Visualization system and method for ENT procedures
Summary
The USPTO granted patent US12594125B2 to Acclarent, Inc. covering a visualization system for ENT procedures that integrates image-guided surgery navigation with head-mounted displays. The system uses magnetic position tracking and camera-based image analysis to overlay surgical navigation data onto patient anatomy viewed through a transparent HMD screen. The patent includes 7 inventors and 15 claims.
What changed
USPTO granted patent US12594125B2 to Acclarent, Inc. for a visualization system designed for ENT (ear, nose, throat) surgical procedures. The invention combines image-guided surgery navigation with head-mounted display technology, using magnetic position tracking and optical fiducials integrated with patient tracking assemblies. Surgeons wear an HMD with transparent screens to view patient anatomy overlaid with correlated surgical path data and pre-operative image slices.
Affected parties include medical device manufacturers developing surgical navigation systems, healthcare technology companies, and hospitals performing ENT procedures. Competitors in the surgical visualization and navigation space should review this patent for freedom-to-operate considerations. The patent's 20-year term from the September 2020 filing date means exclusivity extends to September 2040.

Abstract
A visualization system may be implemented with an image guided surgery navigation system for use during ENT procedures. Correlated datasets such as surgical paths and pre-operative image slices may be correlated with the coordinate system of the navigation system for reference during a procedure. A surgeon may wear a head mounted display (“HMD”) having a transparent screen through which the patient anatomy may be viewed. The orientation and distance of the head mounted display relative to the patient anatomy may be determined using magnetic position tracking, image analysis of images captured by a camera of the HMD, or both. Correlated datasets may then be transformed based on the relative distance and orientation and may be displayed via the transparent screen to overlay directly viewed patient anatomy. Some implementations may include optical fiducials integrated with a patient tracking assembly to aid in tracking the patient and determining perspective of the HMD.
