Devices, systems and methods for performing image guided interventional and surgical procedures, including various procedures to treat sinusitis and other disorders of the paranasal sinuses, ears, nose or throat.

Apparatus and methods are disclosed for use within an image-guided surgical navigation system for facilitating the combined positioning and orientation of multiple surgical implements. A tool guide having multiple cannulas is tracked by a surgical navigation system in real time. Position data of the tool guide is registered and combined with pre-acquired images by the navigation computer. Concurrent graphical representations of the plurality of cannulas are superimposed over the images and displayed. The display allows the surgeon to place the tool guide into the patient's body and position and orient the plurality of cannulas which are then used to place each of the implements.

A method for treating atrial fibrillation in a heart of a patient includes placing an ultrasonic catheter in a first chamber of the heart; acquiring two-dimensional ultrasonic images of a second chamber of the heart and at least a portion of surrounding structures of the second chamber using the ultrasonic catheter placed in the first chamber; reconstructing a three-dimensional ultrasonic image based on the two-dimensional ultrasonic images; displaying the reconstructed three-dimensional ultrasonic image; identifying at least one key landmark on the reconstructed three-dimensional ultrasonic image; marking the least one key landmark on the reconstructed three-dimensional ultrasonic image; penetrating the septum for accessing the second chamber of the heart while using the marked at least one key landmark for guidance; positioning a sheath through the penetrated septum and within the second chamber of the heart; inserting an ablation catheter through the sheath and into the second chamber of the heart; and ablating a portion of the second chamber of the heart using the ablation catheter while under observation with the ultrasound catheter located in the first chamber of the heart.

A processor embedded in a device includes instructions for procedures to be completed by a user. A display provides the instructions as steps for completion to the user. The processor monitors status of the device to determine completion of the steps before proceeding with the next step. Errors in performing steps are identified by the processor and steps to correct the errors are displayed for execution by the user.

An apparatus for simulating an image-guided procedure. The system comprises an input for receiving a three-dimensional (3D) medical image depicting an organ of a patient, a model generation unit for generating a 3D anatomical model of the organ according to the 3D medical image, and a simulating unit for simulating a planned image-guided procedure on the patient, according to the 3D anatomical model.

The invention provides systems, methods, and instrumentation for aiding the performance of an image guided procedure of the anatomy of a patient such as, for example, the prostate. The invention includes a plurality of lumens therein and a balloon portion or other fixating portion. In some embodiments, the catheter includes a lumen for introducing a contrast agent visible to an imaging modality external to the anatomy of the patient. Image space data of the catheter within the anatomy of the patient may be obtained using the imaging modality. The catheter also includes at least a lumen for inserting a registration device for obtaining patient space data regarding the anatomy of the patient. Other lumens and / or other elements visible to the imaging modality may be used. The image space data may be registered to the patient space data for use during an image guided procedure to the anatomy of the patient.

A method for localizing an internal body structure during an image-guided procedure that includes obtaining a three dimensional image of a body portion containing a targeted structure and selected reference structures; determining a set of landmark point coordinates for defining the location of each of the targeted and reference structures; computing triangulation parameters relating the location of the landmark points for the targeted structure and the reference structures; and, during an image-guided procedure, using the computed triangulation parameters to plot an estimated location of the targeted structure on an intra-operative image in which the reference structures have been identified.
