  • Patent number: 11666738
    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.

  • Patent number: 11484714
    Abstract: A navigation system or combination of navigation systems can be used to provide one or more navigation modalities to track a position and navigate a single instrument in a volume. For example, both an Electromagnetic (EM) and Electropotential (EP) navigation system can be used to navigate an instrument within the volume. The two navigation systems may be used separately to selectively individually navigate the single instrument in the volume. Disclosed are also systems and processes to determine a shape of the single instrument either alone or in combination with the position of the instrument. The instrument may be navigated with the addition of tracking devices or with native or inherent portions of the instrument.
