Medical devices for the identification and treatment of bodily passages

摘要

Medical devices are described. More particularly, medical devices and methods for the identification and treatment of bodily passages, such as sinus cavities, are described herein. An exemplary medical device comprises an elongate member, a handle, and a wire member. The elongate member is moveable between a first straight, or substantially straight, configuration to a second curved configuration.

1. A medical device comprising:
an elongate member having an elongate member proximal end, an elongate member distal end, and defining a first lumen and a second lumen; a handle disposed on the elongate member and having an actuator moveable between an actuator first position and an actuator second position, the actuator having a first portion and a second portion; a wire member having a wire member first end attached to the first portion of the actuator and a wire member second end disposed within the first lumen and attached to the elongate member; and a cannula having a cannula proximal end attached to the second portion of the actuator and a cannula distal end disposed within the second lumen, the cannula moveable between a cannula first position when the actuator is in the actuator first position and a cannula second position when the actuator is in the actuator second position, in the cannula first position the cannula distal end is disposed at a first location, in the cannula second position the cannula distal end is disposed at a second location that is proximal to the first location; wherein the elongate member is moveable between a substantially straight configuration when the actuator is in the actuator first position and a curved configuration when the actuator is in the actuator second position.
