A guidewire for use in ear, nose and throat procedures may include an elongate core wire having a proximal region and a distal region. The distal region of the core wire may include a flattened portion adapted to provide preferential flexure along at least one axis of the wire. The distal region of the core wire may include a tip portion distal of the flattened portion, where at least one cross-sectional dimension of the tip portion is greater than at least one cross-sectional dimension of the flattened portion. The guidewire may include an outer coil disposed around at least a portion of the elongate core wire. The guidewire may also include an atraumatic tip coupled to the core wire or the outer coil.

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.


Devices and methods wherein an adapter is used to attach an electromagnetic image guidance component to a medical device such that an electromagnetic image guidance system may be used to track the location of the medical device within the body of a human or animal subject.


A set of sinus balloon catheters are provided for treating a patients paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities. These include a balloon catheter with a bend placing a distal segment at 90 to a proximal segment and a balloon catheter which is substantially straight. The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, or sinus to be excised. The catheters have appropriate inflated working diameters and appropriate outer diameters with the balloon deflated that will enable the catheter to be pushed into the respective prepared opening, natural ostium or duct, or sinus cavity to be excised. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, and/or to dilate sinus cavities to remove them.

An apparatus comprises a shaft, an expandable dilator, and at least one ventilation pathway. The shaft defines a longitudinal axis and comprises a distal and proximal ends with at least one shaft lumen. The expandable dilator comprises body with its own proximal and distal ends. The body is configured to transition between a contracted state and an expanded state. The body is configured to dilate a Eustachian tube of a patient in the expanded state. The at least one ventilation pathway is configured to provide ventilation from the distal end of the body to the proximal end of the body when the body is in the expanded state. In some examples, the ventilation pathway comprises a set of transversely oriented vent openings formed through the shaft. In some other examples, the ventilation pathway comprises a space defined between one or more radially outwardly protruding features of the expandable dilator.
