Abstract: An apparatus includes a proximal portion and a distal portion attached to the proximal portion. The proximal portion includes a proximal surface. The proximal portion defines a first pathway and a second pathway that both extend distally from the proximal surface. The first pathway is dimensioned to receive a shaft while the second pathway is dimensioned to receive a navigation guidewire. The distal portion includes a distal tip terminating into a distal end. The second pathway extends from the proximal portion into the distal tip.

Abstract: An apparatus includes a shaft, an expandable dilation member, and a bulbous tip. The shaft has a first outer cross-sectional dimension. The dilation member is positioned proximal to the distal end of the shaft. The dilation member is operable to transition between a non-expanded configuration and an expanded configuration. The dilation member is sized to pass through a passageway associated with drainage of a paranasal sinus or a Eustachian tube when the dilation member is in the non-expanded configuration. The bulbous tip is positioned at the distal end of the shaft. The bulbous tip is distal to the dilation member. The bulbous tip has a second outer cross-sectional dimension. The second outer cross-sectional dimension is larger than the first outer cross-sectional dimension. The bulbous tip is removably secured to the distal end of the shaft.

Abstract: An apparatus includes an elongate shaft, a dilation balloon, and a fitting member. The elongate shaft includes an inflation lumen, an irrigation lumen, and at least one irrigation opening. The at least one irrigation opening is in fluid communication with the irrigation lumen. The dilation balloon is at the distal portion of the shaft. The dilation balloon is in fluid communication with the inflation lumen. The fitting member is at the proximal end of the shaft. The fitting member includes an inflation fluid port, an irrigation fluid port, and a blocking structure. The inflation fluid port is in fluid communication with the inflation lumen. The irrigation fluid port is in fluid communication with the irrigation lumen. The blocking structure is adjacent to the irrigation fluid port and defines a gap around the irrigation fluid port.

Abstract: A surgical instrument and method of tracking the surgical instrument includes a shaft, a cutting member, and navigation system. The shaft has a shaft lumen, a shaft window, and a shaft edge. The cutting member is disposed within the shaft lumen and is configured to cyclically move from a first position to a second position relative to the shaft. The cutting member includes a cutting window opening, a cutting edge, and a suction lumen to cut the tissue portion with the cutting member in the first position. The navigation system includes a navigation sensor positioned on at least one of the shaft or the cutting member that is configured to be tracked within a patient for identifying a positional movement of the shaft or the cutting member within the patient.

Abstract: An apparatus includes a processing assembly, a plurality of field generators, and a patient tracking assembly. The patient tracking assembly includes a sensor assembly and a communication assembly. The sensor assembly includes a first body, a first sensor, and an electrical conduit. The first body selectively attaches to a patient. The first sensor is mounted to the first body and generates a signal in response to movement within an electromagnetic field. The communication assembly includes a second body and a cable. The second body rotates relative to the first body from a first rotational position to a second rotational position. The cable extends away from the second body. The cable communicates with the processing assembly. The electrical conduit couples the first sensor with the cable while the casing is in the first rotational position and the second rotational position.

Abstract: An apparatus includes a body assembly, a dilation catheter, a first guide catheter, and a guide catheter identification module. The body assembly includes a first electrical interface. The first guide catheter is configured to slidably receive the dilation catheter. The first guide catheter includes a first rigid shaft and a first guide catheter electrical contact. The first rigid shaft has a first rigid bend formed near the first distal end. The first rigid bend defines a first fixed bend angle. The first guide catheter is configured to be removably coupled with the body assembly such that the first guide catheter electrical contact engages the first electrical interface of the body assembly. The guide catheter identification module is operable to identify the first guide catheter based on engagement between the first guide catheter electrical contact and the first electrical interface of the body assembly.
