SINUS DILATION SYSTEM AND METHOD
First Claim
1. A surgical system for dilating a region of a patient'"'"'s nasal sinus system, the system comprising:
- a first sinus dilation instrument including;
a handle defining a front end opposite a back end;
a rigid probe extending distally from the front end of the handle, the rigid probe defining;
a proximal end at the front end of the handle,a distal tip opposite the proximal end,a curved segment between the proximal end and the distal tip;
a balloon secured over the rigid probe adjacent the distal tip, wherein a spatial location of the balloon relative to the curved segment is fixed;
an inflation path fluidly connected to an interior of the balloon;
wherein a curvature and a longitudinal location of the curved segment is configured to locate the balloon within one of a frontal sinus, a maxillary sinus, and a sphenoid sinus following insertion of the distal tip through a naris of the patient; and
a connector associated with the handle and configured to be electronically coupled to an image guidance system of the type to allow for a display of a position of the first sinus dilation instrument within the patient relative to a pre-operative image of the patient'"'"'s anatomy.

Abstract
A sinus dilation instrument useful with a navigation system and including a handle, a rigid probe, a balloon, and an identifier device. The probe extends from the handle, forms a curved segment, and carries the balloon. The identifier device is programmed to generate a signal indicative of an instrument identification assigned to the instrument, and is a frontal, maxillary or sphenoid sinus instrument. The signal is formatted to be recognized by an IGS. Once connected, the IGS recognizes the instrument and can retrieve information indicative of a spatial location of the balloon, for example via an instrument tracking device. A surgeon can “plug and play” the sinus dilation instrument with the IGS to perform a procedure.
