Benefits of technology

The present invention provides methods, systems, and devices for performing image guided procedures for treating diseases or disorders of the ear, nose, throat, and paranasal sinuses. The invention allows for the precise positioning of working devices within the body, without the need for direct line-of-sight endoscopic view. The invention also includes sensor-equipped working devices that can be used to perform image guided FTSI procedures or other ENT procedures. The invention provides a system of working devices specifically useable for image guided FTSI procedures, including a flexible guidewire and a dilation catheter. The invention allows for the advancement of the working device through tortuous regions of the intra nasal anatomy and can be positioned behind obstructive anatomical structures without traumatizing or requiring surgical modification.

Problems solved by technology

In some cases, such dilation of the ostium may fracture, move or remodel bony structures that surround or are adjacent to the ostium.
Electromechanical systems have not been widely used in ENT or sinus surgery.
This is so because a typical endoscopic image is a spatially limited, two dimensional, line-of-sight view.
However, in the new FTSI procedures and other new ENT procedures that use flexible and / or malleable catheters and instruments, it is no longer suitable to mount the sensors on proximal portions of the surgical instruments such that the sensors remain outside of the body.
