Abstract: A system for delivering a fluid to a Eustachian tube (ET) of a patient includes a guide member and a tubular member. The guide member includes a shaft having a proximal portion, a distal portion, and a bend at the distal portion. The bend is configured to provide access to an opening in the ET. The system further includes a tubular member comprising a proximal end, a distal end, and a lumen extending therebetween. The tubular member is sized to fit within the ET. One or both of the tubular member and the guide member comprises a first stop member configured to engage the other of the tubular member or the guide member. The first stop member is configured to restrict a distal advancement of the tubular member relative to the guide member.

Abstract: An apparatus includes a proximal coil, a distal coil, a navigation sensor, and a wire. The proximal coil is formed by a wire wrapped in a helical configuration. The distal coil is formed by a wire wrapped in a helical configuration. At least one wrap at a proximal portion of the distal coil is interlocked with at least one wrap at a distal portion of the proximal coil, such that interlocking portions of the proximal and distal coils form a double helix configuration. The navigation sensor is located within the distal coil. The navigation sensor is configured to generate signals in response to movement within an electromagnetic field. The wire extends through the proximal coil. The wire is in electrical communication with the navigation sensor such that the wire is configured to communicate signals from the navigation sensor.

Abstract: A guide catheter system for use in treating the sinus cavity or Eustachian tube is described. The system includes a guide catheter that has a proximal end and a distal end and an elongate shaft between the proximal end and the distal end and a guidewire. The guide catheter includes a deflection feature on a distal tip of the distal end for deflecting the guidewire at a predetermined angle.

Abstract: An apparatus includes a navigational guidewire and a suction device. The navigational guidewire includes a sensing element, an outer member and a conductor. The sensing element is configured to respond to positioning within an electromagnetic field. The conductor extends along the length of the outer member and is in communication with the sensing element. The shaft assembly has an open distal end. The shaft assembly also defines a suction lumen and a guidewire lumen extending through the open distal end. The guidewire lumen is dimensioned to receive the sensing element of the navigational guidewire.
