shaft having a proximal portion and a distal portion, wherein the guide member further comprises a bend at the distal portion, wherein the bend is configured to provide access to an opening in the ET; and (b) a dilation catheter, wherein the dilation catheter is slidable relative to the guide member, the dilation catheter comprising:
(i) a shaft including a proximal portion and a distal portion,(ii) an expandable element disposed at the distal portion of the shaft, and(iii) an actuator disposed at a proximal portion of the shaft, wherein the actuator comprises:
(A) a grasping portion, and(B) an actuating member, wherein the expandable element is configured to transition to an expanded configuration in response to actuation of the actuating member,wherein the grasping portion and actuating member are configured to be grasped in a single hand of an operator to enable the operator to advance the dilation catheter relative to the guide member and to transition the expandable element between expanded and unexpanded configurations with the single hand. |
